Table of Contents

I have scarcely completed my twenty-fifth year, and am arrived at the most memorable æra of my life. However long, or however happy may be my future career, I doubt whether it will ever be my fate to be employed in so glorious an expedition as that in which two French frigates, the Boussole, and the Astrolabe, are at this moment engaged; the first commanded by count de la Perouse, chief of the expedition, and the second by viscount de Langle[1].

The report of this voyage round the world, created too general and lively an interest, for direct news of these illustrious navigators, reclaimed by their country and by all Europe from the seas they traverse, not to be expected with as much impatience as curiosity.

How flattering is it to my heart, after having obtained from count de la Perouse the advantage of accompanying him for more than two years, to be farther indebted to him for the honour of conveying his dispatches over land into France! The more I reflect upon this additional proof of his confidence, the more I feel what such an embassy requires, and how far I am deficient; and I can only attribute his preference, to the necessity of choosing for this journey, a person who had resided in Russia, and could speak its language.

On the 6 September 1787, the king's frigates entered the port of Avatscha, or Saint Peter and Saint Paul[2], at the southern extremity of the peninsula of Kamtschatka. The 29, I was ordered to quit the Astrolabe; and the same day count de la Perouse gave me his dispatches and instructions. His regard for me would not permit him to confine his cares to the most satisfactory arrangements for the safety and convenience of my journey; he went farther, and gave me the affectionate counsels of a father, which will never be obliterated from my heart. Viscount de Langle had the goodness to join his also, which proved equally beneficial to me.

Let me be permitted in this place to pay my just tribute of gratitude to the faithful companion of the dangers and the glory of count de la Perouse, and his rival in every other court, as well as that of France, for having acted towards me, upon all occasions, as a counsellor, a friend, and a father.

In the evening I was to take my leave of the commander and his worthy colleague. Judge what I suffered, when I conducted them back to the boats that waited for them. I was incapable of speaking, or of quitting them; they embraced me in turns, and my tears too plainly told them the situation of my mind. The officers who were on shore, received also my adieux: they were affected, offered prayers to heaven for my safety, and gave me every consolation and succour that their friendship could dictate. My regret at leaving them cannot be described; I was torn from their arms, and found myself in those of colonel Kasloff-Ougrenin, governor general of Okotsk and Kamtschatka, to whom count de la Perouse had recommended me, more as his son, than an officer charged with his dispatches.

At this moment commenced my obligations to the Russian governor. I knew not then all the sweetness of his character, incessantly disposed to acts of kindness, and which I have since had so many reasons to admire[3]. He treated my feelings with the utmost address. I saw the tear of sympathy in his eye upon the departure of the boats, which we followed as far as our sight would permit; and in conducting me to his house, he spared no pains to divert me from my melancholy reflections. To conceive the frightful void which my mind experienced at this moment, it is necessary to be in my situation, and left alone in these scarcely discovered regions, four thousand leagues from my native land: without calculating this enormous distance, the dreary aspect of the country sufficiently prognosticated what I should have to suffer during my long and perilous route; but the reception which I met with from the inhabitants, and the civilities of M. Kasloff and the other Russian officers, made me by degrees less sensible to the departure of my countrymen.

It took place on the morning of 30 September. They set sail with a wind that carried them out of sight in a few hours, and continued favourable for several days. It will readily be believed, that I did not see them depart without offering the most sincere wishes for all my friends on board; the last sad homage of my gratitude and attachment.

Count de la Perouse had recommended diligence to me, but enjoined me, at the same time, upon no pretext to quit M. Kasloff; an injunction that was perfectly agreeable to my inclinations. The governor had promised to conduct me as far as Okotsk, which was the place of his residence, and to which it was necessary that he should repair immediately. I had already felt the happiness of being placed in such good hands, and I made no scruple of surrendering myself implicitly to his direction.

His intention was to go as far as Bolcheretsk, and there wait till we could avail ourselves of sledges, which would greatly facilitate our journey to Okotsk. The season was too far advanced for us to risk an attempt by land, and the passage by sea was not less dangerous; besides there was no vessel either in the port of Saint Peter and Saint Paul, or of Bolcheretsk[4].

M. Kasloff had his affairs to settle, which, with the preparations for our departure, detained us six days longer, and afforded me time to satisfy myself that the frigates were not likely to return. I embraced this opportunity of commencing my observations, and making minutes of every thing about me. I attended particularly to the bay of Avatcha, and the port of Saint Peter and Saint Paul, in order to give a just idea of them.

This bay has been minutely described by captain Cook, and we found his account to be accurate. It has since undergone some alterations; which, it is said, are to be followed by many others; particularly as to the port of Saint Peter and Saint Paul. It is possible indeed, that the very next ship which shall arrive, expecting to find only five or six houses, may be surprised with the sight of an entire town, built of wood, but tolerably fortified.

Such at least is the projected plan, which, as I learned indirectly, is to be ascribed to M. Kasloff, whose views are equally great, and conducive to the service of his mistress. The execution of this plan will contribute not a little to increase the celebrity of the port, already made famous by the foreign vessels which have touched there, as well as by its favourable situation for commerce[5].

To understand the nature, and estimate the utility of this project, nothing more is necessary than to have an idea of the extent and form of the bay of Avatscha, and the port in question. We have already many accurate descriptions, which are in the hands of every one. I shall therefore confine myself to what may tend to illustrate the views of M. Kasloff.

The port of St. Peter and St. Paul, is known to be situated at the north of the entrance of the bay, and closed in at the south by a very narrow neck of land, upon which the ostrog[6], or village of Kamtschatka is built. Upon an eminence to the east, at the most interior point of the bay, is the house of the governor[7], with whom M. Kasloff resided during his stay. Near this house, almost in the same line, is that of a corporal of the garrison, and a little higher inclining to the north, that of the serjeant, who, next to the governor, are the only persons at all distinguished in this settlement, if indeed it deserves the name of settlement. Opposite to the entrance of the port, on the declivity of the eminence, from which a lake of considerable extent is seen, are the ruins of the hospital mentioned in captain Cooke's voyage[8]. Below these, and nearer the shore, is a building which serves as a magazine to the garrison, and which is constantly guarded by a centinel. Such was the state in which we found the port of St. Peter and St. Paul.

By the proposed augmentation, it will evidently become an interesting place. The entrance was to be closed, or at least flanked by fortifications, which were to serve at the same time as a defence, on this side, to the projected town, which was chiefly to be built upon the site of the old hospital; that is, between the port and the lake. A battery also was to be erected upon the neck of land which separates the bay from the lake, in order to protect the other part of the town. In short, by this plan, the entrance of the bay would be defended by a sufficiently strong battery upon the least elevated point of the left coast; and vessels entering the bay could not escape the cannon, because of the breakers on the right. There is at present upon the point of a rock, a battery of six or eight cannon, lately erected to salute our frigates.

I need not add, that the augmentation of the garrison forms a part of the plan, which consists only at present of forty soldiers, or Cossacs. Their mode of living and their dress are similar to the Kamtschadales, except that in time of service they have a sabre, firelock, and cartouch box; in other respects they are not distinguishable from the indigenes, but by their features and idiom.

With respect to the Kamtschadale village, which forms a considerable part of the place, and is situated, as I have already said, upon the narrow projection of land which closes in the entrance of the port, it is at present composed of from thirty to forty habitations, including winter and summer ones, called isbas and balagans; and the number of inhabitants, taking in the garrison, does not exceed a hundred, men, women and children. The intention is to increase them to upwards of four hundred.

To these details respecting the port of St. Peter and St. Paul, and its destined improvements, I shall add a few remarks upon the nature of the soil, the climate, and the rivers. The banks of the bay of Avatscha are rendered difficult of access by high mountains, of which some are covered with wood, and others have volcanos[9]. The valleys present a vegetation that astonished me. The grass was nearly of the height of a man; and the rural flowers, such as the wild roses and others that are interspersed with them, diffuse far and wide a most grateful smell.

The rains are in general heavy during spring and autumn, and blasts of wind are frequent in autumn and winter. The latter is sometimes rainy; but notwithstanding its length, they assured me that its severity is not very extreme, at least in this southern part of Kamtschatka[10]. The snow begins to appear on the ground in October, and the thaw does not take place till April or May; but even in July it is seen to fall upon the summit of high mountains, and particularly volcanos. The summer is tolerably fine; the strongest heats scarcely last beyond the solstice. Thunder is seldom heard, and is never productive of injury. Such is the temperature of almost all this part of the peninsula.

Two rivers pour their waters into the bay of Avatscha; that from which the bay is named, and the Paratounka. They both abound with fish, and every species of water fowl, but these are so wild, that it is not possible to approach within fifty yards of them. The navigation of these rivers is impracticable after the 26 November, because they are always frozen at this time; and in the depth of winter the bay itself is covered with sheets of ice, which are kept there by the wind blowing from the sea; but they are completely dispelled as soon as it blows from the land. The port of St. Peter and St. Paul is commonly shut up by the ice in the month of January.

I should doubtless say something in this place of the manners and customs of the Kamtschadales, of their houses, or rather huts, which they call isbas or balagans; but I must defer this till my arrival at Bolcheretsk, where I expect to have more leisure, and a better opportunity of describing them minutely.

We departed from the port of Saint Peter and Saint Paul the 7 October. Our company consisted of Messrs. Kasloff, Schmaleff[11], Vorokhoff[12], Ivaschkin[13], myself, and the suite of the governor, amounting to four serjeants, and an equal number of soldiers. The commanding officer of the port, probably out of respect to M. Kasloff, his superior, joined our little troop, and we embarked upon baidars[14] in order to cross the bay and reach Paratounka, where we were to be supplied with horses to proceed on our route.

In five or six hours we arrived at this ostrog, where the priest[15], or rector of the district resides, and whose church also is in this place[16]. His house served us for a lodging, and we were treated with the utmost hospitality; but we had scarcely entered when the rain fell in such abundance, that we were obliged to stay longer than we wished.

I eagerly embraced this short interval to describe some of the objects which I had deferred till my arrival at Bolcheretsk, where, perhaps, I may find others that will not be less interesting.

The ostrog of Paratounka is situated by the side of a river of that name, about two leagues from its mouth[17]. This village is scarcely more populous than that of St. Peter and St. Paul. The small pox has, in this place particularly, made dreadful ravages. The number of balagans and isbas seemed to be very nearly the same as at Petropavlofska[18].

The Kamtschadales lodge in the first during summer, and retreat to the last in winter. As it is thought desirable that they should be brought gradually to resemble the Russian peasants, they are prohibited, in this southern part of Kamtschatka, from constructing any more yourts, or subterraneous habitations; these are all destroyed at present[19], a few vestiges only remain of them, filled up within, and appearing externally like the roofs of our ice-houses.

The balagans are elevated above the ground upon a number of posts, placed at equal distances, and about twelve or thirteen feet high. This rough sort of colonnade supports in the air a platform made of rafters, joined to one another, and overspread with clay: this platform serves as a floor to the whole building, which consists of a roof in the shape of a cone, covered with a kind of thatch, or dried grass, placed upon long poles fastened together at the top, and bearing upon the rafters. This is at once the first and last story; it forms the whole apartment, or rather chamber: an opening in the roof serves instead of a chimney to let out the smoke, when a fire is lighted to dress their victuals; this cookery is performed in the middle of the room, where they eat and sleep pell-mell together without the least disgust or scruple. In these apartments, windows are out of the question; there is merely a door, so low and narrow, that it will scarcely suffice to admit the light. The staircase is worthy of the rest of the building; it consists of a beam, or rather a tree jagged in a slovenly manner, one end of which rests on the ground, and the other is raised to the height of the floor. It is placed at the angle of the door, upon a level, with a kind of open gallery that is erected before it. This tree retains its roundness, and presents on one side something like steps, but they are so incommodious that I was more than once in danger of breaking my neck. In reality, whenever this vile ladder turns under the feet of those who are not accustomed to it, it is impossible to preserve an equilibrium; a fall must be the consequence, more or less dangerous, in proportion to the height. When they wish persons to be informed that there is nobody at home, they merely turn the staircase, with the steps inward.

Motives of convenience may have suggested to these people the idea of building such strange dwellings, which their mode of living renders necessary and commodious. Their principal food being dried fish, which is also the nourishment of their dogs, it is necessary, in order to dry their fish, and other provisions, that they should have a place sheltered from the heat of the sun, and at the same time perfectly exposed to the air. Under the collonnades or rustic porticos, which form the lower part of their balagans, they find this convenience; and there they hang their fish, either to the ceiling or to the sides, that it may be out of the reach of the voraciousness of their dogs. The Kamtschadales make use of dogs[20] to draw their sledges; the best, that is the most vicious, have no other kennel than what the portico of the balagans affords them, to the posts of which they are tied. Such are the advantages resulting from the singular mode of constructing the balagans, or summer habitations of the Kamtschadales.

Those of winter are less singular; and if equally large, would exactly resemble the habitations of the Russian peasants. These have been so often described, that it is universally known how they are constructed and arranged. The isbas are built of wood; that is to say, the walls are formed by placing long trees horizontally upon one another, and filling up the interstices with clay. The roof slants like our thatched houses, and is covered with coarse grass, or rushes, and frequently with planks. The interior part is divided into two rooms, with a stove placed so as to warm them both, and which serves at the same time as a fire-place for their cookery. On two sides of the largest room, wide benches are fixed, and sometimes a sorry couch made of planks, and covered with bears skin. This is the bed of the chief of the family: and the women, who in this country are the slaves of their husbands, and perform all the most laborious offices, think themselves happy to be allowed to sleep in it.

Besides these benches and the bed, there is also a table, and a great number of images of different saints, with which the Kamtschadales are as emulous of furnishing their chambers, as the majority of our celebrated connoisseurs are of displaying their magnificent paintings.

The windows, as may be supposed, are neither large or high. The panes are made of the skins of salmon, or the bladders of various animals, or the gullets of sea wolves prepared, and sometimes of leaves of talc; but this is rare, and implies a sort of opulence. The fish skins are so scraped and dressed that they become transparent, and admit a feeble light to the room[21]; but objects cannot be seen through them. The leaves of talc are more clear, and approach nearer to glass; in the mean time they are not sufficiently transparent for persons without to see what is going on within: this is manifestly no inconvenience to such low houses.

Every ostrog is presided by a chief, called toyon. This kind of magistrate is chosen from among the natives of the country, by a plurality of voices. The Russians have preserved to them this privilege, but the election must be approved by the jurisdiction of the province. This toyon is merely a peasant, like those whom he judges and governs; he has no mark of distinction, and performs the same labours as his subordinates. His office is chiefly to watch over the police, and inspect the execution of the orders of government. Under him is another Kamtschadale, chosen by the toyon himself, to assist him in the exercise of his functions, or supply his place. This vice-toyon is called yesaoul, a Cossac title adopted by the Kamtschadales since the arrival of the Cossacs in their peninsula, and which signifies second chief of their band or clan. It is necessary to add, that when the conduct of these chiefs is considered as corrupt, or excites the complaints of their inferiors, the Russian officers presiding over them, or the other tribunals established by government, dismiss them immediately from their functions, and nominate others more agreeable to the Kamtschadales, with whom the right of election still remains.

The rain continuing, we were unable to proceed on our journey; but my curiosity led me to embrace a short interval that offered in the course of the day, to walk out into the ostrog, and visit its environs.

I went first to the church, which I found to be built of wood, and ornamented in the taste of those of the Russian villages. I observed the arms of captain Clerke, painted by Mr. Webber, and the English inscription upon the death of this worthy successor of captain Cook; it pointed out the place of his burial at Saint Peter and Saint Paul's.

During the stay of the French frigates in this port, I had been at Paratounka, in a hunting excursion, with viscount de Langle. As we returned, he spoke of many interesting objects he had observed in the church, and which had entirely escaped my attention. They were, as far as I can remember, various offerings deposited there, he said, by some ancient navigators, who had been shipwrecked. It was my full intention to examine them upon my second visit to this ostrog; but whether it escaped my recollection, or that my research was too precipitate, from the short time that I had to make it, certain it is that I did not discover them.

The village is surrounded with a wood; I traversed it by proceeding along the river, and perceived at length a vast plain which extends to the north and the east as far as the mountains of Petropavlofska. This chain is terminated at the south and west by another, of which the mountain of Paratounka forms a part, and which is about five or six wersts[22] from the ostrog of that name. Upon the banks of the rivers that wind in this plain, there are frequent traces of bears, who are attracted by the fish with which these rivers abound. The inhabitants assured me, that fifteen or eighteen were frequently seen together upon these banks, and that whenever they hunted them, they were sure to bring back one or two, at least, in the space of twenty-four hours. I shall soon have occasion to speak of their chace, and their weapons.

We quitted Paratounka and resumed our journey; twenty horses sufficed for ourselves and our baggage, which was not considerable, M. Kasloff having taken the precaution of sending a great part of it by water, as far as the ostrog of Koriaki. The river Avatscha has no tide, and is not navigable farther than this ostrog; and not at all indeed, except by small boats, called batts. The baidirs only serve to cross the bay of Avatscha, and can proceed no farther than the mouth of the river, where their lading is put into these batts, which, from the shallowness and rapidity of the water, are pushed forward with poles. It was in this manner our effects arrived at Koriaki.

As to ourselves, having crossed the river Paratounka at a shallow, and winded along several of its branches, we left it for a way that was woody and less level, but which afforded us better travelling; it was almost entirely in valleys, and we had only two mountains to climb. Our horses, notwithstanding their burthens, advanced very briskly. We had no reason to complain of the weather for a single moment; it was so fair, that I began to think the rigour of the climate had been exaggerated; but shortly after, experience too well convinced me of its truth, and in the sequel of my journey, I had every reason to accustom myself to the most piercing frosts, too happy when in the midst of ice and snow, that I had not to contend with the violence of whirlwinds and tempests.

We were about six or seven hours in going from Paratounka to Koriaki, which, as far as I could judge, is from thirty-eight to forty wersts. Scarcely arrived, we were obliged to take refuge in the house of the toyon, to shelter ourselves from the rain; he ceded his isba to M. Kasloff, and we spent the night there.

The ostrog of Koriaki is situated in the midst of a coppice wood, and upon the border of the river Avatscha, which becomes very narrow in this part. Five or six isbas, and twice, or at most three times the number of balagans, make up this village, which is similar to that of Paratounka, except that it is less, and has no parish church. I observed in general that ostrogs of so little consideration were not provided with a church.

The next day we mounted our horses and took the way to Natchikin, another ostrog in the Bolcheretsk route. We were to stop a few days in the neighbourhood for the sake of the baths, which M. Kasloff had constructed at his own expence, for the benefit and pleasure of the inhabitants, upon the hots springs that are found there, and which I shall presently describe. The way from Koriaki to Natchikin is tolerably commodious, and we crossed without difficulty all the little streams that fall from the mountains, at the foot of which we passed. About three-fourths of the way we met the Bolchaïa-reka[23]; from the site of its greatest breadth, which in this place is about ten or twelve yards, it appears to wind to a considerable extent to the north east; we journeyed on its bank for some time, till we came to a little mountain, which we were obliged to pass over in order to reach the village. A heavy rain which came on as we left Koriaki, ceased a few minutes after; but the wind having changed to the north-west, the heavens became obscured, and we had abundance of snow; we were about two-thirds of our way, and it continued till our arrival. I remarked that the snow already covered the mountains, even such as were lowest, upon which it described an equal line at a certain elevation, but that below them no traces of it were yet perceptible. We forded the Bolchaïa-reka, and found on the other side the ostrog of Natchikin, where I counted six or seven isbas and twenty balagans, similar to what I had seen before. We made no stay there, M. Kasloff thinking it proper to hasten immediately to the baths, to which I was inclined as much from curiosity as from necessity.

The snow had penetrated through my clothes, and in crossing the river, which was deep, I had made my legs and feet wet. I longed therefore to be able to change my dress, but when we came to the baths our baggage was not arrived. We proposed drying ourselves by walking about the environs, and observing the interesting objects which I expected to find there. I was charmed with every thing I saw, but the dampness of the place, added to that of our clothes, gave us such a chilliness that we quickly put an end to our walk. Upon our return we had a new source of regret and impatience. Unable either to dry ourselves or change our dress, our equipage not being arrived, to complete our misfortune, the place to which we had retired was the dampest we could have chosen, and though it seemed sufficiently sheltered, the wind penetrated on every side. M. Kasloff had recourse to the bath, which quickly restored him; but not daring to follow his example, I was obliged to wait the arrival of our baggage. The damp had penetrated to such a degree that I shivered during the whole night.

The next day I made a trial of these baths, and can say that none ever afforded me so much pleasure or so much benefit. But before I proceed, I must describe the source of these hot waters, and the building constructed for bathing.

They are two wersts to the north of the ostrog, and about a hundred yards from the bank of the Bolchaïa-reka, which it is necessary to cross a second time in order to arrive at the baths, on account of the elbow which the river describes below the village. A thick and continual vapour ascends from these waters, which fall in a rapid cascade from a rather steep declivity, three hundred yards from the place where the baths are erected. In their fall, which is in a direction east and west, they form a small stream of a foot and half deep, and six or seven feet wide. At a little distance from the Bolchaïa-reka, this stream is met by another, with which it pours itself into this river. At their conflux, which is about eight or nine hundred yards from the source, the water is so hot that it is not possible to keep the hand in it for half a minute.

M. Kasloff has been careful to erect his building on the most convenient spot, and where the temperature of the water is most moderate. It is constructed of wood, in the middle of a stream, and is in the proportion of sixteen feet long by eight wide. It is divided into two apartments, each of six or seven feet square, and as many high: the one which is nearest to the side of the spring, and under which the water is consequently warmer, is appropriated for bathing; the other serves for a dressing-room; and for this purpose there are wide benches above the level of the water; in the middle also a certain space is left to wash if we be disposed. There is one circumstance that renders these baths very agreeable, the warmth of the water communicates itself sufficiently to the dressing-room to prevent us from catching cold; and it penetrates the body to such a degree, as to be felt even for the space of an hour or two after we have left the bath.

We lodged near these baths in a kind of barns, covered with thatch, and whose timber work consisted of the trunks and branches of trees. We occupied two, which had been built on purpose for us, and in so short a time, that I knew not how to credit the report; but I had soon the conviction of my own eyes. That which was to the south of the stream, having been found too small and too damp, M. Kasloff ordered another of six or eight yards extent, to be built on the opposite side, where the soil was less swampy. It was the business of a day; in the evening it was finished, though an additional staircase had been cut out to form a communication between the barn and the bathing house, whose door was to the north.

Our habitations being insupportable during the night, on account of the cold, M. Kasloff resolved to quit them, four days after our arrival. We returned to the village to shelter ourselves with the toyon; but the attraction of the baths led us back every day, oftener twice than once, and we scarcely ever came away without bathing.

The various constructions which M. Kasloff ordered for the greater convenience of his establishment, detained us two days longer. Animated by a love of virtue and humanity, he enjoyed the pleasure of having procured these salutary and pleasant baths for his poor Kamtschadales. The uninformed state of their minds, or perhaps their indolence, would, without his succour, have deprived them of this benefit, notwithstanding their extreme confidence in these hot springs for the cure of a variety of diseases[24]. This made M. Kasloff desirous of ascertaining the properties of these waters; we agreed to analyse them, by means of a process which had been given him for this purpose. But before I speak of the result of our experiments, it is necessary to transcribe the process, in order the better to trace the mode we adopted.

"Water in general may contain,

"1. Fixed air; in that case it has a sharp and sourish taste, like lemonade, without sugar.

"2. Iron or copper; and then it has an astringent and disagreeable taste, like ink.

"3. Sulphur, or sulphurous vapours; and then it has a very nauseous taste, like a stale and rotten egg.

"4. Vitriolic, or marine, or alkaline salt.

"5. Earth,"

Fixed Air.

"To ascertain the fixed air, the taste is partly sufficient; but pour into the water some tincture of turnsol, and the water will become more or less red, in proportion to the quantity of fixed air it contains."

Iron.

"The iron may be known by means of the galnut and phlogisticated alkali; the galnut put into feruginous water, will change its colour to purple, or violet, or black; and the phlogisticated alkali will produce immediately Prussian blue."

Copper.

"Copper may be ascertained by means of the phlogisticated alkali or volatile alkali; the first turns the water to a brown red, and the second to a blue. The last mode is the surest, because the volatile alkali precipitates copper only, and not iron."

Sulphur.

"Sulphur and sulphurous vapours may be known by pouring, 1. nitrous acid into the water; if a yellowish or whitish sediment be formed by it, there is sulphur, and at the same time a sulphurous odour will be exhaled and evaporate. 2. By pouring some drops of a solution of corrosive sublimate; if it occasion a white sediment, the water contains only vapours of liver of sulphur; and if the sediment be black, the water contains sulphur only."

Vitriolic Salt.

"Water may contain vitriolic salts; that is salts resulting from the combination of the vitriolic acid with calcareous earth, iron, copper, or with an alkali. The vitriolic acid may be ascertained by pouring some drops of a solution of heavy earth; for then a sandy sediment will be formed, which will settle slowly at the bottom of the vessel."

Marine Salt.

"Water may contain marine salt, which may be ascertained by pouring into it some drops of a solution of silver; a white sediment will immediately be formed of the consistency of curdled milk, which will at last turn to a dark violet colour."

Fixed Alkali.

"Water may contain fixed alkali, which may be ascertained by pouring into it some drops of a solution of corrosive sublimate; when a reddish sediment will be formed."

Calcareous Earth.
