1 Liquid volatile alkaloids, alkaloids of hemlock, nicotine, piturie, sparteine, aniline.

2 The opium group of alkaloids.

3 The strychnine or tetanic group of alkaloids—strychnine, brucine, igasurine.

4 The aconite group of alkaloids.

5 The mydriatic group of alkaloids—atropine, hyoscyamine, solanin, cytisine.

6 The alkaloids of the veratrines.

7 Physostigmine.

8 Pilocarpine.

9 Taxine.

10 Curarine.

11 Colchicin.

12 Muscarine and the active principles of certain fungi.

There would, perhaps, have been an advantage in arranging several of the individual members somewhat differently—e.g., a group might be made of poisons which, like pilocarpine and muscarine, are antagonistic to atropine; and another group suggests itself, the physiological action of which is the opposite of the strychnos class; solanin (although classed as a mydriatic, and put near to atropine) has much of the nature of a glucoside, and the same may be said of colchicin; so that, if the classification were made solely on chemical grounds, solanin would have followed colchicin, and thus have marked the transition from the alkaloids to the glucosides.
