CHAPTER III
ON THE GENERAL MODES OF ACTION OF THERAPEUTIC AGENTS INTRODUCED INTO THE STOMACH
Prop. I.—That the great majority of medicines must obtain entry into the blood, or internal fluids of the body, before their action can be manifested
Prop. II.—That the great majority of medicines are capable of solution in the gastric or intestinal secretions, and pass without material change, by a process of absorption, through the coats of the stomach and intestines, to enter the capillaries of the Portal system of veins
Prop. III.—That those medicines which are completely insoluble in water, and in the gastric and intestinal juices, cannot gain entrance into the circulation
Prop. IV.—That some few remedial agents act locally on the mucous surface, either before absorption, or without being absorbed at all. That they are chiefly as follow:—
Prop. V.—That the medicine, when in the blood, must permeate the mass of the circulation, so far as may be required to reach the parts on which it tends to act
Prop. VI.—That while in the blood, the medicine may undergo change, which in some cases may, in others may not, affect its influence. That these changes may be—
Prop. VII.—That a first class of medicines, called Hæmatics, act while in the blood, which they influence. That their action is permanent

Or, on the mode in which therapeutic agents introduced into the stomach produce their peculiar effects on the animal economy
.....
The first of these questions is the simplest, and may be answered from experience. We know that one medicine is a purgative, because it opens the bowels. We call another an alterative, because the manifestations of vital action are somewhat different after its use from what they were before. The last question is the most difficult to answer, because it involves the exact mode in which a medicine first behaves itself, so as to bring about its recognised operation.
Though the arrangements and theories of authors have generally taken into account all three of these questions, yet they have usually given greater prominence to one or other of them. And according to this their predominant idea, I will take the liberty of grouping them into three schools for the sake of convenience; considering, first, some theories and therapeutical arrangements which are based upon the ultimate effect of medicines; secondly, some that depend upon their local tendencies; and thirdly, some others that concern their mode of operation.
