Excerpt from A Practical Treatise on Materia Medica and Therapeutics In describing the physiological action of drugs, two methods may be pursued: to present in chronological order a summary of the Opinions of various authorities on the subject in question; or, to condense in a connected description that view of the subject which seems to the author most consonant with all the facts. I have adapted the latter plan, from a conviction of its advantages for the student, and of its utility for the practitioner. The authorities which I have utilized in making up my opinions are placed at the end of each article, in order to avoid interruptions in the methodical descriptions.
