Boston, January 24, 1808.
By direction of the president of the Massachusetts medical society, I have the honour of transmitting to you the enclosed book, the pharmacopoeia of the said society; not without the hope of attracting a few moments of your high attention to the dangers, which result from the existing want of uniformity & of science, in the pharmaceutical language & pharmaceutical preparations, employed in the United States.
I have the honour to be, most respectfully, your humble servant
John C. Warren,
Rec. Secy M.M.S.
