Excerpt from Examinations of Drugs, Medicines, Chemicals: As to Their Purity and Adulteration In the following work I have not only given the methods Of testing the purity and adultera tions Of medicines, but also Of drugs in general, and Of chemicals and some articles Of food. Each subject is almost a branch Of the other, and a work Of this sort which neglected to combine the whole would seem imperfect. Some articles, which should have been considered, may have been Over looked, and it is almost impossible that such should not be the case.
