Excerpt from Introduction to the Analysis of Drugs and Medicines: An Elementary Handbook for the Beginner
The method for the proximate analysis of unknown drugs and medicinal chemicals and mixtures has not been dealt with in a general manner by any recent work in the English language, although a number of foreign treatises dealing with special classes of medicinal compounds or drug constituents have appeared within the last few years.
This neglect is no matter of wonder, as the majority of investigators are interested in the more scientific and economic problems dealing with the chemical constitution and possible methods of synthesis in the laboratory of the members of the particular class of bodies with which they are dealing, rather than in the methods of separating these from all the sorts of possible combinations in which they reach the consumer. Partial exceptions to this are the drug and chemical assays which are made for evaluation or standardization purposes, or with the object of detecting objectionable additions, and which generally have to do with known substances.
