An experience of some seventeen years as teachers in a professional school, where Chemistry is considered one of the foundation-stones upon which young men must build a technical education, has convinced the authors that the subject must be taught in a way that, while thoroughly scientific, is yet distinctly adapted to the ultimate uses of the students.
The professions of Pharmacy and Medicine are closely related, and their uses for Chemistry are very much alike. The members of these professions must understand the composition and chemical properties and possibilities of the whole materia medica, both inorganic and organic, in order safely to maintain the important trusts committed to them,--trusts involying the continued health and life of their fellow-men. The importance of thorough chemical knowledge for these related professions is now recognized in the fullest way in their official publication, the U. S. Pharmacopæia, the last edition of which has embodied throughout the most detailed and exact statements of the chemical nature, properties, and reactions of medicinal substances, together with methods of analysis or assay and tests for purity.
We have sought in the following pages to offer a text-book on Chemistry which should combine scientific accuracy and completeness with that special reference to the needs of the pharmaceutical and medical student, as well as those in active professional practice, which will make it of value for both study and reference. Compounds recognized in the U.S. Pharmacopæia are specially indicated, but they are not taken out of their proper position for such discussion.
A brief outline of Elementary Physics, much of which is absolutely essential for the understanding of chemical methods, forms Part I. The convenient division of the elements into Non-Metals
