Vintage Medical Pharmacy Book "The Pharmacopeia of the United popular States of America. Ninth Decennial Revision" 1916 Drug Formula Book Antique

1916 Apothecary Drug Formula book, "The Pharmacopeia of the United States of America. Ninth Decennial Revision." Hardback, 728 pages. Phar·ma·co·pe·ia was created from two Greek words: pharmakon (medicine or charm) and poiein (to make). Very interesting book. Zoom in on the formulas shown to get an idea.
Condition is very good, it is a little soiled, has some pages with creases, edgewear popular to cover (see photos). I believe this is a first edition.
