THIS book comprises a series of forty schedules, each designed to occupy a three-hour practical period, intended for students following courses of training in pharmacognosy where a knowledge of microscopy of drugs, starches, textile fibres, etc., is required. Introductory chapters deal with such fundamental subjects as the technique of drawing of microscopic objects, micro-measurement, maceration, and micro-chemical tests. Then follow directions for the detailed examination of surgical dressings, fabrics and organized drugs. Finally are given methods and examples of quantitative analysis of mixed and adulterated powders, and an appendix of useful information.
