As it now stands, the book presents a synopsis of the Non Metals, an outline of Qualitative Analysis with analytical schemes for both simple salts and complex mixtures, tests for the Alkaloids, the principles of Volumetric Quantitative Analysis, a section on the three organic classes of chief physiological interest — the Carbo hydrates, the Proteids, and the Fats, with a brief description of Ferments and Fermentation. The clinical section of the book treats of the Blood, the Urine, the Sweat, the Saliva, the Gastric Fluid, the Pancreatic Fluid, the Intestinal Fluid, Bile, Milk, and Water.
