The author limits the contents of this book to the determination of certain chemical constituents of the blood and urine which have some clinical significance, particularly in metabolic disturbances. Colorimetric methods for determining blood urea, nonprotein nitrogen, uric acid, creatinine, chlorides, sugar and cholesterol are described. A modification of Folin's method for estimating the total nitrogen of urine is added. The titratable acidity of the urine, a procedure of doubtful clinical importance, is also mentioned. The brief comments on the significance of the variations of the important chemical constituents of the blood, as well as the suggestions on the dietary management of nephritis and diabetes, are an added feature which many larger books on blood chemistry lack. The methods selected are reliable, are clearly stated, and require relatively small amounts of blood, and can be readily performed in a small laboratory. This volume should be a useful practical manual not
