This book of some thousand pages contains a vast amount of valuable and scholarly medical lore. Dr. Bauer has done a remarkable piece of work, and this second edition bears witness to its favorable reception. Dr. Bauer takes up first in various sections leading symptoms such as hemorrhages, backache, and disorders of general feelings, and then there follow chapters on leading signs pertaining first to general appearance and then to various systems of the body. Each section is followed by an excellent bibliography, and there are numerous pertinent illustrations. Under the chapter on the general appearance, for example, are considered such things as stature, obesity and leanness, endocrine and pseudoendocrine features, jaundice, cyanosis, and edema, each one being gone into in detail with numerous implications. One is constantly stimulated in looking over the book by the variety and depth of information therein contained.
