After reading McIver's monograph one feels that there is nothing more to be said on the subject; if anything, the discussion has been almost too prolonged. Part 1 deals with the etiology, pathology and clinical features of the various types of obstruction. In part 2 diagnosis and treatment are considered, whereas part 3 is devoted to an analysis of the interesting problem of the cause of death. The writer seems specially qualified to deal with the whole subject, not only because of his clinical interests but because of his pioneer work with Gamble on the chemical derangements associated with intestinal obstruction. The unsurpassed format of the Hoeber monographs is maintained with a profusion of excellent illustrations, charts and diagrams. The bibliography is thorough, and there is a good index.
