Colonel Ash and his colleagues have done a noteworthy service to American medicine by producing this atlas of the pathology of tropical disease, since, as far as the reviewer knows, nothing approaching it in usefulness is readily available at a reasonable price. Short but authoritative discussions of the various diseases are followed by the plates, which include maps, photographs of patients, reproductions of roentgenograms and photographs of gross specimens and histologic sections. The reproductions are excellent, and the microscopic sections, many in color and of high magnification, really show what the reader wants to know. The diagrams of the life cycle of parasites are unexcelled. The book is well got up on fine paper, and there is an index. It is hard to restrict one's praise of this excellent compendium.
