In their school days, the authors were apparently impressed with the significance of pathognomonic signs. The result is this book, a fairly long, if not complete, collection of medical signs and tests, arranged in alphabetical order. In the appendix the material is classified under different headings, such as palpation, auscultation, percussion, laboratory and roentgenology, and partially according to organs and diseases. For ready reference purposes, the listing of any number of signs, as many as twenty, under one man's name, must unavoidably entail confusion. Some patriotic partiality has also been shown in crediting a number of Cubans with signs—in one case eleven—probably unknown outside their own immediate circle. The number of laboratory tests is pitifully small, and, strange to say, the most popular among them all, the Wassermann reaction, is not given. The spelling is careless, and the whole series of facies (over seventy) is misplaced under fascies.
