This manual on diagnosis is well known and has gone through six editions since its appearance forty years ago. It is the type of textbook that contains so much information as to make reading difficult. Dealing essentially with the clinical side of diagnosis, the author takes the mechanistic view, correlating pathologic changes with diagnostic signs, which is, of course, good pedagogy. Such a work can in no way be substituted for the usual surgical textbook, but it makes a good reference volume. The entire subject of surgery is covered; there are no illustrations other than a few roentgenograms.
