This volume appears to be a good one of its kind, and to afford a fair, up-to-date, brief summary of medical practice. The author has evidently read extensively and carefully and gives the results in addition to facts from personal experience. We notice one or two slips, the most notable one being the rather extreme statement that two-thirds of mankind have tuberculosis and two-sevenths succumb to pulmonary tuberculosis and fully one-third to tuberculosis of some form, including affections of the intestines, bones, glands, etc. We were not aware that matters were quite so bad as that. Taken altogether, however, the work can be recommended as fully as meritorious as any other of similar scope and intent.
