The voyage of discovery, with fifteen ports of call, namely, medicine, biology, anatomy, physiology, pathology, pharmacology, cellular pathology, bacteriology, serology, surgery, stimulative therapy, endocrinology, the theory of constitution, psychoanalysis, personality and back again to medicine, is, in brief, the plan of Lóbel's book. It is a series of essays under the titles listed and it deals briefly with each of the important divisions of medicine.

It is scholarly without being prosy, entertaining without being superficial. Only one important error mars the book and that is one of translation involving confusion between the terms typhus and typhoid, a confusion that is readily enough understood by the reader who is familiar both with German and English and with typhus and typhoid.
