The authors, one of whom has been trained as a clinical pathologist and bacteriologist, present here a rather uneven novel concerning the daughter of a New York physician who marries a surgeon and herself becomes a laboratory technician, studies nursing and after having once left her husband comes back to him again. The motif is the natural jealousy of doctors' wives of the time spent on patients and particularly those of the fair (in the sense of the "beautiful") sex. The authors have apparently had sufficient contact with hospitals and modern medicine to lend to their novel, in the majority of instances, a highly realistic tone. Perhaps one should not quarrel too greatly with the psychology of what is meant to be lively and interesting rather than instructive and stimulating. No doubt any one connected with the medical profession will find this novel interesting.
