This is a small volume designed primarily as a guide for the treatment of diabetes for the general practitioner. It is a fairly complete summary of the practical treatment of diabetes illustrated by many examples of patients and diets. It is arranged primarily for local use and as such it should serve as a guide for the man in general practice. It is not as critical a study as a similar volume which came from Prague in 1932 from a group of younger men from Professor Pelnář's clinic and it does not conform altogether with the ideas in this country. The chapters on coma and complications are well written. The impression given, however, is one of a somewhat unnecessarily involved management of the patient.
