Prolonged and Perplexing Fevers.

This monograph consists of two main parts. The first is a very good discussion of heat products and heat regulation that serves as an excellent background for a consideration of the factors in addition to disease that may give rise to elevated temperature. The variations of temperature in health are stressed, and the reader is cautioned against considering all "fever" as pathologic.

The second part of the book consists of a series of chapters on various obvious and obscure illnesses associated with fever. The most important subjects listed are tuberculosis, sepsis, both local and generalized, tumors, and the collagen diseases. Numerous case histories are used to illustrate salient points. This section was somewhat disappointing, since it did not give an orderly approach to diagnosis. The fact that practically all of the material deals with adults makes it less valuable for physicians working with children. The references are excellent.
