This is a brief but concise monograph on a special field of dermatology, in which the present knowledge of mycologic diseases is well summarized. There is a general chapter in which are considered the morphology of fungi, microscopy and cultivation methods, immunity reactions, animal experimentation and the recent work on trichophytin. The special part gives the clinical details of the mycotic skin diseases and discusses their treatment. The colored reproductions of moulages and cultures are exceedingly well done. This volume should prove of great interest to all those engaged in mycologic work.
