This large volume is a glossary of medical terms and differs from the usual dictionary in that the definitions are more lengthy and descriptive. The medical words are classified into groups comprising medical diseases, medical phenomena, signs, reflexes, syndromes, and laboratory and surgical procedures. The authors use the proper names of the various terms in the great majority of instances and list these in alphabetical order in their respective groups. The book is divided into ten parts. The first part, which constitutes almost half of the volume, is a glossary of medical diseases. The remaining nine parts list the various phenomena, syndromes, signs, and so on, in a fashion similar to the first portion.
