Written in Spanish, this is an excellent exposition of glomerulonephritis in children. The frequency, etiology, pathology and symptomatology are discussed and illustrated by diagrams, charts and photomicrographs. Considerable space is given to the treatment, both medical and surgical. One feels that the author knows what he is talking about, as 155 case histories are given. The bibliography is complete for both the South American and the foreign literature. This is an interesting book that has an appeal to any physician, regardless of the language he speaks.
