The thirtieth edition of the International Medical Annual is a substantial book of 054 pages dealing with the literature of the past year. The arrangement, as is well known, is practically alphabetical, which facilitates reference although it necessitates a separation of closely related topics. The limited space given to each topic necessitates a very considerable amount of condensation, yet the reader will find in it the essential advances in medicine during the year 1911. It is illustrated by a number of excellent plates, several of them colored. To a large extent the articles appear to be reviews and not a mere collection of abstracts. This factor especially will recommend itself to the practicing physician who desires not only a bibliography, but a clear estimate of the treatments proposed.
