This is the second issue of this journal that was introduced during the current year. This number contains three original articles. The first deals with the optical recording of heart sounds; the second discusses gallop rhythm from the same standpoint, and the third shows the effect that may be produced on the electrocardiogram by suspending the heart in saline solution.
A case is reported, with a discussion of a shifting cardiac rhythm in connection with Cheyne-Stokes' respiration. This is followed by a short discussion of the causes of cyanosis in Ayerza's disease. The remainder of the book is devoted to abstracts of articles from the current literature.
The journal is well printed on an excellent quality of paper, and the illustrations are remarkably clear. It is probable that Spanish is less widely read than it should be. Apparently realizing this fact, the editors have added to each of the articles
