Abstract
MR. S. FUJIWHARA has recently published a second valuable memoir on the abnormal propagation of sound-waves in the atmosphere (Bull. Centr. Meteor. Observatory of Japan, vol. ii., 1916, pp. 1–82). As in his previous paper (NATURE, vol. xcii., 1914, p. 592), he ascribes the peculiarities investigated to variations of the air temperature and of the velocity and direction of the wind, and he concludes that the structure of the upper atmosphere may be inferred from the form of the region of audibility.
