Abstract
American Journal of Science and Art, September.—The original articles are: On the formation of hail in the spray of the Yosemite Fall, by W. H. Brewer. The paper describes a visit paid to the fall in April last. The amount of water passing over the fall was estimated at 250 or 350 cubic feet a second, and the height is 1550 feet. In the spray, which stung the hands and faces of the visitors, hail or ice-pellets were found. “It will be noticed that at the time when this hail was observed, the sheet was in the full blaze of the sun from top to bottom…. The air near was of a temperature of 70°. Prof. Le Conte has suggested that perhaps the cooled air wiihin the sheet is somewhat compressed and condensed in the base of the fall, and when liberated just outside by its expansion, freezes a part of the spray.”
