Abstract
American Journal of Science, October.—The compressibility of colloids, with applications to the jelly theory of the ether, by C. Barus. Various colloids were compressed in capillary tubes with mercury terminals. A solution of gelatine or albumen in water was found to have a low compressibility, and a solution of india-rubber in ether was taken as a type of a highly compressible colloid. When the colloid was compressed by the mercury, the meniscus would occasionally give way, and a droplet of mercury be projected through the substance of the colloid to a distance of 12 cm or more. This has an interest ing application to the problem of the motion of material bodies through a solid ether. The mechanism of this motion is not yet explained, but there is probably a temporary liquefaction of the colloid in front, and a subsequent solidification behind the moving body.—Eolian origin of loess, by C. R. Keyes.
