The History of Salt

It is an interesting fact that the gastric juice varies in different classes of animals, according to the food on which they subsist; thus in birds of prey as kites, hawks, and owls, it only acts on animal matter, and does not dissolve vegetables; in other birds, and in all animals feeding on grass, as oxen, sheep, and hares, it dissolves vegetable matter, as grass, but will not touch flesh of any kind.

An alkaline spring has just been discovered in Bunhill Row which possesses most of the constituents of Carlsbad water, but in a dilute degree. A tube well, 217 feet in depth, has been recently completed on the premises of Messrs. Le Grand and Sutcliff, artesian well engineers. From an analysis which has been made of the spring found in the chalk it appears to be soft water possessing the characteristics which are peculiar to the above-mentioned famous German Spa. The well, although artesian, is only so to a partial extent, and a pump of a novel construction raises the water from 128 feet, and delivers it at the surface.
