-Pereira.,In the "London Journal of Arts and Sciences," a publication which contains the specification of new patented inventions, we find the following description of a patent granted to George Philbrick Swinburne of Pimlico:- "The patentee commences his specification by stating that heretofore, in manufacturing gelatine, it has been usual (with one exception) to act on large pieces of hides or skins, and to employ acids and alkalies, together with mechanical and other processes, which occupy considerable time, and are likewise costly; in the executed case above referred to, it has been the practice to reduce the pieces of hide into the state of pulp in a paper machine, and then to employ blood to purify the product obtained. This invention consists in the following more simple mode of manufacturing gelatine. The patentee takes hides or skins, or parts thereof, as fresh and sweet as possible, and free from hair, and he reduces the whole into shavings of thin slices or films, by any suitable instrument; he soaks the shavings or films for about five or six hours in cold water, and then changes the same; he repeats such changing of the water two or three times each day, until no smell or taste is to be detected, either in the water on in the shavings, and then he removes the shavings from the water. If this product is intended for soup, it is dried on nets, and is then ready for use. If gelatine is to be extracted, the shavings, after the above soaking, are put into a suitable vessel, with a quantity of water, sufficient to cover them when pressed down, and they are subjected to a heat not exceeding boiling water. When dissolved, the gelatine is to be strained through linen or other fabric, subjected to slight pressure with the hands or otherwise, or the solution may be permitted to run off from the vessel without straining, by which means much of the gelatine will be separated from the fibrous matters. The product of gelatine thus obtained is run in thin films on to a smooth surface of slate, or other suitable material, to set; it is then removed on to nets to dry, and when dry it is cut up with an isinglass cuter or other suitable apparatus. The residue, dried or not, may be used for thickening soup, and other culinary purposes.,
