Another manufacture of gelatinous substances is produced by the following process, from cod sounds, or other fishy matters capable of yielding gelatine: -These matters are reduced to shavings or thin films, soaked in water, subjected to the action of heat, and the gelatine strained or run off as above described. The patentee obtains a first, second, or third product of gelatine, which he forms into sheets, and when dry cuts up the same with an isinglass cutter. This manufacture of gelatine will be found highly useful as a cheap substitute for isinglass for clarifying liquids.,Inferior gelatine is used in large quantities by paper makers, straw-hat and silk manufacturers; but these parties generally purchase the skins, and prepare gelatine themselves.,Unlike isinglass, the shreds of gelatine, as already noticed, examined with the microscope, are seen to be composed of a transparent and perfectly homogeneous substance.
