The middle of the horn, after having been flattened by heat, and its transparency improved by oil, is split into thin layers, and forms a substitute for glass in lanterns of the commonest kind. The tip of the horns is used by makers of knife-handles and of the tops of whips, and for other similar purposes. The interior, or core of the horn, is boiled down in water. A large quantity of fat rises to the surface; this is put aside, and sold to the makers of yellow soap. The itself is used as a kind of glue, and is purchased by the cloth-draper for stiffening. The bony substance remaining behind is then sent to the mill, and, after having been ground down, is sold to farmers for manure. Besides these various purposes to which the different parts of the horn are applied, the clippings which arise in comb-making are sold to the farmer for manure, as well as the shavings which form the refuse of the lantern-makers. Horn, as is well known, is easily rendered soft and pliant in warm water; and by this peculiarity and its property of adhering like glue, large plates of horn can be made by cementing together the edges of small pieces rendered flat by a peculiar process, as a substitute for glass. Imitation of tortoise-shell can be given to horn by means of various metallic solutions. Horn, also, when softened, can be imprinted with any pattern, by means of dies. [Illustration] Diseases and their Remedies Under this head it is proposed to notice such diseases as are most common among cattle, together with their symptoms, and to suggest such treatment of the same as has been found in the practice of the author, in the main, effective. He is aware that much more space might have been appropriated to this head, as has been the case in other treatises of this class; but he doubts the propriety of multiplying words about diseases which are of very rare occurrence, deeming it more fitting to leave such instances exclusively to the intelligent consideration of the reliable veterinary practitioner. For convenience of reference, the diseases here noticed have been arranged in alphabetical order; the whole concluding with information as to two or three operations which cannot be uninteresting to, or unprofitable for, the reader. ABORTION. The cow is, more than any other animal, subject to abortion, or slinking, which takes place at different periods of pregnancy, from half of the usual time to the seventh, or almost to the eighth month. The symptoms of the approach of abortion, unless the breeder is very much among his stock, are not often perceived; or, if perceived, they are concealed by the person in charge, lest he should be accused of neglect or improper treatment.
