The leg-_bones_ of oxen, after having been whitened by boiling them with quick-lime, are used in the manufacture of the handles of knives and forks, and for innumerable other purposes. This substance, when good, is nearly allied to ivory: but is easily distinguished by its porous nature, its coarse grain, and its wanting the beautiful white veins which are so conspicuous in ivory. Bones, after having been burnt or calcined, are used by the refiners of gold and silver. The _horns_ of oxen are used for many of the same purposes as bone. After having been softened by heat they are capable of being moulded into almost any shape. They are sometimes stained in such manner as to imitate tortoise-shell, and they are then used for the making of combs. By a peculiar process they are rendered semi-transparent, and, when formed into thin plates, are employed instead of glass for lanthorns. Horn was the first transparent substance that was ever used for lanthorns and windows. _Tallow_ is the fat of sheep and oxen, cleared of its fibrous parts by straining and other management. It is further improved and clarified by the addition of alum, and, in this state, is used for the making of candles. Tallow is also a chief ingredient in soap. From the feet of oxen is procured a kind of oil, called _Neats'-foot oil_, which is of great use in the preparing and softening of leather. The _blood_ is employed in the clarifying of sugar, and great quantities of it, during the late war, were exported from London to Sweden for this purpose. The skins of the intestines are used for beating gold leaf betwixt; and these, under the name of _gold-beaters' skin_, are afterwards considered efficacious as an adhesive plaster for healing small wounds. Of gold-beaters' skin the French manufacturers of toys sometimes construct little balloons for the amusement of children. A few years ago there was, in London, an exhibition of animals formed of this substance and inflated with air. 102. British cattle are considered preferable to the cattle of any other country in the world. Those called DEVONSHIRE CATTLE, which are distinguished by their mahogany colour and light yellow horns, are adjudged to be the best of any. They are much used in agricultural labours, being peculiarly fitted for draught both by their hardiness and activity. The _beef_ of this breed is peculiarly excellent. Their _skins_ are thin, but improve much in tanning; and the _tallow_ is of peculiarly good quality.
