When, some years ago, long hair was much more fashionable than it is at present, great numbers of young women in Germany suffered their hair to grow, and had it cut, from time to time, as a source of emolument. The notion that long hair is frequently cut from the heads of persons after they are dead is totally unfounded, since the uncertainty of such supply would alone render it impracticable. The hair that is used for men's wigs is almost wholly children's hair, no other being in general considered sufficiently fine for this purpose. The value of hair is from five to twelve shillings per ounce, according to the quality, length, or colour. Before it can be used it is well rubbed with dry sand, and afterwards boiled, to clean it. Such as is intended for wigs, if it do not curl naturally, is twisted round small earthenware cylinders, put into a vessel with sand, and baked in an oven, until it acquire this property. The most scarce and valuable kind of hair is that of flaxen colour. So great was formerly the demand for long hair, and so extravagant the price for which it was frequently sold, that a mode was invented of stretching it to nearly double its original length. This was effected by fastening the ends of the hair to the opposite sides of a vessel, placing a heavy weight across the middle, and applying heat underneath. As the heat softened the hair, the weight pressed it down, and extended it. But this project was found not to answer, as the hair lost all its quality, and could never be used but when mixed with other hair, and even then the fraud was discoverable by the stretched hair gradually shrinking nearly to its original length. In lawyers' and judges' wigs horse-hair and goats'-hair are frequently used, to give stiffness and form to the different parts. 16. _APES, BABOONS, and MONKEYS_ (Simia), _are all animals of hot climates, none of them except the Barbury ape_ (Simia inuus) _being ever found wild in Europe. They are distinguished by having four front teeth in each jaw, and all their feet formed like hands_. _Linnæus, although he has arranged these animals under one tribe, has characterised the apes by their entire want of tails; the_ baboons _by having short tails; and the_ monkeys _by having long ones. The tails of some of the monkeys, particularly those of South America, are so formed, that the animals are able to coil them round any object so firmly as to afford them a support in, apparently, the most perilous situations. Several of the monkeys have pouches within their cheeks, in which they collect their food previously to its being swallowed._
