"Yes, it does! That is just the trouble. Therefore we are forced to set about getting some oil back into it; otherwise it would be so harsh and stiff that we could do nothing with it. So we put the thin layers of wool into these machines and carry them along to a spraying apparatus which sprays them evenly with oil. We use olive oil, but some other manufacturers prefer lard oil or oleine."

So also the organic compounds lactate of soda, lactate of lime, pneumate of soda, margarate of soda, stearate of soda, butyrate of soda, oleine, margarine, stearine, lecethine, glucose, inosite, plasmine, serine, peptones, etc., are found alike in the tissues and in the blood plasma.

This product is obtained by thickening water-glass with stearine, oleine, or any other easily saponifiable fat. As it takes but very little of the substances named to make an article closely resembling soap, of course the product is very cheap. There does not seem to be any limit to the amount of water in it; at least the author found in one kind of mineral soap from Berlin 58 per cent. of water.

Ox-tallow consists of seventy-six parts of stearine and twenty-four of oleine, out of one hundred parts. The horns of oxen are used for many purposes. The horn consists of two parts: an outward horny case, and an inward conical-shaped substance, somewhat intermediate between indurated hair and bone, called the fluid of the horn.

Butter, though counted as a pure fat, is in reality made up of at least six fatty principles, there being sixty-eight per cent of margarine and thirty per cent of oleine, the remainder being volatile compounds of fatty acids. In the best specimens of butter there is a slight amount of caseine, not over five per cent at most, though in poor there is much more.
