Dipper's Animal Oil. For. name: German, Hirschhorngeist.

An empyreumatic oil obtained during the destructive distillation of bone, ivory, hair, wool, etc., and then separating the fetid oil from the other products, and purifying it by re-distillation from a mixture of the oil and four times its bulk of distilled water, and repeating this latter process until a perfectly colourless oil is produced. The chemical constitution of this substance is most complex; it contains at least all the following substances: Methylia, Ethylia, Tritylia, Tetrylia, and Amylia; Aniline, Pyridine, Picoline, Lutidine, Pyrrol, Benzol, and a mixture of several Nitriles.

Characters and Tests. - Dippel's Animal Oil is limpid, very liquid, of a specific gravity of 0.75, inflammable, of a disagreeable penetrating odour, and a taste, at first acrid, then bitter. It is very volatile, and usually white; but exposed to the light, it becomes yellow, then brownish, at last of a blackish-brown, and at the same time more thick; it is mis-cible with alcohol and ether in every proportion; with water, in a small quantity. To be assured that this oil is not adulterated, it suffices to let fall a drop on white paper and then expose it to the air; if the oil is pure, not a spot remains. To test the presence of any vegetable essential oil, as turpentine, etc, we mix it with double its volume of alcohol, shaking well, and then throw it on a filter moistened with spirits of wine; the animal oil remains on the filter, whilst the alcohol passes through, carrying with it the vegetable oil. Finally, to preserve this oil from the influence of the air and light, which changes the colour and consistence, it is necessary to keep it in black bottles, stopped with ground-glass stoppers and covered with prepared bladder, tied tight.
