Oleum animale

These interesting substances, closely related to the vegetable alkaloids, as well as to some of the alkaloids produced during purtrefactive decomposition of animal matters, were first discovered in 1846, as constituents of oil of Dippel = oleum animale = oleum cornu cervi = bone-oil, an oil produced during the dry distillation of bones, horns, etc., and as a by-product in the manufacture of ammoniacal compounds from those sources. They also occur in coal-tar, naphtha, and in commercial ammonia, methylic spirit, and fusel oil.
