![§ 38. Further, the irregular colouring of animal bodies is often caused by the reception of various extraneous colouring matters into the body. This is observed almost generally in the lower animals, especially in the parasitic, when living on dif- ferent kinds of food ;' also locally, as the consequence of various medicines and poisons; thus the bones of men, beasts and birds, are more or less reddened by food of a red colour.’ The taking of rhubarb often tinges light parts yellow; hydrocyanic acid renders many organs bluish or greenish; nitrate of silver,’ quack medicines, of which the composition is unknown,’ and other medicines,* often render the skin blackish.

Finally, we oftentimes observe some peculiar colouring matter or pigment’ spontaneously produced in animal bodies, and colouring certain parts more or less completely; such is the case in jaundice, écterus, and in melanosis. In the former dis- ease there is formed in the body a yellow animal extractive or colouring matter, which has great similarity to the pigment of the bile, and tinges almost all the solid and fluid parts of the body more or less yellow and dusky, however, so that many of the systems assume a yellow colour more frequently than others.? Diseases of the liver, asthenic fevers, as the plague, the American yellow fever,” typhus fever, &c., are commonly attended with jaundice; the same also occurs in animals, but much less frequently. In melanoszs,’ on the contrary, a deep brown or more frequently a blackish tinted pigment is mor- bidly produced, which occurs sometimes generally, sometimes to a limited extent; in the former, it is either mingled with the particular excretions, as the urine, the perspiration, the](https://iiif.wellcomecollection.org/image/b33489166_0001_0050.jp2/full/800%2C/0/default.jpg)
