coast here is the secrete:
The brain has two skins to which correspond two on the testicles. Two bean-shaped growths are situated at the lower end of the skull; inside them is the brain, outside is the spine. Further: There are three arteries; one leads to the heart, the second to the lung, and the third to the liver. They distinguished between fatal diseases and less dangerous ones in the following words: If the skin of the spine is preserved, the marrow remains intact. He whose marrow becomes soft cannot beget children. Further: a skin formed in consequence of a wound on the lung is no real skin. The regulation concerning the 'sinew that shrinks' does not apply to birds, because they have no hollow of the hip. |
