to bone : for the same relation which a spine bears to a bone, 

 is also borne by flesh to that which is like flesh, in animals 

 possessing bones and spines. The flesh can be divided in 

 every direction, and so is unlike sinews and veins, which 

 can only be divided in their length. The flesh disappears 

 in emaciated animals, giving place to veins and fibres. Those 

 animals which can obtain abundance of good food have fat 

 instead of flesh. 



2. Those that have much flesh have smaller veins and 

 redder blood, and their intestines and stomachs are small ; 

 but those which have large veins and dark blood, and large 

 intestines and great stomachs, have also less flesh, for those 

 that have fat flesh have small intestines. 



CHAPTER XIII. 



1. ADEPS and fat differ from each other, for fat is always 

 brittle, and coagulates upon cooling, but adeps is liquid, and 

 does not coagulate; and broths made from animals with 

 adeps do not thicken, as from the horse and hog, but that 

 made from animals with fat thickens, as from the sheep and 

 goat. These substances also differ in situation, for the 

 adeps is between the skin and the flesh ; but the fat only 

 exists upon the extremity of the flesh. In adipose animals 

 the omentum is adipose, in fat animals it is fatty : for the 

 animals with cutting teeth in both jaws are adipose, those 

 that have not cutting teeth in both jaws are fat. 



2. Of the viscera in some animals the liver is full of 

 adeps, as in the cartilaginous fishes, for oil is procured from 

 these during the process of decomposition, the cartilagi- 

 nous fish are particularly free from adeps on their flesh, 

 but the adeps is separated on the stomach. The fat also 

 of fishes is adipose, and does not coagulate ; and some 

 animals are furnished with adeps on the flesh, and others 

 apart from the flesh ; and those creatures in which the 

 adeps is not separated from the flesh have less of this 

 substance on the stomach and omentum, as the eel : for 

 these creatures have little fat on the omentum. In most 

 animals the adeps collects principally upon the abdomen, 

 especially in those which take little exercise. 



3. The brain of adipose animals is unctuous, as in swine ; 

 that of fatty animals is dry. Of all the viscera the kidneys
