B. III.] THE HISTORY OF ANIMALS. 67 



are surrounded by the greatest quantity of acleps in all ani 

 mals ; that on the right side is always the least adipose ; 

 and let there be ever so much adeps, there is always a space 

 left between the kidneys. They are also the most fatty of 

 the viscera, and especially in sheep, for this animal some 

 times dies from the entire concealment of its kidneys in fat. 

 This excessive fat around the kidneys arises from good 

 pasture, as in the Leontine territory of Sicily ; wherefore 

 also in the evening they drive away the sheep which have 

 been feeding during the day, in order that they may take 

 less food. 



4. The fat around the pupil of the eye is common to all 

 animals ; for all have fat in this part, that possess it, and are 

 not hard-eyed. Fat animals, both male and female, are 

 more inclined to be barren, and all old animals become fat 

 more readily than young ones, especially when they increase 

 in depth, having obtained their proper width and length. 



CHAPTER XIV. 



1. THE following is the nature of the blood. This is most 

 essential and common to all sanguineous animals, and is not 

 Buperaclded, but exists in all animals that are not in a perish 

 ing condition. All the blood is in a vessel called the veins, 

 but in no other part of the body, except the heart. The 

 blood of all animals has no sense of touch, nor has the excre- 

 meutitious matter in the stomach; neither have the brain, nor 

 the marrow, any sensation of touch ; but wherever the flesh 

 is divided, the blood flows in the living subject, unless the 

 flesh is perishing. It is the nature of the blood to have a 

 sweet juice, as long as it is healthy and a red colour, and 

 that is bad which either by nature or disease is black. The 

 best kind of blood is neither very thick nor thin, unless it 

 is vitiated either by nature or disease. 



2. In living animals it is always warm and moist, but 

 when taken out of the animal the blood of all creatures co 

 agulates, except that of the stag and deer, and perhaps ome 

 others of the same nature. The blood of all other creatures 

 coagulates, unless the fibre is taken out of it. Bullock a 

 blood coagulates faster than that of any other animals. 

 Amongst sanguineous animals, those which are both inter- 

 Dally and externally viviparous, have the most blood, and
