68 THE HISTOET OF ANIMALS. B. in.] 



after them the oviparous sanguineous animals ; those which 

 are well disposed, either by nature or by health, have not a 

 great deal of blood, as in those that have just drank ; nor 

 a very little, as in those which are very fat. Pat animals 

 have pure blood, though the quantity is small ; as they be- 

 come more fat they lose a portion of their blood, for fat is 

 free from blood. Fat is not corruptible, but blood and the 

 parts that contain blood are very corruptible ; of these the 

 parts surrounding the bones are most corruptible. 



3. Man has the thinnest and purest blood, that of the ox 

 and ass is the thickest and blackest of all viviparous ani- 

 mals. The blood is thicker and blacker in the lower than iu 

 the upper part of animals. The blood palpitates in the veins 

 alike in all animals ; this alone of all the fluids exists in every 

 part of the body of living subjects, and as long only as they 

 are alive. The blood first of all exists in the heart of all 

 animals before it is distributed through the body. When de- 

 prived of their blood, or if the greater part escapes, they faint 

 away ; but when a very great deal is lost, they die. When 

 the blood becomes very much liquefied, illness ensues, for it 

 becomes like serum, and flows through in such a manner, 

 that some have perspired blood ; and when taken out of the 

 body, it does not coagulate into a mass, but into separate 

 and divided portions. 



4. In sleeping animals, the blood in the extremities 

 is diminished, so that it does not flow freely when they 

 are pricked. Blood is formed from serum, and fat from 

 blood. When the blood becomes diseased, hemorrhoids 

 are produced, either in the nose or anus, and a disease 

 called ixia. 1 When the blood becomes corrupted in the 

 body, pus is formed, and from pus a scab. The blood 

 in females differs from that of males, for it is more thick 

 and black in females of similar health and age. In the 

 whole of the body the quantity of blood is less in females, 

 but internally they are more full of blood. Of all females, 

 women have the most blood, and the catamenia are more 

 abundant in them than in other females. 



5. When this blood is diseased, it is called a flooding. 

 Women have a less share in other diseases ; but a few are 

 afflicted with ixia, and with hemorrhoids and bleeding
