53 THE HISTORY OF ANIMALS. [fi. Til. 



4. Numbness does not take place in those parts of tbef 

 body which contain no sinews. The sinews are most abund- 

 ant on the hands and feet, and on the ribs and shoulder- 

 blades, and round the neck and arms. All sanguineous 

 animals have sinews ; but in those which have not jointed 

 limbs, and are without feet and hands, the sinews are small 

 and inconspicuous, so that in fishes they are most distinct 

 near the fins. 



CHAPTER VI. 



1. THE fibres are between the sinews and the veins ; but 

 some of them are moistened with serum, and they extend 

 from the sinews to the veins, and from the veins to the 

 sinews. There is also another kind of fibre, which is pro- 

 duced in the blood of most, but not of all animals. When 

 this is extracted from the blood, it does not coagulate, but 

 if it is not taken out of the blood it coagulates. These 

 fibres are present in the blood of most animals, but not in 

 that of the stag, prox, 1 and bubalis, 2 and some others ; so 

 that their blood does not coagulate like that of other 

 animals : the blood of stags is very like that of hares ; 

 for in both of these coagulation takes place ; not firm, as 

 in other animals, but trembling, like that of milk, if no co- 

 agulating substance is put into it. The blood of the 

 bubalis coagulates more thickly, only a little less so than 

 that of sheep. This is the nature of veins, sinews, and 

 fibres. 



CHAPTER VII. 



1. THE bones of animals depend upon one bone, and are 

 connected with each other, like the veins ; and there is no 

 such thing as a separate bone. In all animals with bones 

 the spinal column is their origin. The spinal column is 

 made up of vertebra, and extends from the head to the hips. 

 All the vertebrae are perforated; the upper part of the 

 head is a bone joined to the last vertebra, and is called the 

 skull, the saw-like part is the suture. 



2. This is not alike in all animals, for the cranium of 

 some consists of a single bone, as in the dog ; in others it 

 is compound, as in the human subject. The female has
