30 THE HISTOET OF ANIMALS, [B. II. 



the anus ; and by the lower, the parts from hence down- 

 wards. In those animals which have feet the hind leg is 

 the lower part of the body in point of size ; and in those 

 without legs, the same relation is observed in their various 

 kinds of tails. Such is the nature of perfected animals, but 

 they differ in the development of their parts. Man in the 

 young state has the upper part of his body greater than the 

 lower ; but as he grows the proportion of his parts changes, 

 wherefore also he is the only animal which does not move in 

 the same way when young and when grown up, for at first 

 a child crawls like a four-footed animal. 



7. Some animals grow in the same proportion throughout,as 

 the dog others when they are first born have their upper 

 part proportionally less than the lower, but as they approach 

 maturity, the upper parts increase in size, as in the lophuri, 

 for in these animals the part from the hoof to the haunch never 

 grows after their birth. 



8. There is a great difference in the teeth of animals, both 

 among themselves and from the human type ; all viviparous 

 and sanguineous quadrupeds have teeth ; some have teeth in 

 both jaws, which others have not ; this is the first distinction. 

 Those which have horns do not possess teeth in both jaws, 

 for they have no front teeth in the upper jaw. There are 

 others, as the camel, which, though it has no horns, has not 

 teeth in the upper jaw. 



9. Some animals have tusks like the boar, others have not ; 

 some have pointed teeth, as the lion, panther, and dog ; the 

 teeth of others have an even surface, as the ox and the horse. 

 Animals with pointed teeth have their teeth fitting into each 

 other ; no animal has both tusks and horns, neither those 

 with pointed teeth nor any others. Most animals have their 

 front teeth sharp, and their hind teeth flat ; all the teeth of 

 the seal are sharp pointed, showing an approximation to the 

 race of fishes, for all fishes have pointed teeth. 



j 10. None of these genera have a double row of teeth. But, 

 if we may believe Ctesias, there are some which have this 

 peculiarity, for he mentions an Indian animal called marti- 

 chora, which had three rows of teeth in each jaw ; it is as 

 large and as rough as a lion, and has similar feet, but its 

 ears and face are like those of a man ; its eye is grey, and 

 its body red ; it has a tail like a land scorpion, in which there
