has in the interior of the mouth fourteen teeth, adapted for 

 chewing, in addition to those which protrude ; in the male 

 these are curved inwards, but in the female they are straight, 

 and project outwards. The sea-mouse, 30 a fish which goes be- 

 fore the balaena, has no teeth at all, but in place of them, the 

 interior of the mouth is lined with bristles, as well as the tongue 

 and palate. Amocg the smaller land quadrupeds, the two 

 fore-teeth in each jaw are the longest. 



CHAP. 63. WOKDEEFXJIi CIRCUMSTANCES CONNECTED WITH THE 



TEETH. 



The other animals are born with 31 teeth, whereas man has 

 them only at the seventh 32 month after his birth. While 

 other 33 animals keep their teeth to the time of their death, 

 man, the lion, the beasts of burden, the dog, and the rumi- 

 nating animals, all change them ; the lion and the dog, how- 

 ever, change none 34 but the canine teeth. The canine tooth of 

 the wolf, on the right side, is held in high esteem as an amulet. 35 

 There is no animal that changes the maxillary teeth, which 

 stand beyond the canine teeth. With man, the last teeth, 

 which are known as the " genuini," or cheek teeth, 36 come 

 about the twentieth year, and with many men, and females as 

 well, so late even as the eightieth ; but this only in the case 

 of those who have not had them in their youth. It is a 

 well-known fact, that the teeth are sometimes shed in old age, 

 and replaced by others. Mucianus has stated that he, himself, 

 saw one Zocles, a native of Samothrace, who had a new set of 

 teeth when he was past his one hundred and fourth year. In 

 addition to these facts, in man males have more teeth than 

 females, 37 which is the case also in sheep, goats, and swine. 



30 See B. ix. c. 88. 



31 Very few other animals are born with teeth, hv their natural state. 

 Apes, dogs, and cats are not horn with teeth. 



32 From the fourth to the eighth month in reality, during which the 

 four central incisors appear. 



33 The only ones that do not change are those which have three molars 

 on each side of the jaw. 



34 This is erroneous : they change the incisors and molars as well. 



35 See B. xxviii. c. 78. 



26 By us known as the "wisdom" teeth. 



,7 This is not the fact : they have usually the same number, hut there 

 are exceptions on both sides. The same is also the case with sheep, goats, 

 and swine.
