but man grows them six months after birth, All the ^p"„'/J^,/j 

 rest keep their teeth permanently, but man, the lion, 

 the beasts of burden,dogs and ruminant animals shed 

 them ; with the Hon and dog however tliis only applies 

 to those called dog-teeth." The right dog-tooth of a 

 wolf is held to be valuable as an amulet.'' No 

 animal sheds its maxillary teeth, the ones next to 

 the dog-teeth. In man those called wisdom-teeth 

 grow latest, at about the age of twenty, and in many 

 cases even at eighty, with females as well, but only in 

 the case of persons who did not grow them in youth. 

 It is certain that in old age they fall out and then 

 grow again. Mucianus has stated that he saw 

 a Samothracian named Zocles who grew a new 

 set of teeth when 140 years old. For the rest, 

 males have more teeth than females in the case of 

 man, ox, goat and pig." Timarchus son of Nicocles 

 at Paphos had two rows of maxillaries ; his brother 

 did not shed his front teeth, and consequently wore 

 them down. There is a case of a person even growing 

 a tooth in the palate. Any of the dog teeth lost 

 by some accident never grow again. With all other 

 species the teeth get red in old age, but in the horse 

 alone they become whiter. 



LXIV. In beasts of burden the teeth are a sign ^g^Jl. 

 of their age. A horse has forty teeth ; when two- ammau. 

 and-a-half years old it loses two front ones in each 

 jaw, and in the following year the same number of 

 the teeth next these, when they are replaced by 

 those called grinders ; at the beginning of its fifth 

 year it looses two teeth, which grow again in its 

 sixth year ; in its seventh year it has all of its second 

 teeth and also its permanent ones. A horse 

 previously gelt does not shed its teeth." The ass
