200 COMPARATIVE DENTAL ANATOMY 



prognathous. The teeth are macrodont, with 

 rather heavy prominent tubercles and cusps. The 

 biscuspids are large as compared with the molars, 

 — a Simian feature. In the Chinese the teeth are 

 large and white, the anterior teeth being obliquely 

 placed. The teeth of the Japanese are similar to 

 the Chinese, but smaller, as the race is small- 

 boned. The Eskimos have rather small teeth, 

 with a round arch, the third molars being often 

 reduced in size and sometimes wanting. The up- 

 per molars are often tritubercular. The Malays 

 have teeth like the Mongolians, but are much dis- 

 figured by betel-nut chewing and mutilating cus- 

 toms. 



The Indians of America are generally macro- 

 donts, the teeth being large, strong, and well set 

 in a round arch. There is considerable variety 

 exhibited among the divers races of North and 

 South America, large, medium, and small teeth 

 being all found. Deformities are not infrequent, 

 and fourth molars and third incisors sometimes 

 occur. The teeth are much worn with age, like 

 the teeth of all savage people who live on a coarse 

 diet. The Mound-builders had fine teeth, in a 

 round arch, which when not worn were large, yel- 

 low, and squarely set and coarsely made. The 

 ancient Aztecs had small arches and small, fine 

 teeth, but the Mexican peon of to-day has defec- 

 tive teeth owing to deficient nourishment and dis-
