HEREDITARY TRAITS. 211 



Another case, somewhat similar to that of Andrian and 

 his son, is found in a Burmese family, living at Ava, and 

 first described by Crawford in 1829. Shwe-Maong, the 

 head of the family, was about thirty years old. His whole 

 body was covered with silky hairs, which attained a length 

 of nearly five inches on the shoulders and spine. He had 

 four daughters, but only one of them resembled him. She 

 was living at Ava in 1855, and, according to the account 

 given by a British officer who saw her there, she had a son 

 who was hairy like his grandfather, Shwe-Maong. The 

 case of this family illustrates rather curiously the relation 

 between the hair and teeth. For Shwe-Maong retained his 

 milk-teeth till he was twenty years old (when he attained 

 puberty), and they were replaced by nine teeth only, five in 

 the upper and four in the lower jaw. Eight of these were 

 incisors, the ninth (in the upper jaw) being a canine tooth. 



Sex-digitism, or the possession of hands and feet with 

 six digits each, has occurred in several families as a sudden 

 variation from the normal formation, but after it has appeared 

 has usually been transmitted for several generations. In 

 the case of the Colburn family this peculiarity lasted for 

 four generations without interruption, and still reappears 

 occasionally. In a branch of a well-known Scotch family 

 sex-digitism after continuing for three or four generations 

 has apparently disappeared ; but it still frequently happens 

 that the edge of the hands on the side of the little finger i? 

 partially deformed. 



Hare-lip, albinism, halting, and other peculiarities, 

 commonly reappear for four or five generations, and are 

 seldom altogether eradicated in less than ten or twelve. 



from his portraits, had a good set of teeth), suggests a correlation 

 between hairiness and want of wit, which is at least likely to be re- 

 garded by those who ' wear his baldness while they're young ' as a 

 sound theory. ' Why, ' asks Antipholus of Syracuse, ' is Time such a 

 niggard of hair, being, as it is, so plentiful an excrement ? ' ' Because, ' 

 says Dromio of Syracuse, 'it is a blessing that he bestows on beasts ; 

 and what he hath scanted men in hair he hath given them in wit.'
