320 LAWS OF VAE1ATION. Chap. XXV. 



in those rare cases in which the hair has been renewed in old 

 age, for this has " usually been accompanied by a renewal of 

 the teeth." I have remarked in a former part of this volume 

 Miat the great reduction in the size of the tusks in domestic 

 boars probably stands in close relation with their diminished 

 bristles, due to a certain amount of protection ; and that the 

 reappearance of the tusks in boars, which have become feral 

 and are fully exposed to the weather, probably depends on the 

 reappearance of the bristles. I may add, though not strictly 

 connected with our present point, that an agriculturist 19 

 asserts that " pigs with little hair on their bodies are most 

 " liable to lose their tails, showing a weakness of the 

 " tegumental structure. It may be prevented by crossing 

 " with a more hairy breed." 



In the previous cases deficient hair, and teeth deficient in 

 number or size, are apparently connected. In the following 

 cases abnormally redundant hair, and teeth either deficient or 

 redundant, are likewise connected. Mr. Crawfurd 20 saw at 

 the Burmese Court a man, thirty years old, with his whole 

 body, except the hands and feet, covered with straight silky 

 hair, which on the shoulders and spine was five inches in 

 length. At birth the ears alone were covered. He did not 

 arrive at puberty, or shed his milk teeth, until twenty years 

 eld; and at this period he acquired five teeth in the upper jaw, 

 namely, four incisors and one canine, and four incisor teeth in 

 the lower jaw ; all the teeth were small. This man had a 

 daughter who was born with hair within her ears ; and the 

 hair soon extended over her body. When Captain Yule' 21 

 visited the Court, he found this girl grown up; and she 

 presented a strange appearance with even her nose densely 

 covered with soft hair. Like her father, she was furnished 

 with incisor teeth alone. The King had with difficulty 

 bribed a man to marry her, and of her two children, one, a 

 boy fourteen months old, had hair growing out of his ears, 

 with a beard and moustache. This strange peculiarity has, 

 therefore, been inherited for three generations, with the
