276 A MANUAL OF DENTAL ANATOMY. 



of teeth, for examples have just been given of absence of 

 hair and absence of teeth ; and, on the other hand, redund- 

 ance of hair has in several cases been accompanied by 

 absence of teeth. 



Thus, in the case of the now famous hairy family of 

 Burmah, the peculiarity of silky hair being developed over 

 the face was transmitted to a third generation, and in each 

 case the teeth were very deficient in number. A year or 

 two ago a hairy man and his son, said to have come from 

 the interior of Russia, were exhibited in London, and they 

 were also almost toothless.^) 



A good many years ago a hairy woman (Julia Pastrana) 

 was exhibited in London, of whom it has commonly been 

 reported that she had an extensive number of teeth. Certain 

 it is that her mouth was very prominent, and that she was 

 described as " dog-faced " and " pig-faced," but models have 

 been presented to the Odontological Society by Mr. Hepburn y 

 which are indisputably known to be models of her mouth, 

 and these do not show any excessive number of teeth. The 

 teeth, at least such of them as can be seen, are enormously 

 large, but the mouth is affected with general hypertrophy 

 of the gums and alveolar processes to such a degree, that 

 only a few of the teeth can be made out. 



But this does not make her case the less interesting to 

 the odontologist, for in the huge teeth, the enormous palilla? 

 of the gum, and the redundant hairs on the face, we have 

 evidence of a disposition to hypertrophies of the integument 

 affecting in different places the different tegumentary appen- 

 dages which happen to be there. And that the teeth are 



( a ) The man's mouth exemplified the dependence of the growth of the 

 jaw upon the presence of teeth. Ordinarily the increase in size between 

 childhood and adult age takes place by a backward elongation, which 

 allows for the successive development and eruption of the molars behind 

 the space occupied by the temporary teeth. But this man never had any 

 true molars, and no such backward elongation of the jaw had ever taken 

 place, so that, though he was a full-sized man, his jaw was no larger than 

 a child's.
