sella turcica, indicating a condition of under-develop- 

 ment of the pituitary (fig. 39). Further, Byrom 

 Bramwell 1 has recently shown that infantilism of the 

 pancreas may be a cause of general (including sexual) 

 infantilism. I have lately seen such a case, in which 

 pancreatic insufficiency was established beyond doubt 

 by chemical examination of the faeces. 



At the present time, although we have no very 

 definite knowledge on this subject, it may be said that 

 it is hardly possible that genital under-development with 

 ateleiosis can be due to primary ovarian insufficiency 

 alone, in view of our experimental and clinical evidence 

 on this subject indeed, in such circumstances girls 

 are generally tall. Ateleiosis seems to be a condition 

 of general infantilism, in which the genital organs may 

 suffer together with the rest of the structures of the 

 body. 



Again, the foetal and infantile development of the 

 genitalia is apparently uninfluenced by thyroid insuf- 

 ficiency, for I have found that in the cretin the genital 

 organs may be perfectly developed although function- 

 less ; that is to say, there is no interference with the 

 primary development in fcetal life, nor is the growth of 

 the organs checked until puberty then, however, the 

 genitalia, although well-developed, remain functionless. 

 I shall describe the condition of cretinism more fully 

 presently (p. 157).
