 genital predisposition on the one hand, and on the other hand damaging of

 length of life of such individuals is mostly shortened, and 56 per cent, of the 

 cases investigated by Bartel died between the fourteenth and twenty-fifth 

 years of life. The status hypoplasticus is thus not entirely identical with 

 status lymphaticus, but also not with true infantilism, which will be described 

 in another chapter.
