 upon the young science, developed during 

 the time when he investigated the causes of 

 cretinism and the conditions determining 

 the growth of the skull. The similarities 

 between pathological forms of the skull 

 and those found among different races of 

 man probably led him to researches on the 

 variations of form of the human body. The 

 scope of his anthropological interests ex-

 gave to anthropological work, partieu-
