personal equation have played any considerable part in de- 

 termining the differences observed. Moreover, the number of 

 cases is large enough to make it practically certain that typically 

 a decidedly smaller number of Purkinje cells is present in the 

 low grades of feeble-minded individuals. Here, then, we have 

 an anatomical deficiency as a basis of the observed deficiency 

 in motor coordination. To this should be added the fact that 

 many of the cells counted were atrophied and showed con- 

 solidation and degeneration of the nucleus to such an extent 

 that they could hardly have been of any functional value. Many
