movement of the population westward, a cor- 

 relation between density of population and per- 

 centage of noted men now resident in various 

 states should give about the same coefficient 

 as the corresponding one based on the place of 

 birth. If the correlation based on residence 

 shows an Increase over that based on birthplace, 

 a tendency of noted men to gather in densely 

 populated states is indicated ; a decrease would 

 indicate the reverse tendency. Now, the cor- 

 relation for residence and density when forty- 

 six states are taken is 0.18 ±0.10; with the 

 twenty-nine older states it is 0.64 ±: 0.07. 

 These results are on the basis of Who's Who 

 in America. Dr. Cattell's list gives a coefficient 

 of 0.71 it 0.06. Compared with correspond- 

 ing correlations on the basis of birthplace, these 

 coefficients show a decrease of 74 7^ and 11^, 

 and an increase of 20% respectively. A de- 

 crease, as shown above, indicates movement of 

 able men toward sparsely settled states in ex- 

 cess of the movement of the genera! population, 

 while the increase indicates the reverse. It may 

 be the case, however, that the decided figure 

 given in the first instance, where forty-six 

 states are dealt with, is due to the fact that in 

 the very new states immigrants rise without
