DISTBIBUTIOK OF THE FIBST AND 

 BEOOND THOUSANDS 



Table IS. gives the distribution on January 

 1, 1910, of the thousand leading scientific men 

 of the country and the gain or loss of each 

 state in a period of about four years. The 

 distribution of the second thousand is also 

 shown. In respect to the first thousand, the 

 main facts have already been considered in 

 connection with the men who have acquired 

 or lost places in the group. This table shows 

 in addition the changes which have occurred 

 as the result of men removing from one state 

 to another who have retained their places on 

 the list. Massachusetts, as has been noted, 

 gained 14 men owing to the fact that 43 of 

 the new men reside in that state, while but 

 29 were lost to it through death or through 

 dropping below the standard. In addition it 

 has gained seven men, the excess of those 

 having places on both lists who have moved 

 into the state above those who have left it. 

 Its total gain in scientific men of standing is 

 consequently 21, and it has 58.7 of these scien- 

 tific men per million of its population accord- 

 ing to the census of 1900, as compared with 

 51.3 about four years ago. The increase in 

 the number of scientific men is nearly 13 per 

 cent. This is an honorable record. It is 

 commonly assumed that Boston has yielded to 

 New York City the position of literary center 

 of the country, and if the facts were not 

 known the same assumption would probably be
