UNIVERSITY REGISTRATION STATISTICS. 



A COMPARISON of the enrolment at the 

 institutions indicated in the table for the 

 fall of 1905 with the figures for the pre- 

 vious year will show that on the whole the 

 gains in the different institutions are not so 

 marked as they have been in previous years ; 

 indeed, a number of prominent institutions 

 show a decrease in attendance compared 

 with 1904. Among these are the University 

 of California, Columbia, Harvard, Johns 

 Hopkins, Northwestern and Princeton. 

 The most consistent gains have been made 

 by the University of Pennsylvania, Syra-

 Illinois, Michigan and Ohio State in the 

 west. The most pleasing feature of the 

 development is the general desire all along 

 the line to advance the standard of require- 

 ments for entrance, particularly in the pro- 

 fessional schools, and in a considerable 

 number of institutions the decrease in regis- 

 tration may be attributed to this factor. 

 The daily press is still commenting upon 

 the growth of the western institutions and 

 calling attention to a loss in the number of 

 students from the west attending higher 

 institutions of learning in the east. As was 

 pointed out by the writer in an article on 

 the geographical distribution of the student 

 body at a number of American universi- 

 ties,^ there has in reality been no ap-
