UNIVERSITY REGISTRATION STATISTICS 

 The registration returns for November 

 1, 1910, of twenty-seven of the leading 

 universities of the country will be found 

 tabulated on the following page. Four 

 institutions exhibit a decrease in the grand 

 total enrollment this year, viz., Harvard, 

 Iowa, Indiana and Virginia, as against 

 four institutions in 1909, two in 1908 and 

 five in 1907. The largest gains in terms 

 of student units, including the summer 

 session attendance, but deducting summer 

 students who returned for work in the fall, 

 were registered by Columbia (with an un- 

 precedented increase of 1,279 students), 

 California (674), Minnesota (621), Wis- 

 consin (500), Chicago (396), Northwest- 

 ern (346) and Pennsylvania (330). Last 

 year there were also seven institutions that 

 showed a gain of over three hundred stu- 

 dents each, but only one (Columbia) that 

 registered an increase of over four hun- 

 dred students. Omitting the summer ses- 

 sion attendance, the largest gains have 

 been made by Columbia (796), Minnesota 

 (621), California (496), Wisconsin (407), 

 Northwestern (379), Nebraska (236) and 

 Chicago (231), seven universities exhibit- 

 ing an increase of over two hundred stu- 

 dents in the fall attendance, as against 

 eleven last year, and it will also be ob- 

 served that only one of the seven is an 

 eastern institution, whereas the eleven last 

 year were fairly evenly divided between 

 the east and the west. 



According to the figures for 1909, the 

 twenty-eight universities included in the 

 table ranked as follows: Columbia, Har- 

 vard, Chicago, Michigan, Cornell, Penn- 

 sylvania, Illinois, Minnesota, Wisconsin,
