Women are still catching up to men in the Summer School, numerically, that is. But the rate is slowing down. A preliminary report, released yesterday by Summer School Registrar Stanley Leonard shows that of the 2865 who have filed final study lists, 1634 or 57.13 percent are men, 1230 or 42.87 percent are women. One individual is of "unknown" sex, the report says.

The total registration is an increase of 179 over last year and 706 over four years ago, 1953. The percentage of males is considerably less than 1953's 64.4 percent, but only slightly less than last year's 59.8 percent.

Of those registered, 435 come from Harvard College and Radcliffe with 436 from the University graduate schools.

Hans Kohn, professor of History at CCNY, again teaches the two largest courses, History S-134c, Intellectual History of Nineteenth Century Continental Europe, and Government s-178, The World in the Twentieth Century: A Survey of International Relations.
