*THE POPULAR SCIENCE MONTHLY.*

organization which admits no colleges but those of the first rank. There are fifteen professors and instructors in other institutions. There are also thirteen principals, either of their own private schools or of endowed academies. This makes a list of 48; excluding ten duplicates, 38, or nearly 30 per cent., of the 128 teachers are of collegiate or principal rank.

This proportion of advanced rank holds good in the second decade, which contains 28 professors and teachers in colleges belonging to the Association of Collegiate Alumnæ. There are 21 professors, officers and instructors at other colleges and seven principals and preceptresses. Of the 56 just mentioned, excluding 11 duplicates, there are 45, or more than 29 per cent., of the 154 teachers of this decade, of collegiate or principal rank.

In the last decade it is not surprising to find that no graduate has yet attained to a professorship in a college belonging to the Association of Collegiate Alumnae. There are, however, 26 teachers in the Association of Collegiate Alumnæ colleges, one principal and 14 professors and teachers in other colleges. These 41 instructors make 13.48 per cent, of the 304 teachers of this decade.

Next to imparting knowledge Vassar alumnæ seem to be fond of acquiring it. After the teaching profession no occupation or pursuit enlists so many graduates as that of advanced study. In the first decade 35 have taken the degree of A.M.; three, that of S.B.; and two, that of Ph.D. The strictly professional degrees will be mentioned later. There are also three fellows and three who have done graduate work at universities without degrees. Excluding ten duplicates, 36 members of the first decade have done graduate work. This is 11.11 per cent, of the whole number for this period.

In the second decade 29 have taken the degree of A.M.; one, that of S.B.; one, Ph.M.; and six, Ph.D. There are also two fellows and six who have pursued advanced studies at universities without taking degrees. Excluding ten duplicates, 35 members of the second decade, or 9.26 per cent., have done graduate work at colleges and universities.

In the third decade 36 have thus far taken the degree of A.M.; thirteen, that of Ph.D.; there are eight fellows and 42 advanced students. The Ph.D. 's are accredited as follows: Yale, 4; Cornell, Chicago and Bryn Mawr, two each; University of Geneva (Switzerland), Columbia and Harvard, one each. The last is recorded, not granted, as Harvard University, almost alone among the colleges of this country, does not yet confer degrees upon women. Excluding 13 duplicates out of the foregoing 99 names, 86 alumnae of this decade, or 14.31 per cent., have done graduate work at American and foreign colleges and universities. In the class of '91, numbering but 36 members, there are five Ph.D.'s, almost one seventh of the whole.
