her death she was engaged in studies directed 

 more especially to this difficult phase of 

 gametogenesis. 



She discovered in the Muscidffl that the 

 homologous chromosomes lie side by side in 

 each spermatogonia! and oogonial division, as 

 vcell as before synapsis. Even in somatic 

 division a similar pairing was found. In 

 Ceuthophilus one to three supernumerary 

 chromosomes were discovered, whose behavior 

 in rest and in growth stages indicated, she 

 thought, their probable relationship to the sex 

 chromosomes (1912). Previously, she has 

 found that the presence of supernumerary 

 chromosomes in Diabrotica led to a variable 

 number (with fixed limits however) of chro- 

 mosomes in different individuals of the same 

 species. 



In the regenerative processes in the hydroid, 

 Tuhularia, Miss Stevens found that the old 

 tissues become remodeled into the new with- 

 out undergoing any retrogressive changes, and 

 a similar condition was found in Planarians. 

 In Sagitta the true oviduct, previously over- 

 looked, was described and its development, 

 and that of the ovary also, were thoroughly 

 studied. 



Some interesting facts in regard to the color 

 of the parthenogenetic and sexual forms of 

 Aphids were recorded, but the study of the 

 inheritance of these colors was not brought 

 to completion, although certain possibilities 

 were indicated. Miss Stevens's experimental 

 work was much less extensive. It included 

 studies on the regeneration of hydroids and 

 planarians. She performed the delicate op- 

 eration of separating the centrosome from the 

 rest of the karyokinetic figure with the eggs 

 of the sea-urchin. The non-nucleated piece, 

 with a centrosome but without a nucleus, was 

 found not to divide further, confirming 

 Boveri's conclusion that the centrosome alone 

 is unable to bring about cell division. 



Miss Stevens's work is characterized by its 

 precision, and by a caution that seldom ven- 

 tures far from the immediate observation. 

 Her contributions are models of brevity — a 

 brevity amounting at times almost to meager- 

 ness. Empirically productive, philosophically 



she was careful to a degree that makes her 

 work appear at times wanting in that sort of 

 inspiration that utilizes the plain fact of dis- 

 covery for wider vision. She was a trained 

 expert in the modern sense — in the sense in 

 which biology has ceased to be a playground 

 for the amateur and a plaything for the 

 mystic. Her single-mindedness and devotion, 

 combined with keen powers of observation; 

 her thoughfulness and patience, united to a 

 well-balanced judgment, accounts, in part, for 

 her remarkable accomplishment.

THE SCHOOL OF JOUENALISM OF 

 COLUMBIA UNIVEBSITT 



Talcott Williams, director of the School of 

 Journalism in Columbia University on the 

 Pulitzer Foundation at the formal opening of 

 the school at Earl Hall, September 30, spoke 

 in substance as follows : 



The School of Journalism opens, within a 

 year of the death of Joseph Pulitzer whose 

 endowment rendered this training for the 

 newspaper man possible, with about a hundred 

 students. They represent 21 countries and 

 states, including China and New Zealand. 

 Less than half are from New York state. In 

 the first year one half are men who have had 

 newspaper experience and all these left wage- 

 earning positions to enter the school. One 

 fifth of those in the school hold college de- 

 grees, a proportion far larger than when law 

 and medical schools first opened. Of the 100 

 pupils entering, nine are women, a proportion 

 of women less than that which exists in jour- 

 nalism, taking all newspapers and periodicals. 

 Of the teaching force, 24 in number, 8 or one 

 third have had practical experience in jour- 

 nalism and four have given nearly all their 

 active lives to this calling. 



In America great changes are worked by 

 wide discussion. The first fruits of the 

 school are that before it opened, the news- 

 paper discussion for six months past, jointly 

 due to its great endowment and the action of 

 Columbia University in accepting it, had 

 proved public conviction of the need of train- 

 ing for newspaper men and the demand and
