 $125,000 ; for a new organ in Finney Memorial 

 Chapel, $25,000 ; subscriptions toward the new 

 atMetic field, $14,300. A large number of 

 gifts, mostly anonymous, go to make up tbe 

 $125,000 for the new art building. 



Dr. Beverly Thomas Galloway, assistant 

 secretary of the Department of Agriculture 

 and previously chief of the Bureau of Plant 

 Industry, has been appointed by the trustees of 

 Cornell University to be director of the New 

 York State College of Agriculture. Dr. Gallo- 

 way takes the place which was vacated by the 

 resignation of Professor L. H. Bailey and 

 which has been filled this year by Professor 

 W. A. Stocking as acting director. 



At the University of Missouri, Dr. I. F. 

 Lewis, of the University of Wisconsin, has 

 been appointed professor of botany, and Pro- 

 fessor E. J. McCaustland, of the University 

 of Washington, dean of the engineering 

 faculty and director of the engineering experi- 

 ment station. 



Walter Collins O'Kane has been elected 

 professor of zoology and entomology at the 

 Ohio State University. He graduated from 

 the university in the class of 1897 and has 

 been connected with the New Hampshire sta- 

 tion for the past four years. 



At Cornell University, George A. Works has 

 been elected professor of rural education in 

 the college of agriculture, and David Lums- 

 den assistant professor of floriculture. 



Dr. Gertrude KIam, demonstrator in psy- 

 chology at Bryn Mawr College, has been made 

 an associate. 



Dr. Douglas McIntosh, associate professor 

 in McGill University, has been appointed 

 associate professor of chemistry and acting 

 head of the department in the newly estab- 

 lished University of British Columbia. 



DISCUSSION AND COBBESPONDENCE 

 A NOTE ON THE ACCESSORY CHROMOSOMES OF MAN 



In two recent publications in which Mont- 

 gomery's and my own observations on the 

 accessory chromosomes in man (negro) have 



been mentioned, the phraseology of the authors 

 would lead any one who had not read the 

 original papers to the conclusion that there 

 was a decided discrepancy in our results, 

 whereas just the reverse is true. Thus Morgan 

 in his book, " Heredity and Sex," after re- 

 marking on my account of the accessories 

 says (p. 245) : 



Montgomery has also studied the same problem, 

 but his account while confirming the number, is in 

 disagreement in regard to the accessory. 



And again Komhauser, in his " A Com- 

 parative Study of the Chromosomes in the 

 Spermatogenesis of Euchenopa Binotata, etc.," 

 Arch. f. Zellforsch., Bd. XII., No. 2, speaking 

 of cases in which " the a;-element is in the 

 form of two chromosomes in the male " as 

 found by Wilson in Syromasies, continues 

 (p. 280) : 



Guyer ('10) has reported a similar condition in 

 the spermatogenesis of man. This case, however, 

 ■would seem to need confirmation, for both Gutherz 

 ('12) and Montgomery ('12) have, in the main, 

 been unable to support Guyer 's contention. 



This last is certainly a surprising statement 

 for any one to make who has read Mont- 

 gomery's paper, as the following excerpts 

 from his " Human Spermatogenesis, Sperma- 

 tocytes and Spermiogenesis, A Study in In- 

 heritance," Jour. Acad. Nat. Sci. Phila., Vol. 

 XV., 2d Series, 1912, well attests. Speaking 

 of the chromosomes of the primary spermato- 

 cytes he says (p. 8) : 



I can confirm Guyer 's conclusion that there are 

 12, of which 10 are bivalent gemini, each dividing 

 in both maturation mitoses, and 2 univalent allo- 

 somes (accessory chromosomes) which divide only 

 once in the two maturation mitoses. Guyer 's view 

 is therefore probably correct that the number in 

 the spermatogonia must be 22 and not 24 as rea- 

 soned by Duesberg. 



There is a slight discrepancy in Mont- 

 gomery's and my account of the subsequent 

 behavior of the accessories but even here we 

 agree in the main, for speaking of the ordinary 

 behavior of the accessories Montgomery con- 

 tinues (p. 9) : 



This is the usual condition and the one discov- 

 ered by Guyer.
