 -will receive $14,845 by the will of Norman B. 

 Bayley. 



The new master of Magdalene College, 

 Cambridge, Mr. A. C. Benson, has established 

 a Charles Kingsley lectureship in natural sci- 

 ence in the college with an income of £150. 



A school of applied social sciences will be 

 opened at Western Reserve University, at the 

 beginning of the next academic year. It will 

 be a graduate school with a two-year course, 

 in which supervised field work will be an es- 

 sential part of the plan. 



At the University of Cambridge the pro- 

 posed grace relating to the admission of wo- 

 men to the first and second M.B. examinations 

 and the examination in architectural studies 

 has been withdrawn, in order that reports on 

 the subjects may be presented to the senate by 

 the boards concerned. 



Mr. J. H. Hill has_been appointed professor 

 of mathematics at the Ohio Northern Univer- 

 sity. 



B. L. Daugherty has been appointed pro- 

 fessor of hydraulic engineering at Rensselaer 

 Bolytechnic Institute. He has for the past six 

 years been assistant professor of hydraulics in 

 Sibley College, Cornell University. He suc- 

 ceeds at Rensselaer Brofessor Lewis B. Moody 

 who has gone into private practise. Brofessor 

 Daugherty is the author of " Hydraulic Tur- 

 bines," " Centrifugal Bumps " and " Hydraul- 

 ics." He graduated from Leland Stanford 

 University in 1909 and was an instructor in 

 experimental engineering there the following 

 year. 



The following appointments have been made

DISCUSSION AND CORRESPONDENCE 



BEES AND MENDELISM 



Some confusion of thought as regards Men- 

 delian expectations is apparent in Mr. Quinn's 

 article 1 dealing with his interesting observa- 

 tions on the inheritance of body color in 

 crosses of Italian with Caucasian bees. Mr. 

 Quinn considers that his observations are not 

 in accord with those of Newell because the 

 latter concluded that "the production of an 

 Bj (heterozygous) drone seems to be an im- 

 possibility and this, in turn, makes the pro- 

 duction of a strict B„ generation look like an- 

 other impossibility." But Quinn reports ob- 

 taining a typical 1:2:1 ratio of pure yellow : 

 heterozygous yellow: pure gray queens in F„, 

 which he considers evidence that the drones as 

 well as the queens of the Bj generation are 

 heterozygotes. This would indeed be true if a 

 single Fj queen mated with a single drone gave 

 the result stated. But Quinn does not so re- 

 port the facts. His statement apparently ap- 

 plies to the F 2 queens considered collectively, 

 not to those produced by a single F, mother. 

 If, as both Newell and Quinn suppose, all F t 

 queens are heterozygotes and produce equal 

 numbers of I and C gametes, and if they are 

 mated some with pure I and others with pure 

 C drones, then the expectation as regards their 

 female offspring is that actually observed by 

 Quinn. For a mating with a pure I drone 

 should produce 1 II + 1 IC zygotes; and a 

 mating with a pure C drone should produce 

 1 IC -f- 1 CO zygotes ; and if the two kinds of 

 matings are equally productive, their com- 

 bined result would be 1 II -f 2 IC + 1 CC, as 

 reported by Quinn. It is therefore unneces-
