Technology may sell its Boylston street land, 

 but only subject to the restrictions and en- 

 cumbrances of abutters established by the 

 grant of the land to the institute in 1861 by 

 the legislature. The institute will therefore 

 probably retain its present site for part of its 

 work.

DISCUSSION AND COBBESPONDENCE 



HAS THE WHITE MAN MORE CHROMOSOMES THAN 

 THE NEGRO? 



In a recent number of Science (May 15, 

 1914), Professor Michael F. Guyer complains 

 that in my recent book on " Heredity and 

 Sex " I have given an erroneous impression 

 concerning the relation of his work on human 

 spermatogenesis to that of Montgomery on the 

 same subject. Professor Guyer objects to my 

 statement that while Montgomery's account 

 confirms his own as to the number of the 

 chromosomes it " is in disagreement in regard 

 to the accessory." I think my statement is 

 correct, but in order that the reader may 

 judge for himseK, let me quote Montgomery's 

 own summing up : 



But Guyer concluded that the two allosomes [sex 

 chromosomes] always pass undivided to one spindle 

 pole in the primary spermatocytes, reaching then 

 only half of the secondary spermatocytes, and la 

 these dividing presumably equationally. He con- 

 sequently argued two classes of spermatozoa are 

 produced in equal numbers. . . . That is to say, he 

 overlooked the variability in behavior of the allo- 

 somes specially studied by me. 



After giving his reasons for thinking that 

 this variability in the behavior of the allo- 

 somes is a normal process, Montgomery con- 

 cluded that there would " be four classes of 

 spermatozoa and not simply the two classes 

 distinguished by Guyer" (p. 10). And in 

 another connection Montgomery writes 

 ... if there be only two classes of sperm, as Guyer 

 argues, and one kind of egg, this should result in 

 equal numbers of the sexes and not in the ratio 

 actually known. 



These comparisons that Montgomery has 

 himself made seem to more than justify my
