and the statutes framed and adopted. From 

 these statutes we learn that the objects of the 

 association are to be promoted by the appoint- 

 ment of committees charged with the consid- 

 eration and investigation of questions sub- 

 mitted by the council, by the publication of 

 the results of such investigations and by the 

 holding of conferences and congresses. It 

 was decided at the opening meeting that the 

 first international committees should be ap- 

 pointed for dealing with the questions of 

 nomenclature in mineral and organic chem- 

 istry, and with the unification of the modes 

 of stating physical constants. The next meet- 

 ing of the association is to be held in Berlin 

 on April 13, 1912, with Professor Ostwald as 

 president, and the 1913 meeting is to be held 

 in Great Britain.

DISCUSSION AND COSBESPONDENCE 



DOUBLE MATING OF SILK-WORM MOTHS 



In Science for May 19, 1911, Professor 

 Kellogg reports certain double mating experi- 

 ments with silk-worm moths, of which he in- 

 vites criticism. His account leaves one with 

 the general impression of a " perturbation in 

 the order of inheritance " due to the presence 

 of spermatozoa furnished by two different 

 males. Several possible explanations are sug- 

 gested by Kellogg, none of which however is 

 advocated. For example, he inquires : 



Do the eggs in double-mated females receive 

 more than one spermatozoon and are these sper- 

 matozoa often the representatives of both races 

 used in the double mating? Or can the egg be 

 in any way influenced by the mere presence in 

 the spermatheca of spermatozoa representing both 

 of a pair of allelomorphic heritable characters? 

 Can fluids carrying the spermatozoa have any in- 

 fluence during fertilization? Can the spermatozoa 

 of one type influence those of the other type dur- 

 ing their enforced companionship for several 

 hours or days in the female spermatheca!
