exceptional daughter (the T, from the X-rayed 

 female) was fertile in a second mating with an 

 eosin-eyed miniatui'e-winged male (the first 

 mating was sterile) and produced one excep- 

 tional daughter (white-eyed and normal- 

 winged). Of the five exceptional males (F, 

 from the X-rayed female) two were proved to 

 be fertile. The exceptional female (F, from 

 the X-rayed female) proved fertile when mated 

 with an eosin-eyed miniature-winged male and 

 produced one exceptional daughter (F^ of the 

 X-rayed female). Since only one of the two 

 exceptional females was fertile more data is 

 required before it can be assumed that the ex- 

 ceptional females formed as a result of X-rays 

 applied to the egg are fertile and produce 

 further exceptions. 



The experiments described confirm my earlier 

 findings that X-rays may be made to afl'ect the 

 germ cells and show further that the effect pro- 

 duced on the first generation, so far as at pres- 

 ent investigated, is identical with primary non- 

 disjunction. 



The writer wishes to express his indebted- 

 ness to the Research Laboratory of the General 

 Electric Company for their continued interest 

 in this work, to Dr. T. H. Morgan and Dr. 

 C. B. Bridges for helpful criticism and sugges- 

 tions and to Mr. O. J. Irish for technical as- 

 sistance.
