DISCUSSION 



Dr. Clarke: Is there any information available on the effects of carbon monoxide 

 or azide on neutron induced spectrum in Drosophila. whether used before or after 

 treatment?

 contamination to investigate this question. 



Professor White : I should just like to comment that from the recent work of Gall 

 at the University of Minnesota it would appear that the chromosomes in the spermatid
