436 EFFECTS OF IL\DIUM RADIATIONS ON WHITE MICE 



with absence of ovum cells. The testes and the epididymis of the 

 radiated mice of the present experiment appeared macroscopically and 

 histologically normal, with the presence of abundant spermatozoa. 

 Owing to the method adopted for the irradiation of the mice, the testes 

 were too far from the source of radiation, and too well protected by the 

 intervening tissue to be definitely affected by the rays.
