Figure 11. Graphs showing the effects of injections of homol- 

 ogous cytost upon the weights of three cats. The weights of the 

 animals are shown as ordinates and the number of injections of 

 0.25 cc. of a 10% solution of homologous cytost as abscissae. These 

 injections were spaced four days apart. (From a paper read by the 

 author before Section D of the Brit. Assn. Adv. Sci., Sept. 9, 1930.) 



noted that when pregnant cats happened to receive 

 sublethal injections of cytost, they frequently aborted 

 or gave birth to dead or weakly kittens. This led to a 

 brief study of the effects of cytost upon pregnant cats 

 and their offspring.
