The last experiment (Table 8) was to determine the effect of 

 soaked cow peas upon the number of progeny. If seeds were 

 soaked for 5, 10 and 15 minute periods, progeny appeared at the 

 end of 40 days, and if soaked for 30 minutes offspring appeared it 

 the end of 41 days; but 1, 3, and 24 hour soakings gave no progeny. 

 No doubt this result is due to the fact that the larvae can not 

 live within seeds which through the soaking may have removed 

 vitamines, or other essentials for life. 



In carrying out the experiments above described the writer 

 was greatly assisted by Miss C. M. Seitz, a former student of this 

 department.
