On account of the rigid selection of the ovaries reported in Table 15 it would 

 appear that neurolymphomatous infiltration into the ovaries and ovules was 

 common, and it may be that it is; but infiltrated ovaries and ovules certainly 

 were not as easy to find as the data in this table would indicate. It should be 

 borne in mind that the birds were carefully selected for these experiments from 

 a greater number that were rejected, and then no ovary was studied histologi- 

 cally unless it appeared to be infiltrated on macroscopic examination. 



On comparing the results of the histological studies with the transmission 

 experiments, it was found that 13 of the hens, M-355, M-553, M-1389, H-1492,
