chicken hatched, F-2 the second, etc. The descent on the paternal side may 

 be ascertained by comparing Tables 7 and 9. 



The 11 hens showing lesions of neurolymphomatosis in the ovaries and in 

 one or more ovules laid 83 eggs from which 45 chickens were hatched. Of these, 

 29 remained normal and 16 developed neurolymphomatosis. As nearly as 

 could be determined by histological study, the disease did not appear in any 

 of the chickens hatched from eggs laid before the infiltrations had appeared in 

 the ovaries of the hens. Nine of the hens, in which the disease did not reach the 

 ovaries, laid 121 eggs from which 85 normal chicks were hatched, and no cases 

 of neurolymphomatosis appeared during the eight months of the experiments.
