Observations and Experiments with 



Neurolymphomatosis 



and the Leukotic Diseases 



By Charles S. Gibbs 



The transmission of neurolymphomatosis through the egg, and of 

 the leukotic diseases by means of viruses has been known for some 

 time. This investigation was undertaken to determine some of the 

 methods of the transmission with a view toward making the control 

 measures now in operation more effective.
