PREVENTION 8 1 



there are marked differences in both the morbid anatomy and 

 etiologj'. For a comparison of the lesions and specific bacteria 

 of these two diseases see infectious leukaemia. 



S "JO. Prevention. Pasteur introduced a preventive 

 inoculation or vaccine for this disease. Kitt has found that 

 the eggs of fowls unknown to this disease possessed a sub- 

 stance somewhat similar to antitoxin. He immunized fowls 

 by injecting them subcutaneously with from four to eight 

 cubic centimeters of the white of such eggs. While exceed- 

 ingly interesting this method does not seem practicable. 

 Good sanitary conditions, isolation of the well from the sick 

 fowls and thorough disinfection seems to be the most satis- 

 factory procedure. It is important not to introduce the 

 disease with newly purchased fowls or to expose health}' ones 

 to the disease either at or in transportation to various poultry 

 exhibits.
