76 DISEASES OF POULTRY. 



disease of the lungs prol)al)ly caused by this fungus and 

 due to contagion. In certain establishments in Paris, 

 these men feed daily several thousands of pigeons, 

 filling their mouths with a mixture of water and grains, 

 then applying their own lips to the open l)ill of the 

 birds in order to blow down a portion of this mixture. 

 It is probable that they in this way become infected 

 with the spores of the aspergillus from diseased pig- 

 eons. Culture and inoculation experiments made with 

 the expectoration of the affected " crammers " confirm 

 this explanation. 



Treatment. — The appearance of this disease 

 among poultry or pigeons should be at once accepted 

 as a signal for thoroughly cleaning and disinfecting 

 the houses and appurtenances liable to be infected. 

 The diseased birds should also be isolated and treated 

 or killed. Medical treatment to the nodules in the 

 mouth has not been reported upon sufficiently to allow 

 of an opinion be'ug formed as to its efficacy. The 

 remedies to be tried are boric acid solution fifteen 

 grains to one ounce of water; sulphate of copper ten 

 to fifteen grains to the ounce; carbolic acid in two per 

 cent solution; flowers of sulphur to be applied in 

 powder. 



CROUPOUS ANGINA. 



A form of croupous angina has been described by 

 Rivolta and Delprato as affecting pullets and young 

 pigeons, and which they believe to be caused by flagel- 

 late infusoria. They have named this organism the 

 Monoccrcovwnas gallincc. This germ is a round or dis - 

 coid body of a pale tint, and from 14 to 25 micromilli- 

 meters (1-2000 to 1-1000 of an inch) in length by 

 5 to 7 micromillimeters (1-5000 to 1-3500 of an. inch)
