Pro(/iiosis. Tn and of itself "pip" is not a serious matter. It 

 is, however, usually associated with other disorders of the res- 

 piratory system, which may be very serious. Regarding this 

 matter Salmon says: "The exaggerated idea prevalent as to the 

 dangerotis character of 'pii),' prohal)ly arises from its being asso- 

 ciated with serious diseases of the respiratory organs and from 

 the fatal results which follow the forcible tearing away of the 

 dried epithehum. leaving a bleeding and ulcerating surface." 



Canker. 



Membranes formed in diphtheritic roup are sometimes called 

 canker, hut there are frequently found cheesy patches on the 

 mucous membrane of the mouth or tongue which are not asso- 

 ciated with roup. These growths are frequently, at least, the 

 result of a traumatic injur}- to the meni])rane. Male birds fre- 

 duentlv have canker where the\- have been picked in the mouth 

 l)v other males when lighting. The growths arc made up almost 

 entireh- of pus germs. These growths shotdd ])ro])ably l)e 

 considered as suppurating wounds. An unhealthy condition of 

 the mucous memljrane of the mouth dtie to digestive disorders is 

 sometimes accompanied by spots of canker. 



A good treatment for canker is undiluted creolin a])i)lied with 

 a cotton swab. The swab should be held against each sore for 

 a short time. The whole surface of each ])atch should be 

 treated. Another good treatment is to wash the sores with hy- 

 drogen ])eroxide 1 ])art anil water 1 part. 



7 linish. 



This term is also sometimes incorrectly applied to the false 

 membranes of dijjhtheria but there are at least two cases of trtie 

 thrush on reconl. That is. in two ca^es microscopic examina- 

 tion ha.s .shown that the patches, which in both these cases were 

 in the lower part of the oesophagus and crop, were made up 

 of spores and filaments of the fungus Saccharomyccs albicans.
