198 The Management and Diseases of the Dog. 
“In that form of the disease to which I specially refer—. 
where a polypoid excrescence follows and accompanies the. 
uluceration of caries—if a period of three weeks or a month: 
be allowed to elapse between the first exhibition of the... 
discharge and the examination of the meatus, it may be 
found that the vegetation has attained a considerable size,. 
and the discharge has become more and more profuse and 
bloody. The extent of bloody discharge and its feetidity,. 
will much depend on the nature of the tumour, and the 
original tissue of the meatus that may beaffected. Ifthere 
is much blood mixed up with the discharge, then in all 
likelihood there will exist a soft and vascular polypus, pro= 
duced from the more vital fibro-cartilaginous structures of 
the meatus; and should the smell be great, and the 
discharge little tinged with blood, then the original 
disease will be found to exist in the osseous portion 
of the tube, and the polypus, if it does exist, will be of the - 
chondromatous or cartilaginous kind.” - 
Treatment.—This should consist, if the growth is in the 
outer half of the meatus, and within reach, in removal by 
torsion, ligature, or excision, and the subsequent application 
of caustic. If near to the tympanum, such an operation 
would be attended with danger, and the potassa cum calce, © 
as recommended in human surgery, is best adapted to the 
case. The injection ot mild astringents should, in the’ 
course of a few days, follow either measure. 
DEAFNESS. 
Deafness in dogs may be congenital, * or result from 
obstruction in the auditory Passage, caused by disease, 
injury, the lodgment of water, or it may result from 
* T recently examined a white terrier, belonging to a clergyman, in 
which the sense of hearing had never been recognised—being, in fact, 
“angenital, and the animal was destroyed in consequence.
