reach, liquids will probably prove the best treatment, 
otherwise I prefer to employ dry applications, such as 
various powders or soluble “conoids.” Some very 
efficacious powders for dusting into the ear are those 
consisting of—(a) Zinc oleate, 1; boracic acid, 5. 
(5) Ground starch, kaolin, and boracic acid in equal 
parts. (c) Salicylic acid, 1; tale powder, 20—and these

free to exert their soothing and very beneficial effect 
upon the tender ulcerated surfaces. 
It is inadvisable to probe about in the depths of the 
meatus except where it is absolutely essential, as in the 
preliminary cleansing process, and then it may only be

feelings of the dog. 
Strong or irritant dressings are to be condemned for 
use in the auditory meatus, as granulations seem par- 
ticularly liable to occur. This has been observed to 
follow the too frequent use of hydrogen peroxide as an 
ear lotion. If the irritation is intense, and the dog is 
seriously damaging its ear through violent shaking or
