cluding many applications for copies of my four-page leaflet on Warble, 
with requests sometimes for one copy, but in a large proportion for 
numbers for distribution, up to as many as a thousand. I have also

information from my previous reports on Warble Fly, and have had 
great pleasure in copies of this being accepted for distribution to the 
students at the Royal Veterinary College, the Royal Agricultural 
College, and other important centres of special work. 
The only additional recipe for destroying maggots in the warbles 
which has been brought forward (so far as I am aware) besides those 
which we—that is, those practically concerned in warble prevention— 
have known now for fourteen years as answering well for the purposes 
required, is the application of dry salt by rubbing it into the openings 
of the warble swellings. From the report of the Technical Instruction 
Committee of the Staffordshire County Council, bearing date August 
14th, I gather that the experimental application was only tried on an 
exceedingly small scale; but doubtless, as well as the long known 
treatment of dressing with brine, might prove serviceable. 
Also, consequently on the careful attention which I have endea-
