On each occasion Mr. H— put the patient under the in¬ 
fluence of chloroform before operating. The opening through 
the cornea was made with a " Beer’s knife/’ such as sur¬

THE OPERATION OF “ FIRING ” FOR ROARING. 
By J. G. Cattrall, M.R.C.V.S., London. 
In answer to Mr. E. Coleman Dray’s letter of inquiry that 
appeared in the Veterinarian of December last, relative to the 
new operation for roaring, and its effects, and which has not 
yet been answered through the medium of your pages, per¬ 
mit me to say in reply that the operation mainly consists 
in the application of the actual cautery by means of a flat

generally, that I have had recourse to the above remedy in 
very many cases of roaring, both as the result of protracted 
influenza, and arising from an hereditary predisposition, and

pleasure to contribute any little information I am able, tend¬

opinion is in accordance with that of Mr. E. C. Dray’s, 
namely, that your columns are the most fitting place for our 
professional discoveries and investigations to be recorded. 
But when some of our leading practitioners are the first to 
make a sporting paper the vehicle for their reports, I think 
that as members of a common profession we are justified in 
trying to suppress such a practice, which can only be accom¬ 
plished by writing to the same journal. In the months of 
June, July, and August of last summer, the subject relating 
to the new operation for the cure of roaring in horses con¬

west end of London, but more particularly among our cab 
proprietors. Indeed it was so much so, that it became 
almost a mania affecting these knights of the whip. Who-
