 of narkosis by means of a comparatively trifling quantity 

 of the aniBsthetic, and with quicker recovery from its 

 effects, than when several ounces are slowly inhaled ; so 

 that there is a saving in time and in the drug, and an 

 abbreviation of the inconvenience and suffering- experienced 

 by the animal operated upon. 



In carrying out the operations on the large number of 

 horses submitted to surgical treatment for Roaring, I must 

 not fail to acknowledge the great skill, wonderful dexterity, 

 and unfaltering enthusiasm displayed by Mr. F. Raymond, 

 F.R.C.V.S., Army Veterinary Department, who acted under 

 my direction. To him the success of the operative procedure 

 on these horses is largely due ; his perseverance, judgment, 

 and expertness deserve the highest praise, and have elicited 

 my warm admiration. 



As time elapses the operation may be still more perfected 

 — though I think this is scarcely possible — and its remote 

 results will be more accurately noted. The experience now 

 gained will doubtless be added to, and Roaring will conse- 

 quently become more readily removable by operation, easily 

 and safely practised, by every veterinary surgeon ; but I trust 

 the greater advantages to be derived from the preventive
