PREVENTIVE AND CURATIVE TREATMENT OF CHRONIC 

 ROARING. 



In view of the increasing prevalence of chronic Roaring, its 

 tendency to occur in the most valuable horses, and the 

 serious and often rapid manner in which it leads to their 

 depreciation, only too frequently destroying their utility, 

 the necessity for adopting every means for preventing its 

 development, or, when it has become evident, removing the 

 causes upon which it depends, need not be insisted upon. 

 In fact, there are perhaps no questions connected with the 

 production, improvement, and utilization of horses, which 

 demand more serious examination and solution than those 

 relating to the prevention of this defect, or its removal 

 when its existence has become manifest. They have already 

 engaged the attention of veterinary surgeons and horsemen 

 for a long period, and the time has now arrived when, on 

 account of the great interests involved, no less than on 

 behalf of the noble creature himself, they should be seriously 

 discussed, and measures suggested for dealing with them in 

 a practical and satisfactory manner. 



These measures must be devised : (1) To the prevention of 

 Roaring, from a sanitary and medical point of view ; (2) To 

 the removal of the causes which give rise to it, either by 

 medical or surgical treatment. We will deal with them in 

 this order. 



1. Prevention, from a Sanitary Point of View. 



The prevention of chronic Roaring is of the utmost im- 

 portance, and should be the chief aim of those who have it
