ing." As a rule, roaring comes on gradually, though it 

 can be developed quite suddenly, as sometimes happens 

 in '* intermittent roaring." This remark is of some 

 significance, because a horse might be passed as " sound," 

 and yet immediately afterwards make a noise. This has 

 happened on more than one occasion, and the professional 

 examiner sued for damages, but without any results. 

 For many years advanced roarers have been kept at 

 work through the use of a tube in the \vindpipe — trache- 

 otomy — but it is very necessary to remove the tube 

 daily or even tv/ice a day to clean it. There is another 

 operation now practised by the veterinary profession 

 for the removal of the roaring sound, and consists of 

 stripping the ventricle of the larynx. In some horses it is 

 successful, in others not so. The disease is, of course, 

 still in existence in any case, even if the sound dis- 

 appears. This operation may, in certain instances, 

 prove valuable, in others it may be the means of fraud, 

 or it may be useless. It is impossible for the author to 

 recommend its adoption in view of its doubtful utility. 

 Many people confuse roaring with another abnormal 

 condition of the wind spoken of as 



Broken Wind 



The last-named has no connection with the larynx, but 

 is closely associated with changes of a chronic character 

 in the lungs — emphysema — although scientific investiga- 

 tion has, up to the present, failed to yield any satisfactory 

 explanation of this trouble. 



A chronic cough is the most significant indication of 

 broken wind, but a fraudulent vendor has been known 

 to disguise this by the use of lard, shot, etc., given 

 internally immediately prior to sale. The breathing is 

 also abnormal, the expiratory portion of the respirations 

 being double — " double Hft." 



" Broken wind " is often associated with lesions of the
