General or Sporadic Diseases.

smaller opening. The presence of tumours, thickening 

 of membranes and of the vocal chords, are also causes, 

 all of which may be present with the first-named. There 

 is no absolute cure. Operations have been attempted as 

 such, but they have brought no reputation to the pro- 

 moter. A variety of both roaring and whistling may also 

 be produced by causes resident within the nostrils. In 

 such cases we have removed tumours, which effected a 

 complete cure. When enlargement or ossification of 

 cartilages, &c, take place, the results are not so suc- 

 cessful. 



Grunting is due to similar causes, and is excited usually 

 by fright. There are temporary forms of this complaint, 

 which mat be traced to pleurisy, &c, &c. Care is, there- 

 fore, necessary for certain discrimination. 



Chronic Cough is the consequence of repeated attacks 

 of cold, sore throat, &c, as induced by hot and ill-venti- 

 lated stables, undue exposure, &c. It is hard, dry, and 

 persistent, amenable to no treatment, aggravated by care- 

 less feeding and repetition of the causes. Give linseed 

 mucilage with the food. Subcutaneous Injections, No. 7. 



Nasal Gleet is also one of the conditions which 

 remain as a result of constantly recur- 

 ring or neglected catarrh. It consists 

 of a chronic inflammation of the mem- 

 brane lining the sinuses of the head, by 

 which a constant discharge is secreted, 

 some of which is retained in the cavities, 

 becoming thick and offensive ; the 

 rest, overflowing, passes down the 

 nostrils, giving the animal a loathsome 

 appearance in the more advanced 

 cases. Some good may be accom- 

 plished by injecting astringent fluids, 

 but most cases call for trephining, or 

 opening the affected sinus, for which 

 operation a qualified veterinary surgeon 

 is indispensable. Recent cases may be successfully 

 treated by tonics and astringent injections. 



Spasm of the Diaphragm. — This is the result of 



Nasal Gleet.
