NASAL GLEET. 17 



agents in the form of an exceedingly fine powder. There 

 is also a spray diffuser, by means of which various solutions 

 may be beneficially employed. Various medicinal agents 

 may also be employed in the form of vapour; the chief 

 difficulty in the treatment of nasal gleet being the situation 

 of the diseased structures, and their almost total inaccessi- 

 bility. AVhen the sinuses are filled with the accumulated pus, 

 and the bones are involved, medicinal agents are useless, 

 and the operation of trephining must be performed to allow 

 the escape of the pus. As a rule it is not difficult to 

 trephine ; in some cases the diseased bones are soft enough 

 to admit of being cut with a knife. After trephining, the 

 cavities should be syringed with a solution of carbolic acid 

 in tepid water ; give alteratives and tonics with a liberal 

 diet, and generally a cure can be effected. In cases where 

 the turbinated bones are affected, as a rule a cure cannot be 

 accomplished. If the trouble is due to the presence of a 

 carious tooth, it should be removed at once. There is a case 

 on record where a carious tooth made its way into the 

 frontal sinus. Balsam of copaiva is very useful in some 

 cases. Inoculation may be tried as a determining test as to 

 whether the case is glanders ; nasal gleet in a majority of 

 cases is an incurable disease. 



Abscess of the Turbinated Bones.— This disease may 

 cause nasal gleet. 



Causes. — ^ Abscess of the turbinated bones may be caused 

 by injuries, presence of foreign bodies, etc. 



Symptoms. — There will be a discharge of pus from the 

 nostrils, which may be increased in quantity by elevating 

 the head of the animal for a few moments, then suddenly 

 depressing it. 



Treatment. — Trephine, and allow what pus is present to 

 escape, then remove all diseased bone or touch with dilute 

 hydrochloric acid ; after-treatment should consist of weak
