OSSEOUS TUMOURS. 19 



Symptoms. — Are those presented by the presence of any 

 obstruction in the nasal cavities, as difficult breathing, etc. 



Treatment. — Prompt removal of the offending growth, 

 when accessible, is in all instances to be effected by means 

 of the bone-saw and forceps. 



Cysts. — In connection with the false nostrils, enlarge- 

 ments — erroneously described by some as tumours — are 

 met with : they are rather small in size, and contain matter 

 of a cheesy appearance and consistency. 



Treatment. — The absorption of these [enlargements may 

 be accomplished in many cases by various applications; but 

 the best way is to make an opening with a lancet, and 

 allow the contents to escape, after which the cyst should be 

 injected with a weak astringent solution. 



Pharyngeal Polypi. — Polypi are occasionally met with in 

 the pharynx, and usually have a constricted base. 



Symptoms. — The irritation of the parts may possibly give 

 rise to a slight discharge from the nostrils j the breathing is 

 at times very difficult, and the animal will show symptoms 

 of sufifocation, will pull back on the halter, and perhaps 

 fall, after which he may rise, breathe heavily, and be all 

 right in a short time. 



Treatment. — Examine the throat: the mouth speculum 

 may advantageously be used in the examination. If the 

 polypus has a broad base, it had better be not interfered 

 with. If the base is constricted, you may cast the animal 

 and remove it with the ecraseur. The hsemorrhage is often 

 very excessive, and there is always danger of the blood 

 escaping into the larynx, and thus finding its way into the 

 lungs and causing death. It is very difficult to get at the 

 part, and unless all the conditions, as age of the animal, etc., 

 are favourable, it is advisable not to attempt an operation. 



Epistaxis : Bleeding from the Nose. — Bleeding from the 

 nose may occur as a symptom of various diseases, as
