256 MEMOIRS OF A VETERINARY SURGEON. 
was very offensive. I had him six months under treatment, 
during which time I trephined him fifteen times ; but the 
discharge, which had nearly ceased when he left my place, 
increased after he had been at work for some time. As he 
was sent some distance from here, I could only occasionally 
hear of his progress. The discharge continued ; and, after 
a year or two, he died glandered. 
I once operated upon a small pony with a discharge from 
the off nostril, and found an abnormal growth within the 
frontal sinus, a polypus. This was removed, and the animal 
soon got completely well and continued so for years. 
I also assisted a neighbouring veterinary surgeon to operate 
upon the frontal sinus of a blood horse, which had had a 
discharge from the off nostril for a long time. The bone had 
become so thin and soft, that by pressing on the outside one 
might have passed the finger through the bone. The cavity 
was full of matter, and the lining membrane thickened. This 
case did not prove successful. 
I was requested by another veterinary surgeon to see a case 
of chronic nasal discharge he had under treatment. Much 
had been done, but all was of no avail. Careful examinations 
of the mouth were repeatedly made, but no diseased teeth could 
be discovered, although small portions of hay had been 
observed to pass from the nostrils along with the purulent 
discharge. He was destroyed, when it was found that his 
teeth were all sound, but there was a defective state of the 
palatine bone; a small aperture existed just at its junction 
with one of the furthermost molar teeth. This small opening 
led to a winding track between the fangs of two of the teeth, 
and ultimately was traceable into the maxillary cavity. 
Other cases I could enumerate, but it is unnecessary, 
I shall therefore proceed at once to record my observations 
respecting the nature and treatment of this disease. 
NASAL GLEET 
Is a term used to denote a protracted discharge from one or 
both nostrils. This affection may be dependent upon one of 
three causes, viz., fungoid growths in one or more of the 
cavities of the head ; injuries to, and diseased facial bones or 
teeth ; and, lastly, maltreated or neglected catarrh. 
All writers have from time immemorial considered it desir- 
able to divide and subdivide the affections that give rise to this 
discharge, and to class them under different heads, and very 
properly so, viz., into catarrh, influenza, nasal gleet, chronic 
glanders, subacute glanders, and acute glanders. But for my
