EXOSTOSIS OR OSTEOSARCOMA IN THE BONES 
OF THE FACE. 
Mr, Harry Daws. 
Fortunately for the animal, as well as the veterinary sur¬ 
geon, this disease is not very common among us. Mr. Percivall 
related one case in the last page of his first volume ; and I have 
had an opportunity of witnessing the progress and treatment of 
this odious malady from its commencement to its termination. 
The horse was attended by a member of the profession of no 
mean celebrity, a gentleman whom I much respect, and to whom 
I am greatly indebted for any knowledge I may have acquired of 
the veterinary art. 
Sept, 1886.—An aged favourite brown gelding, the property 
of J. C. Price, Esq., of Mecklenburg Square, was the patient. 
An enlargement on the near side of the face, about the size of a 
hen’s egg, first made its appearance between the orbit and infra 
orbitar foramen. It remained unaltered for some months ; but was 
occasionally accompanied by a fetid purulent discharge from the 
nostril on the same side. 
The treatment adopted at this time was, repeated blisters on the 
tumour, and injections of chloride of lime up the nostril. 
February 1837.—The nostril has become gradually impervious, 
and useless as a respiratory tube. For some time previous he 
made a trumpeting kind of noise in his breathing when exerting 
himself, as his owner continued to drive him. I thought it a 
good case for Mr. James Turner, respecting his new views of 
roaring; but was not able, from certain circumstances which 
occurred at the time, to exhibit the subject to him, although 
I verv much desired to do so. 
March ,—The tumour continued to enlarge with amazing ra- 
pidity. The bones of the face had become partly absorbed, and 
they might have been broken down by the slightest pressure. 
He was cast, and a leaden bougie tried to be introduced through 
the nostril, but ineffectually. A slight sanious discharge fol¬ 
lowed its withdrawal. Ulceration had commenced on its surface, 
and two or three sinuous openings were apparent. 
April ,—The owner determined to turn him out for life. The 
tumour was still enlarging, and was now about the size of a mo¬ 
derate pumpkin. The disfigurement of the face w^as horrible in the 
extreme. The left eye appeared as if pushed up higher than its 
fellow. There were ulcerations in various places on the surface 
of the tumour.
