CANCER IN HORSES.

and a large, bulging, convex prominence occupied about four 
inches of the frontal ends of the nasal bones, and disappeared 
on reaching the plane of the supra-orbital processes. 
From the 24th to the 30th, he never lay down, took scarcely 
any food, was quite lethargic, stood with the legs projecting 
in four different directions to give his reeling body the best 
mechanical support, and the drooping pendulous head was 
generally turned to one side. On this latter-mentioned day 
(the 30th), it was considered best to destroy him. Whilst 
being brought out of the stable he fell down, and, strange to 
say, rose again instantaneously ; this he did for three times 
successively. On recovering his feet for the last time, he 
would not advance another step, and had to be killed on the 
spot. 
I did not see this horse during life. After attending a few 
times as a dispensary patient, he became unable to walk, and 
was kept at home under the professional care of Mr. Sheriff 
(then a student, now a graduate of this college). The fore- 
going account is abridged from notes which Mr. Sheriff 
recorded, and kindly supplied at my request. The head was 
brought to town and dissected by me the same day (30th). 
External appearances . — The left eye and its outward appen- 
dages were much protruded, as well as concealed and struc- 
turally involved in a fungoid growth, most prominent on the 
cornea, membrana nictitans, and conjunctiva. This growth 
was of a dirty flesh-colour, partially covered with bloody pus, 
friable in texture, and vascular ; it reminded one of appear- 
ances seen in the profuse granulations of a cankered foot, after 
their vascular surface is exposed by scraping away a few 
hours’ growth of abortive horny covering. The right cornea 
w r as opaque, but structurally entire, and no visible organic 
disease was observed in this eye The swelling on the face was 
elastic, a condition evidently due to softening of bone and 
swelling beneath. The temporal swelling w T as mainly 
cedematous. 
Dissection . — After removing the facial integuments, it was 
found that the elevated nasal bones, and contiguous borders 
of the frontal, lachrymal, and superior maxillary bones, would 
readily cut with a strong knife. Their subcutaneous surfaces 
were accordingly sliced away ; a tumour w 7 as found lying 
immediately within, and occupied almost the entire cavity of 
the cranial and facial sinuses. It was slightly attached to 
the osseous roof and sides of these cavities, and had induced 
caries or interstitial absorption of every bony surface with 
which it came in contact. The upper third of the septum- 
nasi, the hard bony plate dividing the cranial from the facial
