boundary, which extended as far as the second molar. Other 
peculiarities were also detected by opening the mouth with a 
speculum and throwing reflected light into it. The last left 
molar, partly covered by neoplastic granulations, on both sides, 
were loose. The projection formed by the tumor was principally 
well marked on the level of the molars. Upon the greatest part 
of the palatine arch, it was scarcely visible, and the mucous 
membrane seemed simply covered with a kind of granular mem¬ 
brane. Uight thrown into the nasal cavity showed its floor de¬ 
formed, bulging, with the mucous membrane pushed aside by 
the tumor. This had started on the mucous membrane of the 
month, or at the interior of the maxillary ; and in this last sup¬ 
position had made its principal development in the mouth. 
Another important symptom was also noticed, which consisted 
in a double adenopathy, which left no doubt as to the nature of 
the disease. The maxillary ganglions on the right side formed 
a bosselated, very hard mass, as big as a nut, adherent to the deep 
tissues, but not to the skin. Those of the left side had the size 
of a pigeon’s egg, also irregular and very hard. The diagnosis 
of epithelioma of the maxillary could not be doubted. The ani¬ 
mal was incurable. The owner sold him and we lost sigdit of 
him. 
Here is another similar case, observed in January, 1891. A 
twelve-year-old gelding, was presented at the clinic with the 
following history : Three months ago, it was observed that his 
face was slightly swollen, mastication had become difficult, and 
he had an offensive odor discharging from the right side. On 
the right lateral side of the face the swelling was diffused, quite 
hard to pressure, a little painful, extending from the anterior 
extremity of the maxillary spine upwards, down to on a level 
with the first molar. The maxillary glands of the same side 
were affected. They formed a very hard tumor, bosselated, 
elongated in the direction of the axis of the head, movable under 
the skin and but little adherent to the tissues under. From the 
right side flowed a greyish, foetid discharge. In the nasal cavity, 
by spreading the nostrils open, a greyish tumor was seen, filling
