On the 19 th of October the horse entered the infirmary 
for a slight running from the right nostril; the gland on the 
same side was also tumefied. This discharge soon became 
more abundant and fetid, and at intermissions bloody. By 
percussing the bones over the sinus, the dulness of the sound 
diagnosed disease on the right side. The horse was now 
isolated, and treated accordingly. In the month of November 
a tumour was observed on the zygomatic process of the tem¬ 
poral bone. A blister was applied to this tumour; but it soon 
became indolent, and of the size of a hen’s egg, in the centre 
of which there was a soft point. Several times the tumour 
was punctured, but without any good effect. In the mean 
time the discharge from the nose had greatly increased. On 
the right side it was of a white colour, thick, purulent, 
adhering to the sides of the nostril, and having such a 
fetid smell that it infected the stable. The respiration 
was performed by the left nostril only. The horse soon 
lost his appetite, and was quickly very much out of con¬ 
dition. From the existence of these symptoms there remained 
no doubt that the right nasal cavity was the seat of caries of 
the bone, and that it was also obstructed by a polypus; 
besides which, the tumour on the zygomatic process had ex¬ 
tended to the external table of the superior maxillary bone. 
There was only one resource, which was trephining, so as to be 
able to ascertain the extent of the disease. The horse having, 
however, many of the symptoms seen in glanders, was con¬ 
demned to be shot. 
Post-mortem examination .—The skin having been carefully 
removed, one was struck with the amount of effusion which 
had taken place into the areolar tissue just below the zygo¬ 
matic arch, which extended to the commissure of the lips. 
In the place of the zygoma there was found a whitish tumour, 
which grated under the scalpel, having a sarcomatous 
appearance. In the centre of it was a softened spot, and by 
pressing the finger on this it was easy to show its con¬ 
nexion with the frontal sinus. From it was discharged about a 
quart of white ichorous pus, having a fetid odour. On en¬ 
larging the opening, it was found that the bony substance of 
the upper maxillary, corresponding to the three last molar 
teeth, as well as the zygomatic process, was completely trans¬ 
formed into a semi-sarcomatous substance, assuming the 
shape of the bones thus altered, and presenting a thickness 
of from three to four centimetres. In order better to ascer¬ 
tain the position and extent of the lesion, the head was 
opened crossways, on a level with the orbital arch. On 
removing with care the maxillary bone, the last three molar
