ter condition had caused a secondary hydronephritis. 
By reference to the literature on this subject, we find that 
in man, fibroma of a papillary nature to be the most often 
met, which also causes a periodic hemorrhage. 
Primary carcinoma of the bladder is seldom seen; in the 
male it is secondary to the same condition of the prostate ; in 
the female to the uterus and vagina cancers. In zoology 
tumors of the bladder are infrequently met, a fact earlier em¬ 
phasized by Pflug and Roll.— Monatshr. f. Thierheilk. 
EPITHELIOMA IN THE MAXILLARY SINUS. 
Diseases of the maxillary sinus, and in fact of the sinuses 
in general, are of sufficient rarity to excite more than a pass¬ 
ing interest to the profession. This is due in part to the great 
similarity existing between the semiology of the affections 
and glanders ; the abundant nasal discharge of a thick char¬ 
acter, the hypertrophy of the submaxillary lymphatics and 
occasionally the swelling of the facial bones all tend to con¬

For the observation of the case below described, we are 
indebted to our colleague, Mr. Haune, of Barum, who drove 
us on the 17th of March to examine a supposed glandered 
horse. 
The animal, a brown gelding, nine years of age, exhibited, 
on the right side a bulging of the superior maxillary bone. 
The center of the same was pierced by a foramen which led 
to the maxillary sinus or antrum of highmove; by introduc¬ 
tion of the digit no definite conclusion concerning the origin 
and disposition of the pathological process could be arrived 
at. It seemed as though the space were only partially filled 
with a soft tissue mass; a muco-purulent fluid escaped the 
right nostril, which contained flakes of a whitish color ; a sim¬ 
ilar dejectus had been seen for a few days from the left nostril. 
In the oval cavity the third superior molar on the right 
side was missing, and the first and second molars were but 
loosely implanted. From between the cheek and teeth a
