it is not a part of physiological ovulation), it must have pre¬ 
ceded the rupture of the cyst, and the formation of the 
tubo-ovarian cyst is due to the assumption of a catarrh of the 
tube and follicle. The tubal catarrh causes circumscribed 
peritonitis and adhesion of the tube. The catarrh of a folli. 
cle causes its dilatation, and its rupture into the tube produces 
the tubo-ovarian cyst. The first stage in the process is ad¬ 
hesion of the fimbrias, which can occur only on the peritoneal 
surface; the fimbrias and their terminatives are therefore 
directed inward. This results in dilatation and dropsy of the 
tube. If a follicle now matures or forms a serous cyst, and 
ruptures into the tube, the tubo-ovarian is formed. Further 
secretion of the tube will enlarge the ovarian part of the cyst. 
This explains the fact that the ends of the fimbrias are found 
upon the inner surface of the cyst. The reason that this cyst 
did not increase in size is due to the fact that the tube was 
always pervious in the direction toward the uterus, and in¬ 
creased pressure within the cyst occasionally gave rise to a 
discharge of fluid into the uterus. 
SOCIETY MEETINGS. 
NEW YORK STATE VETERINARY SOCIETY. 
The fourth semi-annual meeting of the New York State 
Veterinary Medical Society will be held in Buffalo, N. Y., on 
October nth and 12th, 1893. The meeting will convene at 
the assembly room of the Genesee Hotel at nine o’clock a.m. 
October nth. It is expected that there will be present sev¬ 
eral visiting delegates from Europe and from the Eastern 
States, and this will tend to make it an unusually interesting 
meeting to all who attend. A cordial invitation is extended 
to all members of the profession to make a special effort to
