TUMOURS ON THE MEMBRANA NICTITANS ; UNDER 
THE JAW, AND AROUND THE RIGHT PAROTID 
GLAND. FUNGUS HEMATODES. 
Bj/ M. C REPIN, Paris. , 
A MARE, about 18 years old, had had for many years an 
ulcerated tumour on the merabrana nictitans of the right eye, but 
which did not prevent her from doing her work. Almost imper¬ 
ceptibly, during so long a period of time, it had augmented by 
little and little, until it had become as large as a pigeon’s egg, 
and the eye was nearly covered by it. There ran from its most 
salient point a great quantity of sanious pus, which, mingled with 
the tears, continually flowed down the cheek. This tumour did 
not seem to cause any considerable degree of pain. I could not, 
for a very long period, obtain the consent of the owner to operate 
upon her ; but at length I did prevail upon him, and the operation 
was performed on the 11th of February 1831. 
It w^as exceedingly simple. The mare being cast on her left 
side, I passed a thread through the tumour, drew it out of the eye, 
and cut it off with a curved pair of scissors ; and there re¬ 
mained absolutely nothing of the cartilage which had formed the 
base or nucleus of it. The consequences of this extirpation were 
as fortunate as could be wished : the mare returned to her work 
on the fourth day, and the eye was not much inflamed: one 
inconvenience only remained for a few days; this was relaxation 
of the lower lid, which, distended beyond measure by the 
tumour, did not immediately regain its former tension. A 
little cold water however served to remove this, and no dressing 
or cover was at any time applied to the eye. 
From the time of the first ^development of the tumour, there 
had appeared a glandular substance under the jaw, which had 
slowly increased, and which, at the period of operating, was not 
so large as a'nut, but was exceedingly, hard. I merely hint at it 
now—I shall have occasion to refer to it again by and by.
