SCROFULOUS DISEASE OF THE EYE-BALL, ETC. 108 
from the orbit ; its cornea was a little larger and more convex 
externally, but not distended (as it became a short time prior 
to the mare^s death), and it was for the most part transparent, 
but a view into the posterior chambers was almost completely 
intercepted by large deposits of yellow material. In the area 
of the enlarged pupillary opening blood-vessels of consider- 
able size could be seen distributed amongst the masses of 
lymph. No pain was evinced upon ordinary pressure to 
the globe, nor was there any weeping or abnormal injec- 
tion of the conjunctiva present. 
I learned, from a person who had known the mare all her 
life, that when between two and three years old she received 
a severe injury to the eye, but that it had been in the same 
condition it then was for upwards of two years. The mare 
was at once put to, and continued at, daily work until Nov. 
3rd, when the horsekeeper requested me to examine the eye, 
which he said “he thought had enlarged during the last two 
or three days.” I found the globe protruding more than a 
quarter of an inch beyond its natural boundary ; its tunics 
w r ere full and even distended ; the conjunctiva was only 
slightly reddened, little weeping ; the blood-vessels, which 
were previously visible through the cornea, had increased in 
number and size ; no pain was evinced on gentle manipulation. 
The mare was in excellent robust condition, but dull, and the 
appetite was not good. The excretions were natural ; pulse 
was forty, and soft; the breathing was normal. During the 
progress of the case I saw the mare daily. On the 6th the 
condition of the eye was much the same, but on each side of 
the trachea, opposite the lower third of the scapulae, a large 
indurated tumour, unconnected with the skin, painful on 
pressure, had appeared, together with some oedematous 
swellings on the breast, and along the sternum ; the pulse had 
increased in frequency to fifty, the appetite was fastidious, 
and the urine scanty and high coloured. By the 12th the 
swellings had increased in size, and appeared to encircle the 
lower part of the windpipe, and also to extend in smaller 
quantity along both sides of its course, nearly up to the 
larynx. The amount of accompanying oedema (never very 
extensive) varied, perhaps in equivalent ratio to the action of 
the kidneys, and from the effect of gentle exercise. The eye 
remained “ in statu quo.” As the tumours did not by this 
time show T the least inclination to take on suppurative action, 
although every means had been employed to induce it, I 
began to fear their nature must be cancerous. The constitu- 
tional symptoms had all improved; the pulse was forty, full 
and strong ; the appetite and spirits were good ; and the mare
