256 FUNGUS H.EMATODES TN THE EYE OF A MARE. 
different means; and her health had continued pretty good until 
within the last few weeks, when the bleeding had become more 
considerable, and she exhibited, by coma and other symptoms, 
indications of the brain having become affected. Judging from 
the appearance of the tumour, with its disposition to bleed so 
profusely, and the fact of its having been formed in the interior 
of the eye, 1 concluded it was not of an ordinary description ; 
and, suspecting it to be a case of fungus haematodes, I re¬ 
quested Mr. Alport, surgeon, residing in Lichfield, to see it 
with me, who pronounced it to bear all the specific characters 
of that disease in the human subject. 
I had previously determined upon extirpating it with the 
whole of the contents of the orbit, and which was now effected. 
I found it necessary, in consequence of the superiority in size 
of the tumour to that of the orbit, to dissect a portion of it away, 
level with the orbital margin, before I could make it practicable 
to remove that which was contained within the orbit. With 
some difficulty, owing to an immense hemorrhage, the whole was 
extirpated, weighing about two pounds. The sclerotica within 
the orbit was filled with firm medullary matter of a yellowish 
colour; the optic nerve had its usual appearance; but there was 
no trace of any of the other component parts of the eye. The 
portion that was first dissected away had a somewdiat similar 
though darker appearance towards its centre ; and became very 
vascular towards its exterior. The orbit was filled with tow 
after the operation, and a bandage applied to retain it. The 
mare had physic, and was sent home. 
I saw her two days afterwards, when she was swollen pretty 
much about the parotid gland and top of the head. These 
parts were fomented, and physic was given, which operated 
well. I did not see her again, but understood from the farrier 
who attended her, that the swelling increased until about the 
seventh day after the operation, when the comatose symptoms 
became more apparent, and she died in three weeks from that 
time. The tumour was larger than it had ever been, which ap¬ 
peared more extraordinary, as I considered that I had removed 
the whole of the tunic from which it had originated. He opened 
the head, and found the brain very soft, and containing much 
serous fluid.
