equal bulk with the difeafed eye before extirpation. 
All topical applications, to contract this fungus, 
were ineffectual, and the application of cauftics or 
efcharotics was prudently avoided, left they fhould 
produce a carcinomatous ulcer. The difeharge was 
chiefly a purulent ferum : on which account, ever 
fince the beginning of November he was kept upon 
a dry diet. 
In February 1757. t ^ ie remaining coats of the eye 
began to appear at the mold prominent parts of the 
excrefcence, and feetned white like a part of the 
conjunttiva. On touching it with the finger, a di- 
ftinCt fluctuation was felt, and an hydrophthalmia 
perfectly difeovered ; but neither the thicknefs of the 
coats, nor the fenfibility of the parts, would permit 
a punCture to be made, till the cyft, which appeared 
formed by the diftenfion of one of the coats of the 
eve, was freer from the fungus. 
The cyft continued daily to extend itfelf, and to 
feparate the fungous edges ; the fluctuation became 
more manifeft, and the membranes thinner. At 
length, on the 15th of June 1757, Mr. Hopkins 
opened the cyft with the point of a lancet, and let 
out a large cup-full of limpid ferum, without fmell 
or tafte. The boy felt very little pain in this opera- 
tion. The cavity was filled with dry lint, and com- 
prefles dipt in warm red wine and water were applied 
over it. All the night following, and feveral days 
after, a great difeharge of ferum came away. On 
the 19th the fungus was confiderably leffened. Mr* 
Hopkins then drefled the wound with warm un~ 
guentum e gummi elerni , and wafhed the fungus 
with a lotion of aquarian calcis , rojarum , et tinc-
