infinuated itfelf through the wound of the cornea, 
forming a ftaphyloma ; but M. Daviel fpeaks of it as 
an occurrence he has met with, and fays it may be 
cafily replaced by the fmall fpatula. 
I prefume a greater number of operations will 
prove this account very deficient : But I have here 
communicated all that I have done, and all that I 
know on the fubject ; not having fupprefs’d one ex- 
periment, nor, to the belt of my remembrance, one 
circumftance, either to the honour or difgrace of the 
operation. 
It is to be hoped, that, when it fhall be more ge- 
nerally practifed, ingenious men will render it ftill 
more perfect : And I fhould not be furprifed, if the 
ufe of a fpeculum oculi fhould hereafter be efteemed 
an improvement : But then it muft be contrived fo, 
as that it fhall not comprefs the globe of the eye ; 
or, if it does, the operator muft be careful to re- 
move it in the inftant the incifion is making, left, 
by continuing the preffure after the wound is made, 
all the humours fhould fuddenly gufli out. 
It was impofiible for me to make any remarks on 
this operation, without criticifing on M. Daviel, as 
M. Daviel has not only the honour of having firft 
practifed it, but is the only writer who has treated 
the fubject, at leaft that I am acquainted with. I 
therefore flatter myfelf, that this attempt to im- 
prove upon what he has laid down, will not be con- 
ftrued as a reflection on him, or his practice . For, 
however his invention may be perfected by others, is 
my opinion, it is ftill to him principally, tno, the 
world will be indebted for the benefit of the difco- 
very.
