pain, and every other fymptom which chara^lerifc 
the cancer. Thefe kinds of wens, warts, and ti> 
bercles, which are fituated in the great angle of the 
eye, upon the lids, or the nofe, very often flioot out 
their roots upon the cartilages, that is, upon the 
very membranes which cover them, and the roots 
fmk in fometimes to the fubftance of the cartilage 
itfelf, which they fwell and tear in the end. 
The more cancers are touched with cauftics, the 
more they are irritated j therefore there is but one 
method, but it is a fure one, of curing them, and 
hindering their progrefs j which is, to take them off 
with a cutting inflrument, deftroying the Periofteum 
and Perichondrium, or even the lids, if the cancer 
has penetrated them in their fubftance, with their 
cartilages : which the following obfervations will 
prove. 
Obfervation I. upon a cancerous upper- lid. 
Auguft the iith, 1736, I was called to Madam 
de la Fague, an Urfeline Nun, at Bourdeax, forty- 
five years old ; to fee a tumor upon the upper-lid 
of the right eye, which ftie had for twenty years : 
it begun by a fmall wen, and inereafed by degrees, 
fo as very much to incommode the patient. 
She applied to a furgeon, who began by applying 
fome drops of a liquid cauftic, which enraged the 
tumor ftiil more; which he appeafed again by ano- 
dyne medicines ; and then the tumor remain’d along 
time without any f'enfible increafe; although the 
patient felt a continual lharp pain in it.. But, aS' 
even the lea ft diforders are impatiently borne, flie 
was willing to be relieved, and confulted another 
furgeon, who took off the tumor with a cutting.
