increafe, as that I could not forefee any great haz- 
ard that was likely to attend its extirpation. 
From the uncertainty in which I was concerning 
the true nature of the cafe, I determined to adl very 
cautioufly. I made an incilion thro’ the fkin and cel- 
lular membrane, from the upper part of the fcrotum 
quite down to the lower; by which I difcovered a 
firm, ftrong, white membraneous cift, or bag, con- 
nected loofely with the fkin by means of the dartos ; 
I differed all the anterior part of this cift, quite 
clean ; and found, that, as I traced it upward, it be- 
came narrower, and feemed to proceed from the groin : 
This determined me to try if I could not free the 
pofterior part of it alfo. In doing this I difcovered • 
the tefticle, . which was much comprefled, flat, 
very fmall, and lay immediately behind the tu- 
mor. 
The diftedlion of the tefticle and of the fpermatic 
chord from the bag, and from its neck (which I 
was obliged to do in order to preferve the teftis) 
took up fome time, and gave me fome trouble ; but, 
when I had finifhed it, 1 found that the cift was de- 
pendent from, or continuous with, a membranous 
tube, or dudl, of about the breadth of a large wheat 
ftraw, which feemed to pafs out from the abdomen, 
thro’ the opening in the oblique mufcle, along with 
the fpermatic veftels. 
When I had perfectly freed this du£t from all con- 
nexion, I cut it thro’ immediately above the tumor; 
upon the divifion of it a quantity of limpid fluid i 
(not lefs than two ounces) followed, and the mouth 
of the cift expanding itfelf difcovered a large ftone, 
exadtly refembling the calculi found in the urinary 
bladder;
