under the bladder, which reached as 

 high as the navel, and pulhing it up- 

 wards, The tumor is felt of a di£Ferent 

 bignefs at different times, according to 

 the greater or lefs quantity of urine con- 

 tained in the bladder ; which will be ac- 

 cording to the quantity of drinks taken, 

 or a freer difcharge of the urine at one 

 time than another. And, when the tu- 

 mor is not too tender to bear the experi-* 

 inent,' the urine may be fqueezed out by 

 comprefling the bladder. If to thefe 

 we add pain and difficulty in pafling the 

 urine, a retention of it, or an incapacity 

 to retain it, no doubts with regard to the 

 diftemper can remain. 



Whether the veftcae durae of Hip** 

 pocrates may be reckoned the fame, or to 

 have an affinity to the prefent difeafe, ic

 would appear, however, to be a diilcm-^ 

 per of pure inflammation ; while ours is 

 altogether a membranous tumor, with- 

 out inflammation, except what is acci- 

 dental ; though thefe may mutually be 

 thccaufe of eaqh other, A membranous tu- 

 mor.
