mine the thing more exactly, I dissected the penis and the rectnm, and having 

 taken them out of the body, and laid them on a table, laying open the urethra, 

 to examine whether there was any carnosity, as the surgeon who first intro- 

 duced the catheter had suspected ; but there was none, and that ductus was as 

 plain and sound as could be, except the dilaceration the catheter had made in 

 it. Tiien introducing a conductor into the bladder, I divided it quite; and first 

 it was observed, that the round bag, which consisted of two bladders, or rather 

 two cysts, were divided from each other only by a membrane ; that which was 

 next the true bladder was something larger than it, the other which lay on the 

 right side being much smaller. Each of these two cysts had its orifice opening 

 in the neck of the natural bladder, which was longer than it naturally is. 

 Neither of the ureters were inserted into any of these cysts, into the neck, of 

 the true bladder, by the orifices of the two cysts, insomuch that the urine 

 could be equally received by them and the bladder. 



Secondly, it was observed that the glandules of the true bladder were exceed- 

 ingly large and red, that colour being very likely the effect of the inflammation 

 caused by the dilaceration of the urethra. I have oftentimes observed that a 

 thick mucus, which runs out of the bladder, and which some take to be the 

 matter of an imposthume or ulcer in the kidneys, is only produced by those 

 glandules of the bladder becoming scrophulous ; and that when that mucus 

 grows thick and clammy, it causes the same pain on the neck of the bladder, 

 as if it were a stone. The glandules of the great cysts were very apparent, but 

 very small, but they were not at all sensible in the smaller cysts. 



Now it is easy by the description of these bladders to account for the symp- 

 toms; for by the situation of the great cysts, it is plain that the urine could 

 not be discharged but by the force of the inspiration, its own muscles being 

 not able to force it out, and consequently could only be voided by little and 

 little; and these efforts of inspiration were to be the greater, when there was 

 but a small quantity of urine, because it required a greater force to make it 

 ascend from the bottom of the cysts, which could not be done but with great 

 labour and fatigue.
