the stone was extracted, was reduced to -i- an inch in length from the fraenum 

 backwards. But although he introduced a leaden pipe near 3 inches long into 

 the urethra, the urine never came through the natural orifice, but still continued 

 to pass through the aperture. 



The passage in the back of the penis, made by the urine before the operation, 

 healed up kindly. He afterwards much rejoiced that the incision could not be 

 healed, because he had voided several large stones that way; which he most pro- 

 bably must have been cut for again, had that been closed. Foi" several years his 

 urine did not drop, but by the introduction of a knitting needle, or such-like in- 

 strument, which would move the stone : and this operation generally took up 2 

 hours every morning. 



It might easily be seen which way the stone lay in the penis, by observing some 

 holes in it, which the patient had made with the knitting needle, hoping to push 

 through it in time. These holes were in the fore-part, or against the natural 

 orifice. The other end was found quite polished, by the friction of the small 

 stones againt it. The superior part was like the glans penis : the stone being 

 placed on a table, and observed at a small distance, it seemed not unlike a glans 

 cut off, only larger. 



A fortnight after the operation, his wife was delivered of a 3d child. She has 

 the character of a very virtuous woman; but how the semen in coitu could pass by 

 this stone, when the urine could not, but with such difficulty, Mr. H. did not 

 pretend to determine.

The best whispering place I ever saw was that at Gloucester : but in Italy, in 

 the way to Naples, 1 days from Rome, I saw, in an inn, a room with a square 

 vault, where a whisper could be easily heard at the opposite corner, but not at all 

 in the side comer that was near to you. 



I saw another, in the way from Paris to Lyons, in the porch of a common inn, 

 which had a round vault ; but neither of these were comparable to that of Glou- 

 cester; only the difference between these last 2 was, that to this, holding your 

 mouth to the side of the wall, several could hear you on the other side; the voice 

 being more diffused. But to the former, it being a square room, and you whis- 

 pering in the corner, it was only audible in the opposite corner ; and not to any 

 distance from thence as to distinction of the words. And this property was com- 

 mon to each comer of the room, and not confined to one. 



As to echos, there is one at Bruxelles that answers 15 times: but when at
