some blood ; he felt a pain and weight in the hinder part of his head and neck, 

 and lost his appetite, but concealing his case, nothing was done for more than 

 a fortnight. After the fall he went into the country, where he staid a few days, 

 and as he was coming back he had a frequent desire to make water, and alighted 

 from tlie horse several times, but could make no urine ; he vomited in this 

 time ; the suppression had continued more than 24 hours when I came to visit 

 him. He had a great pain in his head, a pain in his back and groins, and in 

 the region of the bladder, which was swelled, and he could not suffer it to be 

 touched. I caused some mild diuretics to be given to him presently, anointed his 

 groins and the regio pubis with the usual ointment, and caused a clyster to be 

 injected ; upon which, that night he passed first some sand, and then some urine 

 by spoonfuls. I caused hisn afterwards to be put in a half bath of appropriate 

 simples. He was on the following days let blood and purged ; and the pain in 

 his head being very troublesome, a large vesicatory was applied to the nucha, 

 which discharged much humour from it. While this was doing much sand was 

 passed of a greyish and whitish colour, and after the first purge, he began to pass 

 stones by the yard, of a considerable size, with pain in the back some time 

 before they fell down, then in the groins or along the ureters, and most in the 

 right side, yet sometimes in the left. He found the yard much dilated while 

 they passed it, and he had a smarting pain then and while the urine flowed, 

 the stones came in with the first of the urine ; he took several emulsions which 

 had a good effect. Some of the stones were round, some oval, some angular. 

 Some of a pyramidal form, some cubical. The colours were different, some 

 whitish, some brown, some bluish, some black, or of a dark colour, the con- 

 sistence of a sandy stone, and some looked like bricks, some in thickness the 

 10th part of an inch, some the 12th part of it, some i- an inch long; most of 

 them approached to a triangular form. He found a weight in the bladder when 

 they fell down, and he told me, he was sensible they came down the ureters. 

 He leaped and ran sometimes to hasten their descent. I was present when he 

 passed one, and I heard it fall into the urinal, and saw it there ; his relations 

 saw most of them when they were passed. These stones are not made up of se- 

 veral coats over each other, but look like bricks, and may easily be reduced to 

 powder. In a fortnight's time he has passed above 6o of them by the yard. 



Since writing this, the boy has passed several triangular stones, some thicker 

 than the 6th part of an inch, and upon the 20th and 21st instant he has passed 

 3 by the fundament, 2 of them triangular, pretty hirge, and 1 as large as a little 

 plum, but of the shape of a pear, of the same sandy consistence as the former, 

 and of a greyish colour. He has passed none by the yard since he passetl these 

 the other way.
