fever, great wasting away of the whole body, and almost a continual and invo- 

 luntary discharge of small quantities of urine. 



The man was conveyed to London in a waggon. The parts were then arrived 

 to so great a degree of distention, inflammation, and tenderness, that on the 

 journey they burst, and there was discharged through an opening made in the 

 perinaeum (that is, the space between the anus and scrotum) one of these stones ; 

 the other stone remained firmly fixed in the urethra, which Mr. W. easily re» 

 moved, having first cut away as much of the diseased integuments of the accele- 

 ratores urinae muscles, and distended urethra, as he judged necessary to be re- 

 moved for this purpose. After the removal of these parts, he brought together 

 the lips of the wound, and kept them so, by means of what surgeons call the 

 twisted suture, till the parts were united, which was effected in about a fortnight. 

 Before the suture was applied, he introduced a ductile instrument, of a conveni- 

 ent size, through the penis into the bladder, by which means the passage was 

 kept equally distended. 



This operation so effectually answered his expectation, as totally to remove 

 the incontinence of urine, as well as every other symptom that had attended the 

 complaint ; and the patient was in a short time restored to his usual healthy state 

 and corpulency. 



N. B. In the 2 instances here related, as well as in the case of Thomas Bing- 

 ham, whose history Mr. W. communicated to the n.s. on the 13th of Dec. 1759, 

 (vide Phil. Trans, for 1760) he observes that these patients according to the best 

 information he could get, were never attacked with a suppression of urine, or a 

 regular fit of the stone ; for which reasons, he concludes, that the formation of 

 these calculi originally commenced in the urethra itself, and that the stream of urine 

 in its course from the bladder through the penis, had gradually formed those 

 groves or channels, so apparent on the surfaces of these compact and hard bodies, 

 over which they occasionally were voided ; by this means a passage for the urine 

 always remained open and unobstructed. 



Plate 14, fig. 3, represents the size, shape, and appearance of the stone, with 

 the grooves on its superior surface, that was voided through a laceration of the 

 perinaeum, described in the case of Henry Taught, of Hastings in Sussex. Fig. 4 

 represents the 1 stones that were lodged in the perinaeum of Robert Bolley, a 

 young man of 11 years of age, as above mentioned, with the polished surfaces. 

 A, B, where they came in contact with each other. Fig. 5 are these 1 stones 

 joined together, with their several eminences and depressions, as they lay in con- 

 tact with each other in the perinaeum.
