CALCULI IN THE BLADDER. 193 



Upon introducing the hand into the gut the stone was distinctly 

 felt ; and, after a few days' preparation, by bleeding and openins: 

 medicine, with a spare diet, the horse was placed on his back, 

 and an opening made in the urethra, near the anus, in the 

 manner I shall soon describe. Through this opening the fore- 

 finger was introduced into the bladder, while an assistant had 

 his hand in the gut to press up the stone that it might be felt 

 by the operator, who then introduced an instrument, guided by 

 his finger, with which two incisions were made in the neck of 

 the bladder, one on each side. The forceps were now intro- 

 duced and the stone laid hold of, but it broke into small pieces, 

 Avhich were all extracted, and found to weigh five ounces. No 

 dressing was applied to the wound, but some linseed infusion 

 was injected into the bladder. The horse got up without as- 

 sistance, was bled three times the same day, and not allowed any 

 solid food. His drink was white water (bran tea) ; the bowels 

 were kept open by clysters. On the fourth day he was allowed 

 a small bran mash and some straw. This allowance was gra- 

 dually increased. There was scarcely any fever; the wound 

 suppurated, and looked healthy. During some days part of 

 the urine passed through the wound, and about the 22d day 

 it was perfectly healed." 



A short time since I received a letter from Mr. W. Mog- 

 ford, some years ago my pupil and assistant, to inform me 

 that he had extracted a stone from a horse's bladder, which 

 weighed more than five ounces. He says, also, that he is 

 convinced that a stone of eight ounces might be extracted 

 by the means he adopted on this occasion ; that is, without 

 wounding the neck of the bladder, as La Fosse did, and 

 without the aid of forceps. AVhen the horse was brought to 

 ]Mr. M. he observed a peculiar stiffness in the hind parts, a 

 frequent desire to stale, and a dribbling of urine from the penis 

 for some time afterward. By bleeding, embrocating the loins, 

 emollient clysters, and rest, these symptoms disappeared, and 

 the horse was sent to grass. He soon broke out of the field, 

 and, crossing the country, returned to a pasture in which he had 

 some time before been kept. This exertion cansed a return of 

 the above symptoms, and he was again brought to ISlv. jNL, who 

 now passed his hand up the fundament, in order to feel, througli 

 the rectum or gut, M'hat urine there was in the bladder, when 

 he distinctly felt a stone in it. He communicated the circum- 

 stance to a suro;eon, who could not believe it until he had ex- 

 amined the horse himself, when he also felt a stone in the bladder 

 very distinctly. Mr. j\I. now proceeded to the operation, and 

 having cut down upon the whalebone rod which had been 

 passed up through the penis, he continued the incision, by means 

 of a conductor and a probe-pointed bistoury, to the neck of the
