High Operation for the Stone. 49 



No one bad symptom occurred afterwards : the urine continued for 

 about five weeks to come occasionally by the wound in small quan- 

 tities, the rest by the natural passage : the wound itself continued 

 to look healthy from the first, and gradually closed until the 31st 

 July, when it was completely healed, and the patient voided his 

 urine in a full stream through the urethra. 



Thus terminated this successful case; and, I am strongly in- 

 clined to believe, that the patient's recovery would have been still 

 more speedy, had the catheter been sooner altogether withdrawn 

 from the bladder; for it was retained almost constantly in that 

 situation about three weeks, removing it night and morning only, 

 for the purpose of clearing it of mucus. 



The stone weighed eleven drachms two scruples and four grains. 

 It is two inches long and one inch and half in width. A section 

 has been made of it, and my friend Dr. Prout has had the kindness 

 to analyze it for me. The result will be found in the Doctor's note 

 addressed to me. 



I have the honour to be, 

 Dear Sir, 



Your very obedient humble servant,

 My dear Sir, 



The nucleus of the calculus whicli you were kind enough to 

 leave for me, consists essentially of the lithate of ammonia, mixed 

 with some oxalate of lime, (and probably a little carbonate of 

 lime,) the phosphates, and animal matter. The exterior laminae 

 are chiefly composed of the phosphates ; but two or three small 

 fragments detached from the surface were found to consist chiefly 

 of the phosphate of lime ; and this circumstance made me anxious
