SUCCESSFUL CASE OF LITHOTOMY. 
By the Same. 
On the 19th of October^ a cart-horse, the property of 
T. L. Eweu, Esq., of the Bookery, Dedham, Essex, was sent 
to my infirmary about 6.30 a.m., supposed to be griped. I 
found the patient rolling about in great pain, sweating pro¬ 
fusely ; pulse 70, full and bounding; he was continually 
looking round at his flanks, with frequent straining and 
attempts to stale. 
I explored the rectum and found the bladder exceedingly 
full and very tense, but from its distended condition could 
detect no calculus; I then passed the catheter and discovered 
that something was impacted so firmly in the neck of the 
bladder, that I was unable to move it. 
I determined to operate at once, and for that purpose 
applied the twitch and drew the near hind leg forward with 
a sideline which I secured round the shoulder; I passed the 
catheter up the urethra, a groom steadying it for me and 
holding the tail on one side. I then made an incision some 
three and a half inches long with a very sharp scalpel, cutting 
down through the perineum close on the left side of the 
raphe, on to the catheter, and. with a bistoury enlarging the 
opening into the urethra; and by manipulating with a pair 
of forceps sueceeded in extricating the calculus with very 
little difficulty, thus allowing the urine to escape freely 
through the opening. 
After washing the bladder out with tepid water I brought 
the lips of the wound in apposition with sutures and 
thoroughly closed it by several applications of collodion until 
a thick layer was formed. I then poured some collodion on a 
piece of wadding, about five inches long and two wide, and laid 
it on the wound over the coating of collodion; this adhered 
so firmly for fourteen days, that no fluid could escape through 
the wound, at the expiration of which time it became de¬ 
tached. I removed the sutures and found, to my gratification, 
that the wound was completely cicatrized. 
On the 26th of October I sent him home and he has been 
at work ever since. No medicine was administered as the 
removal of the calculus afforded entire relief^^ till the third 
day, when, as his urine was rather thick, I gave hydrochloric 
acid in his water for several days in succession.
