INTESTINAL CALCULUS.

faeces had been passed. Ordered gruel, linseed tea, and 
enemata as before, and the abdomen to be blistered. The 
absence of pain I feared was referable to sphacelus having 
set in. 
6 p.m. The pain has returned again with all its severity ; 
the pulse is ranging at 86; the mucous membranes are 
changed to a leaden hue; the breathing is hurried, and 
frequent sighing is also present; the mouth is hot and dry, 
with a fetid smell from it ; the extremities are cold, the eyes 
fixed, and the animal walks round the box, apparently in 
much agony, turning his head towards his side. The bladder 
had been relieved several times during the day. The blister 
had taken no effect. My prognosis could now be no other 
but unfavorable. I, however, gave 
Hydr. Chlor., 5 SS \ 
Antim. Tart., 5j ; 
Sp. Ether. Nit., §ij ; 
Tinct. Aconiti, 40 drops ; 
Sodae Carb., %jss. In draught. 
Ordered the enemata to be repeated, and the animal to have 
chilled' water frequently, and be well attended to during the 
night. My diagnosis w T as that a calculus existed in the intes- 
tines ; which would account for the obstinate constipation and 
inflammation of the bowels. At 10 o’clock on the following 
morning death put an end to my patient’s sufferings. 
Being Sunday, I was prevented making a post-mortem 
examination, but was obliged to have the animal removed by 
the “ knacker,” whom I particularly requested to closely 
examine the intestines. The following day he sent me the 
calculus, weighing, 'when wet, 4 lb. 3 oz. He informed me 
that it was taken from the colon, and was imbedded in a 
large mass of faeces. 
I am informed that the horse had performed his usual 
duties in good spirits on the day he was taken ill ; that his food 
consisted of hay, chaff, ground beans, and oats, and that he 
had been at the station for about three years, and never was 
known to suffer any abdominal pain. Previous to his re- 
moval to Sudbury, he had been working on the Ipswich line 
of rails. 
Examination of the Calculus . — The concretion was one of 
the kind we have ventured to designate " mixed calculi ;” 
these being composed principally of the ammonio-magnesian 
phosphate mixed with the hairs of the oat. 
Being much drier than when sent by Mr. Hutton, its
