OBSCURE DISEASE IN A HORSE. 
ambiguous symptoms induced me to request my father to 
examine him, and his opinion was, “ that obstruction of the 
colon existed, probably caused by a calculus, or a tumour 
external to the gut/’ I then administered opening and se- 
dative medicines combined; applied frictions to the abdo- 
men, repeated the enema, and drenched freely with diluents, 
all of which failed to procure any relief whatever. When 
the medicine began to act within the bowels the pain rapidly 
increased, and the other symptoms became much more 
aggravated in their character, indicating that the animal 
could not live long, and all further means resorted to would 
prove useless. He lingered on until 8 p.m., when death put 
an end to his sufferings. 
Post mortem examination . — The cause of death was soon 
made apparent upon opening the abdomen, for the double 
colon was found twisted upon its own axis in the epigastrium, 
the lower surface turned uppermost, closing the passage both 
to and from the sigmoid flexure. The whole portion of it 
was black in colour from the strangulation arresting the cir- 
culation in the bowel. The contents of the intestines, ante- 
rior to the stoppage, were in a pultaceous state ; and the 
feculent matter in the strangulated portion of the gut was 
ordinary in quantity and quality. The other viscera of the 
abdomen were normal. 
A CASE OF OBSCURE DISEASE IN A HORSE. 
By Chas. M. Wood, M.D.Y.S., Boston, Massachusetts. 
February 14th, 1857. — I was called to see a horse in 
Charlestown, belonging to a labouring man, which I recog- 
nised as having been under my care in January, 1856, with 
the prevailing epidemic, influenza, and which in due time 
progressed to convalescence. 
My subject was a gray horse, seven years old, in pretty 
good working condition, and for the past eight months he 
had been used in a light express wagon. Upon examina- 
tion, the following symptoms were presented: pulse 46; 
visible mucous membranes highly injected; coat staring; 
appetite good, but he could not eat ; bowels constipated ; 
urine scanty ; there appeared also some soreness of the 
throat, but he was lively. Upon inquiring how long he had 
been ill, I w as informed that on the morning of December 
24th, 1856, the owner discovered that the animal had not
