about the time vesication was seen in others, and, in despite of all 
the means employed, the animals died. This, nevertheless, is the 
characteristic of the exanthemata ; and, should the critical eruption 
by which they are distinguished be in any way suppressed or in- 
terfered with, some internal organ generally becomes, as it were, 
a substitute for that originally intended by Nature to answer her 
purpose, and death results from actions being interfered with of 
more importance to life than those usually deranged when the dis- 
ease pursues its usual course. 
INTUSSUSCEPTION IN A COLT A DAY OLD. 
By Mr. W. A. Cartwright, M.R.C.V.S., Whitchurch, Salop. 
On Monday evening, about seven o’clock, May 5th, 1845, a 
cart-mare of Mr. W. Hassall’s, of Allport Farm, foaled in the 
field, and soon afterwards both were brought home. The foal 
sucked a little. The next morning, about ten o’clock, it was seen, 
and was thought to be unwell, and soon afterwards it became 
worse, and shewed symptoms of belly-ach. 
12 M. — I first saw it. Symptoms. — Lifts its hind legs up and 
down, and is very uneasy and restless ; lies down now and then, 
and rolls over occasionally; abdomen not at all tympanitic, nor 
can any hardened portions of meconium be felt therein ; but on 
introducing my finger up the anus, I drew several lumps out, the 
retention of some of which I fancied might be the cause of the 
attack, especially as no one had yet seen him dung. 
Treatment. — Gave ol. ricini §iij, tinct. opii 3v, spr. tereb. gij, 
in some gruel, and injected clysters of soap and water. In the 
course of an hour or so after the medicine had been administered, 
the foal commenced walking round the stable, and continued slowly 
to do so without intermission. 
6 P.M. — No better, and still wanders round the stable : the 
opium has, no doubt, produced the affection on the brain. Curls 
his tail about, and now and then continues to lift his hind legs up 
towards his belly. Gave Jij more ol. ricini. 
8 P.M. — About the same. Took four ounces of blood from him, 
and rubbed some mustard on the abdomen. 
6th, 8 A.M. — No better. Continue injections 
12 M. — Still wanders about, but he is evidently sinking. In the 
evening he died. 
Post-mortem examination. — At about four yards from the 
stomach I found that a foot of the small intestines was drawn com-
