accumulation of wind, rupture is succeeded by relief. The restlessness and 
straining subside, and a period of calm follows, until death results. The 
countenance is anxious. The pulse is small and thready, and gradually 
‘becomes more and more imperceptible. The breathing is short. There is 
great disinclination to stir. 
In rupture of the large sacculated bowel, the horse frequently sits on his 
haunches, and may attempt to vomit ; but these symptoms cannot be said 
to be characteristic. Sitting on the haunches, indeed, is a very frequent 
symptom in twists and other forms of disease of the bowels. Treatment is 
of no avail in rupture of the bowels. 
DYSENTERY. 
DYSENTERY is of less frequent occurrence in the horse than in the other 
domesticated animals, and, owing to the comparative rarity of its appearance, 
it is hardly necessary for us to give our readers a lengthy account of its 
characteristics. It has not yet been established whether this affection can 
be communicated from one horse to another, but it is not improbable that it 
may sometimes spread in this way. In most cases dysentery occurs as an 
independent affection, while sometimes it supervenes on an attack of ordinary 
diarrhoea. Among the chief causes of dysentery are overcrowding, vitiated 
air supply, exposure to noxious emanations, insufficient or bad food, foul 
water, exposure to cold and damp, overwork, and all other depressing 
agencies. Malarial poison arising from decaying vegetable matter, is also a 
common cause of dysentery. This is more especially the case in low-lying, 
marshy tracts, and in shady places. Sometimes dysentery begins insiduously, 
in which case we may at first not suspect the true nature of the affection. 
As the disease progresses, however, the appetite becomes more markedly 
impaired. Great depression and thirst, general wasting, and severe 
prostration are marked features. Usually the attention is first attracted by 
the frequency of the alvine discharges, but not unfrequently febrile 
manifestations, debility, and rapid prostration precede the other symptoms. 
These discharges are thin and watery, and are sometimes voided with great 
pain, and in most cases there is much straining. - 
Mild cases of dysentery usually terminate in recovery, but in severe 
ones there is not much hope of amelioration. In the treatment of dysentery, 
it is at first necessary to attend to the sanitary arrangements. The animal 
should be kept at rest, and the diet should be of an easily digestible, fairly 
nutritious, moist kind. A small dose of oil, say three-quarters of a pint of 
linseed oil, may be given in the first instance. This should.be followed up 
by the administration of drenches composed of one ounce of tincture of 
opium, two drachms of camphor, half an ounce of nitric ether, half an ounce 
of bicarbonate of potassium, with water to ten ounces. These drenches may 
be given twice daily. If the progress of the disease be not arrested in a few 
days, astringent medicines will be necessary. In such cases, eight drachm
