INTUSSUSCEPTION OF THE INTESTINES. 
any means to overcome them — to which charge I must cer- 
tainly plead guilty. But I do hope, as I said at the com- 
mencement of my paper, that I may, by inducing a closer 
observation of the operations of nature, and a regular habit 
of recording them, indirectly, at least, add to our stock of 
knowledge on this most interesting inquiry. This is the 
utmost I proposed to myself, and all I can hope to accomplish. 
INTUSSUSCEPTION OF THE INTESTINES IN 
THE DOG. 
By T. Orme Dudfield, M.R.C.V.S., Cheltenham. 
A fine fox-hound puppy, nearly a year old, was brought 
to my infirmary on the evening of February 24th, being 
very ill. 
The most prominent symptoms present are a semiconscious- 
ness, associated with so much general weakness of the extre- 
mities, as to approach to paralysis; eyes dim and deeply sunken 
in the orbits ; mucous membranes slightly injected ; pulse 
rapid, feeble, and irregular; breathing but little disturbed ; and 
the general surface of the body warm. An offensive odour 
escapes from the mouth ; purging is also present, which is ac- 
companied with tenesmus, but the animal gives no other in- 
dication of pain. There is no desire for food. The patient is 
also much emaciated, and the skin is covered with a slight 
eruption. By pouring a little cold water on the head, the 
animal can be roused from his stupor, otherwise he lies ex- 
tended and quiet on his bed, seldom altering his position. 
Diagnosis . — Severe intestinal irritation, complicated with 
much derangement of the nervous system. 
Prognosis . — Unfavorable. A dose of the castor-oil mixture 
was administered. 
25th. — No improvement ; the alvine evacuations are ex- 
tremely offensive, of a dark chocolate colour, consisting almost 
entirely of blood and mucus, to the exclusion of solid or 
alimentary matters. Mucilaginous matters in a liquid form 
and diffusible stimulants were exhibited ; a seton was likewise 
inserted in the neck, and the head and abdomen blistered. 
26th. — Progressive weakness. Spasmodic twitchings in 
the right aural region are present ; the coma is also more 
complete, but it can be partially removed by cold effusions. 
The excrements are scanty and voided with pain. The
