A CASK OF INTROSUSCEPTION IN A FOAL. 
It was that of a cow having a large tumour in her axilla, which 
had existed for some length of time previously to my being sent 
for, without producing any degree of lameness. The tumour 
had continued to increase, until, by the time I was called upon 
to examine it, much lameness had ensued. The tumour was 
hard and hot, exhibiting a considerable degree of sensitiveness, 
and fluctuating to a small degree. 
I inserted a seton through the pectoral muscles from above 
downwards, which was attended with good effect. Afterwards, 
when I was in the act of dressing the seton, there protruded 
between its orifices something very sharp, which, on extraction, 
proved to be a darning-needle with the point outwards, and about 
three inches in length. I treated the abscess in the common way, 
and the cow was ultimately restored to health and soundness. 
The query arising in this case is, How did the needle get 
there ? There is no improbability in the supposition that the cow 
must have swallowed it in the act of feeding, and that it made 
its way through the esophagus towards the axilla, where the 
tumour had its seat. 
[The existence of sharp-pointed foreign bodies in various parts 
of the frame is a circumstance of frequent occurrence, and 
much inflammation and pain are usually produced as they are 
performing their strange journey towards the surface of the 
frame. It is singular with what unerring skill the nerves and 
bloodvessels seem to be avoided. A certain degree of pain 
usually accompanies the whole of the journey, but very little 
injury is done to the neighbouring tissues. — Y.] 
A CASE OF INTROSUSCEPTION IN A FOAL. 
By Mr. Alfred Walker, F.S., Southam. 
I was sent for on the 5th of the present month, at six o’clock 
in the evening, to a cart-colt, five weeks old, the property of 
Mr. Machen, of Gibraltar-House, near this town. I found him 
in great agony, having, at first sight, the symptoms of spasmodic 
colic. He had been in that state three or four hours. On making, 
however, a more minute examination, I concluded, from the fol- 
lowing symptoms, that it was a case of enteritis, brought on, 
probably, by some displacement of the intestines, the nature of 
which I explained to the owner. 
The animal was continually lying down and getting up again
