466 STRANGULATION OF THE INTESTINES IN A HORSE. 
the horny and living or vascular (if we may use the term 
when no blood-vessels are discernible) leaflets, there appears 
to be a cellular material, composed of one or more layers 
of soft diaphanous cells, containing a nucleus, and even a 
nucleolus. These cells offer a high degree of permeability 
to the carmine fluid. 
Such, then, are the relations between the keraphyllous 
and podophyllous tissues of the horse's foot. The dove- 
tailing or engrenure, it will be understood, is of the most 
complicated, but, at the same time, most wonderful descrip- 
tion, and presents features which were never dreamt of by 
those who, even in recent times, had made this organ their 
particular study. 
STRANGULATION OF THE INTESTINES IN A 
HORSE, CAUSED BY CARCINOMA IN THE 
MESENTERY. 
By M. J. Roberts, M.R.C.V.S., Ackworth, near Pontefract. 
Having had rather a singular case brought to my notice 
last April, I send you a brief history of it, thinking it may 
be interesting to the readers of the Veterinarian. On Thurs- 
day, the 27th April, I was requested to attend at Mr. Ellison's,

the natural heat ; pulse 60, and rather full ; visible mucous 
membranes of a yellow hue, but not injected. When the 
rectum was explored she strained immensely, but nothing 
was found in it. I gave aloes Barb. $v cum colic, haust. :

April 28. — Pain not relieved ; pulse 72, harder, and not so 
full ; ears and extremities rather cold ; urine scanty and high 
coloured; visible mucous membranes slightly injected. I 
again backraked the animal, and only found a piece of dung 
the size of a walnut. Constantly severe straining, with 
anxious looks at the abdomen, still existed. Stimulating 
liniment was applied to the abdomen, and enemas thrown
