ON THE EXPANSION OF THE HORSE’S FOOT.

in Case I, on the morning of the 13th, the animal began to exhibit 
disease of the heart, and in association with it was a partial loss of 
consciousness, an association which, from the following, is common 
in the human subject, and proves, in a satisfactory manner, its 
identity in the two:—“ Patients labouring under rheumatic car¬ 
ditis very frequently become affected with delirium, or violent 
mania, or stupor and coma, or convulsions, or all of these in suc¬ 
cession : and you might suppose that they were labouring under 
inflammation of the brain or of its membranes. Such cases are, in 
fact, spoken of as cases of metastasis to the brain. It may some¬ 
times be so, nay, I know that it sometimes is so; but not often. 
Again and again, when death has occurred, and the delirium had 
been extreme, no traces of disease have been discoverable within 
the skull, while marks of violent and intense inflammation were 
visible in the pericardium. I presume that the acute cardiac affec¬ 
tion interferes somehow with that regulated supply of blood to the 
head which is necessary for the due performance of the cerebral 
functions. But whatever the explanation, recollect the fact; and 
whenever, in acute rheumatism, you will find your patient flighty 
and wandering, or more distinctly delirious, examine carefully the 
condition of his heart."*

SUBJECT the same as the preceding. 
A similar shoe was applied to the other fore foot, but the heels 
of the foot were now considerably cut away, so that there was a 
space between the shoe and the foot at that part. The inner sur¬ 
face of the upright iron was well oiled, and the angular space be¬ 
tween it and the hoof completely plugged up with prepared wax, 
which was pared even with the edge of the iron (this was done 
with the foot in the air). The horse was then made to support his 
weight upon the leg.

yielding of the foot downwards and backwards, until the heels of
