to anthrax; he believed it was due to submucous haemorrhage, or 
an apoplectic condition of intestine. 
Mr. Field observed that he had recently met with a similar 
case in a pony, which had just before returned from a ride. 
He had not seen it alive; in this instance the stomach also 
had bled. 
Mr. F. J. Mavor said that, with the probability of an outbreak 
of cholera in England, such a case as this should be made known 
in medical circles, as it bore an analogy to that disease. Having 
seen the case during life he took that view of it, from the fact of 
the horse eating well, yet, suddenly perspiring, the other symptoms 
as quickly ensued; the fseces that were removed from the intestines 
he explained were most foetid. 
The President thought the remarks of the last speaker should 
be well considered; choleraic fseces, he explained, were white, not 
sanguineous. 
Mr. Woodger , jun., instanced two cases in one establishment, 
where, after colicky symptoms and quick death, the mucous 
membranes of the intestine were found distended and much 
thickened. 
Messrs. Moore and Hunting considered the specimen simply the 
result of inflammation of the bowels; but it was shown that there 
was no serous effusion or exudation of lymph, peritoneal inflam¬ 
mation, or pain, because the nerves were paralysed. 
The President then called on Mr. E. J. Mavor to read his paper 
on “ Animal Heat and Rise of Temperature from Disease/'’ He 
read as follows : 
“ It is a well-established fact that a living animal body is con¬ 
stantly eliminating heat from the elements of nutrition to keep 
the blood up to a certain fixed normal temperature, however 
much it may differ in the different species of the same class; for 
instance, among the mammalia, man has a temperature of 98°, 
the horse 100°, the ox 101°, the dog 103°, goat 103°, fox 101°. 
But the animal heat, or, what it might be more properly called, 
the natural gas or atmosphere of the body, performs very im¬ 
portant functions; namely, it is essential to the fluidity of the 
blood and elasticity of the tissues, by separating the globules and 
fibres, and it is its absence that allows the blood to coagulate 
and the body to lose its elasticity after death; it is also the source 
from which the nerve force is derived. To explain this I must 
call your attention to the fact of correlation of forces, i. e. heat, 
light, electricity, chemical force, motion, &c., may each be con¬ 
verted to and produce the other; as heat in the steam engine 
produces motion, so animal heat produces or is correlated into 
nerve force—in other words, muscular action, secretion, circu¬ 
lation of blood, and all the functions essential to life. My present
