RUPTURE OF THE DIAPHRAGM IN A MARK. 2U 
The immediate cause of death was indistinct and unsatisfac- 
tory — it was the formation of fibrous matter, closely adhering to 
various portions of the heart, and especially over the right ven- 
tricle. There did not appear to be any adhesion between it and 
the loose pericardiac membrane. On the left ventricle was a 
smaller portion of this morbid growth, and a little of it in the 
inner parietes of both ventricles. It was a morbid growth which 
I do not recollect to have seen before ; and I can easily compre- 
hend that, to a certain degree, it must have interfered with the 
action of the heart, and been an indirect cause of debility. 
The slight trace of tubercular disease — was it the commence- 
ment of phthisis, or was it the remains of that disease yielding 
to a three months’ course of iodine ? 
We have an Orang-Utan that has been with us more than a 
twelvemonth, and has gradually got rid of an apparently phthisical 
cough that threatened to destroy her. Our quadrumana gene- 
rally are beyond all comparison more healthy than they used to 
be. Their habitation is better ventilated, and the slightest cough is 
treated by a small antimonial emetic. If it does not yield to this, 
a course of iodine immediately follows. Two years ago we lost 
all our quadrumana, and all exhibiting in various degrees the 
ravages of phthisis. Since that period not one has died of tuber- 
cular disease, and scarcely a trace of incipient phthisis has ap- 
peared in any of them, with the exception of these chimpanzees. 
We will not draw any hasty conclusion; but, if our readers 
will permit, will oflener attempt a slight sketch of these inferior 
divisions of quadruped pathology. 
RUPTURE OF THE DIAPHRAGM IN A MARE. 
By Mr. W. Ernes, F.S., London . 
On the 9th of March, about 8 o’clock in the morning, my 
attendance was required to a grey mare, of the cart-horse breed, 
aged eight years. There was no indication of illness on the pre- 
vious evening ; but in the morning she was found not to have 
consumed her usual quantity of provender, and refused the water 
that was presented to her. She appeared to be uneasy, and 
threw herself down violently. 
On my arrival, l found her circulation but slightly increased — 
respiration normal — the visible mucous membranes pale — the 
mouth clammy — the tongue coated — the general temperature of
