ON WOUNDS PENETRATING INTO THE CHEST. 69 
offered to him, and he even seized it greedily while, he was lying 
down. At 10 o’clock he was still lying down ; he breathed with 
oreat difficulty, and the souhresaut of broken wind was evident. 
On the following morning he w'as still lying; the respiration 
w'as more accelerated, and the souhresaut more marked. In the 
evening he had not got up; his mouth was open; his nostrils 
dilated beyond measure: no vesicular respiration, but we heard 
only a puffing sound towards the end of the expiration. 
The horse died during the following night. 
He was examined at half past eight on the morning of the 
following day. The left pleural sac contained about two quarts of 
bloody serosity, with a firm and yellow clot floating in it, about 
the size of a fist. Other little fibrous clots adhered to the pleural 
covering; there w^as no trace of vascularity in them, but the sub- 
pleural cellular tissue, both costal and pericardic, was strongly 
injected. 
The left lung did not fill more than a third of its proper cavity. 
Its costal surface was rugous at several points. The rugosities 
were attributable to an infinity of false membranes, formed on 
the pleura. The portions of the lung which corresponded with 
these granulations were condensed and highly red Their inter- 
lobulaiyand sub-pleural tissue was infiltrated : in a word, it was 
the seat of pneumonia, which extended deeply into the lung, but 
which was not by far so intense as the inflammation on the pleura. 
The right lung was not inflamed. The pleural sac on that side 
contained a little bloody fluid, but no false membranes. 
Into the chest of a third horse we introduced about two quarts 
of water, at a temperature of 8 (50 Fah.) degrees; but, for a 
reason which it is scarcely worth while to report here, we could 
not detain the horse more than two houis after the experiment. 
During that short space of time we perceived that he had a shi¬ 
vering fit; that he pawed with his foot; and that he continually 
lay down, and got up again, as if he had colic. These two 
last symptoms, which we thought rather extraordinary in this 
case, have constantly appeared whenever we have injected alcohol 
and saline solutions into the chest. 
1:2. Simple Hounds of the Parietes of the Chest, with the In¬ 
jection of Alcohol. 
The symptoms and lesions which follow the injection of alcohol 
into the pleural sacs are analogous to those produced by the in¬ 
jection of a considerable (piantity of water; only they appear, 
and attain their utmost intensity with greater rapidity, and the 
animal sooner dies. Alcohol always produces ])neumonia, ])leu- 
risy, and ol’ten pericarditis when the patient lives two or three 
days. The only peculiar circumstance which we have remarked
