A CASE OF ANEURISM.

diminished the customary work for some days. Those of the 
horses who exhibited slight symptoms of disease he first bled, 
and then put under a course of tonics, and left them for some 
days to repose, and to a more substantial regimen. 
From that time the malady stopped, or very few horses were 
attacked. Out of the seven sick horses who were thus treated, 
one only died; the other six were cured, but it was a long time 
before they could resume their ordinary work. 
M. Renault is now writing an account of this disease, which he 
proposes to read at the Royal Academy of Medicine. 
A Case of Aneurism of the Right Auricle of the 
Heart, followed by Rupture of that Auricle in 
the Horse. 
By MM. Riss and Meyer. 
On the 5th of February, 1831, at the feeding time at four 
o’clock in the afternoon, we were called to attend a sorrel-co¬ 
loured horse about five years old, belonging to the 1st squadron ; 
received into the regiment the end of October, 1830, in a very 
bad condition, and in which state he had remained until this pe¬ 
riod. This horse, according to the report of the quarter-master 
for the week, had not eaten his morning provender, and he was 
cramped and lame in his hind extremities. After having atten¬ 
tively examined him, we remarked the following symptoms:— 
he was dull, the head low, the flanks tucked up: he staggered 
when walking, with his hind extremities wide apart; the pulse 
was small and quick. We desired that he might be taken to the 
infirmary, with orders to restrict his diet, and after that we 
resolved to wait until the morrow to fix on some rational plan of 
treatment, being far from expecting that which was about to 
happen. 
Towards six o’clock (that is to say, two hours after he had en¬ 
tered the infirmary), we were informed that he had suddenly fal¬ 
len down and could not rise again, and groaned very much. We 
went to him immediately: we found the animal stretched on his 
litter; his respiration was painful, almost approaching to suffo¬ 
cation ; his flanks heaving, his nostrils dilated; his eyes in a 
manner inverted in their orbits ; the mucous membranes appeared 
discoloured, and the pulse was small, wiry, and unequal. The 
hand being placed on the left pericardiac region, the violent palpi¬ 
tation of the heart was felt: the pulsations were sometimes so 
strong, as to be heard distinctly; and the body was covered with 
sweat.
