ribs, which are plainly seen to move under the skin. I could 
rarely, if ever, he certain of intercostal bulging being present 
as we see it in man under similar circumstances, but have 
generally observed that the intercostal spaces seem collapsed 
like other portions of the muscular system. Anasarcous 
swellings are mostly present in coarsely bred horses, but they 
are not always seen in well bred animals. The legs are fre- 
quently cold, but not so invariably. In tapping the chest 1 
have mostly found that fluid has passed from the opposite 
pleural sac into the one which was opened, so that after ob- 
taining a large quantity in a free stream from one side, (the 
right for instance), I could rarely procure more than a few 
ounces by piercing the other immediately after. This of course 
is explained by the percolation of fluid through the inferior 
mediastinum which does not in all cases become thickened like 
other portions of the pleural membrane ; it possesses in fact 
very few r vessels, and is areolar in health. 
In the case first reported, the quantity of fluid taken away 
at three times was 31 quarts. This is not a large amount ; 
we have often removed 20 and 25 quarts at one time. I 
recollect a mare walking a distance of tw r o miles to the Col- 
lege; she arrived at the dispensary hour one Sunday morn- 
ing ; water in large quantity was detected in the chest. The 
owner consented to an operation, and I removed 40 quarts 
at once from the right side ; only a couple of pints came from 
the left side. The mare was so much relieved that the owner 
took her home next day, and she died soon after. We now 
and then meet with recoveries after tapping ; as a general 
rule, how T ever, the operation merely prolongs life for a tem- 
porary period. 
HYPERTROPHY OF THE HEART AND ANEURISM 
OF THE AORTA. 
By Harry Daws, M.R.C.Y.S. 
A black charger, about ten years old, the property of 
Capt. Hare of the First Life Guards, was sent to the forge in 
the Regent’s Park barracks to be shod on the 9th Dec. That 
operation was completed in the usual manner, and the horse 
returned to his stables with a man on his back, kicking up 
his heels at every step : his corn was in his manger which he 
commenced eating with avidity, but suddenly the groom
