prevent him from injury, in ease lie should not be able to get up, 
examination being postponed to the following day. He was 
found the next morning lying down, with the slings broken and 
in fact in a dying condition. Death takes place about 12 o’clock, 
and the post mortem was proceeded with immediately, having thus 
lost the opportunity of an examination rendered impossible and 
dangerous by the dying struggles of the patient. 
The subcutaneous tissue of the left leg is considerably con¬ 
gested, the lymphatic vessels and glands swollen, and the super¬ 
ficial veins dilated and gorged with thick and syrupous blood. 
The abdomen being emptied to render the examination of the 
main arteries easier, an aneurism of the great mesenteric is exposed. 
It is a large round mass, of the size of a good sized apple and 
entirely filled with an organized clot, composed of different layers 
which seem to close up the cavity completely. This clot ex¬ 
tends backwards into the posterior aorta, and thus obliteration 
is found in the left circumflex iliac, the external and the internal 
iliac of both sides, with however, some differences in the extension 
of the diseased process. It is thus that on the left side, the ex¬ 
ternal iliac is plugged way down, the clot being traced not only 
in the collateral branches but down to its termination into the 
tibial arteries and even below these as far as the hock. The in¬ 
ternal iliac on the same side is also obliterated, back into its ter¬ 
mination the obturator and iliaco-femoral; beyond those points the 
arteries seemed empty. On the right side, the internal iliac is 
also obliterated, but the clot scarcely reaches the terminal 
branches. The right external iliac is empty, but its coats are 
thicker and seem stronger than usual. 
The clot of the mesenteric artery is firm, hard, and composed 
of a whitish mass, well organized and more or less adherent to 
each other. The walls of the artery are thin ; some of the rami¬ 
fications of this trunk going to the small intestines, show also 
clots at different stages, here white, organized and hard ; there 
black or of red color and of more recent formation. 
The embolism of the aorta back to its termination varies also 
in aspect Forward to as far as the circumflex it is white, hard 
and composed of circular zones of old clotting of the blood, while
