forty seconds. An increased frequency of pulse did not indicate 
an increased rapidity of circulation. The hydrocyanate reached 
the same point in the same time, under very considerable variations 
in the number of pulsations. 
In a space varying from two to eight minutes it was secreted 
by the serous membranes, but in a small quantity. 
From the mucous membranes it was excreted more slowly, and 
in the following order:—the villous portion of the stomach, the

Where the mucous membrane was covered by an epithelium, as 
the eye, mouth, oesophagus, and cuticular portion of the stomach, 
no excretion could be perceived.

EXCISION OF A PORTION OF THE OMENTUM 
PROTRUDING FROM A WOUND. 
By Mr. J. Bean, of Stockton. 
ON the morning of the 4th of May, 1827, I was requested to visit a 
three-year-old mare, the property of Mr. H. a neighbouring fanner, 
which, to use the man’s own expression, had something hanging 
out of her belly. On my arrival, I readily perceived the pendulous 
substance to be the omentum, occasioned by a cow running her 
horn through the parietes of the abdomen, about three inches 
posterior to the cartilago ensiformis, and about two inches and 
a half on the left side of the linea ^rfba. The ])rotniding part 
(about twelve inches in length) was quite cold; one fold was 
agglutinated to the other by adhesive matter, and the blood vessels 
were turgid in consequence of the strangulation of the part. The 
pulse was sixty, full and compressible; and the mare e\inced no 
symptoms of pain. I removed with the knife all the protruding 
part of the omentum, and returned the strangulated portion into the 
cavity of the abdomen. I then placed a compress over the wound, 
retained in its situation by a broad flannel bandage round the
