DR. MARSHALL HALL’S 
deal of extravasated blood about the pelvic portion of the urethra ; 
on attempting to separate which, the bladder was left completely 
unconnected with the urethra ; and I almost fancy the urethra 
was corn through, but how it could be so injured, I can hardly 
tell, as the parts around, except about the bladder and urethra, 
were comparatively sound. Could it be produced when the blad- 
der is in a distended state, by suddenly pressing on it, and 
forcing it towards the diaphragm, and causing a separation from 
the urethra? The kidneys were highly inflamed, and the rami- 
fications of the bloodvessels were seen in a most beautiful 
manner. 
There were five principal arteries on each side of the kidneys, 
and each anastomosing with its fellow on the greater curvature. 
The ureters were dilated with urine to the size of a crow-quill. 
About thirteen inches from the stomach, there was a tape worm 
about four inches long, and attached at one end to the intestine. 
After it had been soaked all night in some water it was, I should 
think, ten inches long, and much wider and larger. 
On cutting open the bladder, it was found to contain a large 
quantity of reddish urine, and, on separating the coats of the 
bladder, the innermost coat or coats were completely gorged with 
blood, of a light venous hue, leaving the outer one comparatively 
of a natural colour. The rectum was nine inches long, the caecum 
two inches, and small intestines four feet six inches. The rectum 
and caecum had hard faeces in them. The stomach had only a 
few hairs in it, and not even a trace of mucus. There was a little 
bile in the two first inches of the duodenum, and the small in- 
testines had no food in them, and only a little mucus. 
The cause of his death, I should say, was probably from a 
rupture of the urethra, and the retention of urine was caused by 
the bladder being plugged up with inflammation and extrava- 
sated blood.

According to the views of Dr. Marshall Hall, from whose 
works these extracts are continued to be made, this act has never 
been properly or sufficiently explained ; nor could it, in fact, be 
in consonance with his notions, until his doctrine of excito-motorv 
physiology had become developed. In the opinion of our author,
