ON THE NATURE OF INTESTINAL SECRETION. 69 
A loop of intestine isolated close to duodenum and another at ileo-cacal 
valve. 
On examination, 
Duodenal loop 
Iliac 
There were some worms in the duodenal loop and none in the iliac. The 
latter was more contracted than the former. 
Vascularity of intestine normal. 
} both empty. 
Experiment 46.—Extirpation of right semilunar ganglion. It was cut out 
from the inner side of the right kidney. One loop of intestine isolated close 
to the duodenum and another at the ileo-cecal valve. 
On examination, 
Jejunal loop contained some worms, but was otherwise empty and dry. 
Iliac é i 3c. c. of fluid. Its mucous membrane was moist. 
Experiment 47.—Excision of left semilunar ganglion and upper two thirds 
of rigkt ganglion. Section of both greater splanchnics. 
On examination, 
Duodenum natural. 
Jejunum natural. 
Ileum pale. 
The mucous membrane of the isolated loop was moist and pale. The 
loop contained about 3 c. c. of fluid. 
There were no Z'enie nor Ascarides present.” 
Experiment 48.—Extirpation of both semilunar ganglia. Right semilunar 
was excised from the inside of the right kidney, and all the nerves attached 
to it were divided. 
One loop of intestine was isolated close to the duodenum, and another 
near the ileo-cecal valve. 
On examination, 
Duodenal loop contained 1 e. ec. of fluid. 
Iliac 43 4} c. c. of pale opalescent fluid. It effervesced 
and coagulated ‘with nitric acid. 
Mucous membrane :— 
Duodenal loop swollen, soft, pale. 
Tliae » pale. 
Experiment 49,—Extirpation of both semilunar ganglia, splanchnics on 
both sides divided, but some small branches of right great splanchnic not 
divided. 
One loop isolated close to the duodenum and another close to the ileo-cxcal 
valve. 
On examination both loops empty. 
Vascularity of intestines normal. 
Experiment 50.—Extirpation of both semilunar ganglia. The right gan- 
glion was reached from the inside of the right kidney. 
One loop of intestine isolated at the upper end of the jejunum and another 
at the lower end of the ileum. 
On examination the whole intestine looked large. Instead of the opposite 
sides lying flat against each other the intestine was round like a rope. 
Jejunal loop contained 1 ce. c. of fluid and some fecal matter. 
Iliac loop nearly empty.
