68 REPORT—1874. 
Ruperiment 40,—Extirpation of the upper two thirds of right semilunar 
ganglion. Division of the right greater splanchnic. 
On examination, 
Duodenum 
Jejunum 
Lower part of ileum closely contracted. 
The loop of ileum 10 centims. long, which had been isolated, was empty. 
The part of intestine above the loop was full. 
The A) i below 35 empty. 
Experiment 41.—Excision of lower two thirds of right semilunar ganglion. 
Splanchnics not divided. One loop of intestine was isolated. 
On examination the intestines were found much contracted. Their dia- 
meter was only about half their normal one, and they were also contracted 
in the direction of their length. 
The loop, originally 10 centims., had contracted to 5 centims. The whole 
intestine was empty. 
Experiment 42.—Extirpation (complete) of right semilunar ganglion. In 
this operation the receptaculum chyli was wounded. The great splanchnic 
of the right side was divided in removing the ganglion ; the lesser splanchnics 
were unhurt. The animal was in full digestion, and the lacteals and recep- 
taculum were full of milky chyle. The cat was killed about four hours 
afterwards by a blow on the head. 
On examination the whole intestine was normal as regards vascularity and 
contraction. 
One loop of intestine (10 centims. long) had been isolated by ligatures at 
the time the ganglion was removed. It was situated 35 inches (89 centims.) 
from the pylorus and 18 inches (453 centims.) from the ileo-cxcal valve. The 
loop was distended with fluid. On measurement this amounted to 13 ¢.¢. 
The intestine above the loop did not contain more than 12 c¢. ¢. of fluid, 
although it looked full. The intestine below the loop was empty. There 
was no worm in the loop. The mucous membrane of the loop was normal. 
Experiment 43.—Extirpation of right semilunar ganglion. The right semi- 
lunar ganglion was excised as usual, and a loop of intestine 10 centims. long 
was isolated. On examination about four hours afterwards the whole intes- 
tine was normal as regards contraction and vascularity when the abdominal 
cavity was opened. 
After the cavity was opened the intestines contracted; after division of 
the mesentery they again relaxed, the loop, originally 10 centims., contract- 
ing to 7-5 centims., and again relaxing to 10 centims. 
The intestines above the loop were empty. 
Loop was empty. 
Intestines below the loop were full. 
Mucous membrane of loop pale, covered with bile-stained mucus. 
Experiment 44.—Extirpation of right semilunar ganglion. One loop of 
intestine isolated in the jejunum and another in the ileum, close to the ileo- 
crecal valve. 
On examination all the intestine was normal as regards both vascularity 
and state of contraction. 
Jejunal | 
_ Experiment 45.—Extirpation of right semilunar ganglion. The ganglion 
in this case was reached from the inner side of kidney. 
normal.
