58 REPORT—1874, 
Experiment 2.—Saturated solution of potassium acetate. 5 ¢.¢. were in- 
jected into the middle loop. 
On examination, 
Middle loop contained 8c. c. blood-stained turbid fluid with very little 
* mucus, 
= 7 5c. c¢. after filtration. Precipitated by HNO,. 
MRGEE os cana en 8 c.c. yellow.and turbid,

Mucous membrane :— 
Middle loop pale, covered with tenacious mucus; serous coat greatly 
injected, 
Upper ,, pale.

Experiment 3.—Saturated solution of potassium acetate. 23 ¢.¢. were in- 
jected into the middle loop. Weight of cat 2? lbs. 
On examination, 
Middle loop contained 15°5 c, ¢. of turbid fluid. 
Upper ,, empty. 
Lower ,, about 1c. c. of mucus. 
Mucous membrane :— 
Middle loop slightly congested, covered with flakes of mucus. The 
mucous membrane appeared very thin. 
Upper ,, normal; bile stained. 
Lower ,, soft, moist, covered with mucus. 
Experiment 4.—Saturated solution of potassium chlorate, Into the middle 
loop 24 c.c. were injected, 
On examination, 
Middle loop | each contained;13 c¢.c, of a fluid resembling white of 
Lower ,, } egg, both in colour and consistency. 
Upper ,, empty. 
Mucous membrane ;—

The fluid from the middle and lower loops was not coagulated by heat, It 
was rendered turbid by HNO,, and slightly so by acetic acid.

Experiment 5.—Saturated solution of potassium chlorate. Weight of cat 
3lbs. 23 c¢.c. of the saturated solution were injected into the middle loop. 
On examination, 
Middle loop contained ? c. c. of a grey muddy fluid.
