OF ALCOHOL UPON DIGESTION.

gland lumina, ducts, and cannula was avoided.* After 

 collecting two or three control samples, the fluid to be 

 considered (usually warmed slightly) was injected into the 

 stomach in the manner already described, and this was 

 followed by a pause of five minutes. The pulse was observed 

 at frequent intervals to detect any possible influence on the 

 heart's action and consequent blood-flow. The samples of 

 saliva collected were analyzed in the manner already described. 

 At the conclusion of the experiment, the animal was killed by 

 bleeding, and the condition of the glands, as well as of the 

 stomach and other organs, examined. The protocols of three 

 typical experiments are given below. 



1, iii, 1897. Dog. Weight 14 kilos. Chloroform and ether administered 

 through tracheal tube during part of the experiment. Distance of sec- 

 ondary coil = 200 mm. Period of stimulation = 1 min., followed by a 

 pause of 2 min. 



Dog killed. Stomach mucosa normal in appearance. Urinary bladder 

 and gall bladder greatly distended. Stomach contents = 450 c.c., faintly acid 

 in reaction, and containing 24.6 grams of alcohol. No food present.

t In this first period the distance of the secondary coil was 280 mm., but 

 the stimulation was unsatisfactory.
