Some desirable results following water drinking with meals. 
By P. B. HAWK. 
[From the Laboratory of Physiological Chemistry of the University 
of Illinois.] 
In the continuation of our studies on the influence of water 
drinking at meal time, data have recently been collected as to 
the influence of this factor upon some of the activities of the 
gastro-intestinal tract. Particular attention has been given to 
the stimulation of gastric secretion, the activity of the pancreatic 
function, and to the course of intestinal putrefaction. As regards 
the stimulation of gastric secretion it has been found that the 
stimulation is directly proportional to the volume of water in- 
gested. The activity of the pancreatic function measured by the 
fecal amylase (Wohlgemuth's method) was found to be increased 
during the water period. At the same time intestinal putre- 
faction, as measured by the indican content of the urine (Ellinger's 
method) was decreased. Absorption was also facilitated and the 
excretion of fecal bacteria lowered when large volumes of water 
were ingested at meal time.

Metabolism after hypophysectomy.

[From the Department of Chemistry, Cornell University Medical 
College, New York City.] 
Three out of a series of respiration experiments on sixteen 
dogs, in which a part or the whole of the hypophysis was removed 
were reported. 
They represented: (1) Extirpation of part of the anterior lobe 
and all of the posterior lobe. (2) Removal of the anterior lobe, 
leaving the pars intermedia and the posterior lobe. (3) Complete 
hypophysectomy. 
The amount of gland destruction was determined by serial 
sections of the brain after the autopsy of the animals. Control 
experiments were made to determine the effect of the operative
