Necropsy.—The rhubarb had extended along about a third of the small 
intestine. There was no unusual redness of the mucous membrane, and there 
was only slight evidence of purgative action.

the secretion, of short duration: 5 cc. of the same infusion of rhubarb as that 
used in the previous experiment were injected into the duodenum three times 
in succession (7, 7”, 7”, fig. 14). The biliary secretion was augmented within 
half-an-hour after each injection. 
Necropsy.—The rhubarb had extended along four-fifths of the small 
intestine. There was no unusual redness of the mucous membrane. The 
portion of intestine through which the rhubarb had extended contained 120 ce. 
of a thick yellowish fluid: there was, therefore, decided evidence of purgative 
action. 
The amount of water given with the rhubarb in these experiments was so 
trivial that it may be entirely disregarded.
