10. “Euonymin,” an impure resinous matter prepared from the 
bark of Euonymus atropurpureus , is a powerful hepatic stimulant. 
It is not nearly so powerful an irritant of the intestine as 
podophylline. 
11. “ Sanguinarin,” an impure resinous matter prepared from 
the Sanguinaria canadensis , is a powerful hepatic stimulant. It 
also stimulates the intestine, but not nearly so powerfully as podo- 
phylline. 
12. “ Iridin,” an impure resinous matter prepared from the root 
of Iris versicolor , is a powerful hepatic stimulant. It also stimu- 
lates the intestine, but not so powerfully as podophylline. 
13. Leptandria is a hepatic stimulant of moderate power. It is 
a feeble intestinal irritant. 
14. Ipecacuan is a powerful hepatic stimulant. It increases 
slightly the secretion of intestinal mucus ; but has no other appa- 
rent stimulant effect on the intestine. The bile secreted under 
the influence of ipecacuan has the normal composition. 
15. Colocynth is a powerful hepatic as well as intestinal stimu- 
lant. It renders the bile more watery, but increases the secretion 
of biliary matter. 
16. Jalap is a powerful hepatic as well as intestinal stimulant. 
17. Sodium sulphate is a hepatic stimulant of considerable 
power. It also stimulates the intestinal glands. 
18. Magnesium sulphate is an intestinal but not a hepatic stimu- 
lant. 
19. Potassium sulphate is a hepatic and intestinal stimulant of 
considerable power. Its action on the liver is, however, uncertain, 
probably owing to its sparing solubility. 
20. Sodium phosphate is a powerful hepatic, and a moderately 
powerful intestinal stimulant. 
21. Eochelle salt is a feeble hepatic, but a powerful intestinal 
stimulant. 
22. Sodium chloride is a very feeble hepatic stimulant. 
23. Sodium bicarbonate has scarcely any appreciable effect as a 
hepatic stimulant. 
24. Potassium bicarbonate has scarcely any appreciable effect as 
a hepatic stimulant.
