subitaneae alvi excretiones faecum quasi succo viscido involutarum quae, 

 si continua per aliquot temporis serie sese excipiant, cum visibili 

 aesroti levamine, boni exitus pro indiciis habentur." Copious perspir- 

 ations follow, and these are succeeded by a gentle sleep. The violent 

 action of these roots renders them dangerous to employ, except in 

 cases of poisoning, or in such maladies as require a prompt and com- 

 plete evacuation of the intestines. They would possibly prove bene- 

 ficial in hydrophobia, in the opinion of Von Martius. It has been 

 introduced into European practice, and appears to be of the greatest 

 use as a remedy in dropsy. See an excellent account by Wood and 

 Bache, 2d edition, p. 200.
