LXXXVIII. SOLANACE^. 



In the highlands of Huilla, where manioc does not succeed, the 

 common potato was introduced in 1840, and is extensively 

 cultivated by the negroes of Munhaneca in Humpata ; in 

 Welwitsch's time the potato disease had not appeared there. 

 After a prolonged diet of potatoes in Humpata, the Monanos, who 

 were quite unaccustomed to them, suffered from an outbreak of 

 dysentery. 



The Daturas appear to have immigi-ated from Asia ; they, as 

 well as hemp, have the Bunda name " Sambalage," derived from 

 dtlage, which means madness ; their poisonous narcotic properties 

 have been known to the negroes from the earliest times. 

 Welwitsch was convinced in several instances that the seeds were 

 intentionally used to produce poisoning, which in each case was 

 attributed to other poisonous plants known only to the negroes. 

 The drugging of palm wine with Datura, which is supposed to 

 be caused by the so-called " Fel de Jacari," supplies an emphatic 

 proof.
