OBDER CVm. LOGANIACE^- 



The best known genus of this family is Strychnos, some of the 

 members of which genns are very poisonous. From the seeds of 

 Strychnos Nux-vomica, Strychnine is obtained, and the bark of the 

 roots of some other of the genus is highly poisonous. That of 

 ^>. Tieute, is used by the Javanese to poison their arrows, 

 and in South America two other species are similarly used, and are 

 supposed to be the most active ingredients in the '' Curare." S. 

 Ignatius yields the Ignatius bean of India, a supposed remedy for 

 Cholera, and S. potatorum bears the " Clearing nut " of India, which 

 clarifies the foul water placed in vessels whose inner surface has been 

 rubbed with this bean. The pulp surrounding the seeds of our native 

 tree S. Gerrardi, popularly known as " Gulugulu," is eaten by natives 

 and children, and the bark of another species is used medicinally by 

 the natives. The wood of another species S. Atherstonei has been 

 used for staves of casks, but it is not of much value. That of Nuxia 

 iloribunda is used by wagon makers, and that of Buddleia salviiejulia 

 is hard and strong, and is t-aid to be suitable for wood engraving, and 

 excellent for wood type ; but the tree is not of large size.
