dusky cinnamon colouring matter which also contains tannin, and for 

 this reason is frequently employed with complete success by the 

 Mossamedes fishermen for staining their nets and preserving them for 

 a long time from decay. Thunberg spoke of the plant as a fungus ; 

 and in his time it was known in South Africa by the name of " Jackhal's 

 Kost." See Thunberg's Travels, Engl, ed., ii. p. 133 (1795). For a 

 further account of this underground parasite see Monteiro, Angola, 

 ii. p. 207 (1875).
