and 60 per cent, of kernels. The oil gave 60 per cent, of liquid oil and 40 

 per cent, of white solid fat. Seeds from Northern Nigeria contained 334 per 

 cent, of oil. Meggitt (1907) obtained 25'65 per cent, of oil in the sweet variety 

 and 22-62 per cent, in the bitter variety. 



Lewkowitsch expressed the seed in two stages and obtained a cold pressed 

 and a hot pressed oil. The examination of these two oils gave the following 

 numbers : Specific gravity at 40°, 09018, 0-8984 ; acid value, 4971, 100-5 ; 

 saponification value, 179 - 5, 1787 ; unsaponifiable matter, 1 67, 2 69 per cent. ; 

 iodine value, 100*3, 88 ; titer test of fatty acids, 32°, 38-2°. 



Ben oil is said to consist of the glycerides of oleic, palmitic and stearic 

 acids and of a solid acid of high melting point, probably arachidic acid. (Agri- 

 cultural Ledger for 1911-12 No. 5 p. 136).

 cence. Bark thick, soft, corky. Wood white, soft, Pores large, 

 often sub-divided, enclosed in white rings, scanty. Medullary 

 rays fine, numerous, the distance between them less than the 

 diameter of the pores (Gamble;. Leaves generally bipinnate, 

 very rarely tripinnate, reaching 1£ ft. long. Primary pairs

 base as well as the secondary articulation, with a gland at 

 each articulation. Leaflets 4-6 pair, with an odd one, broadly 

 elliptic or sub-orbicular, obtuse at both ends, often retuse at 

 the apex, of variable size, |-1^ by J-l in., pale beneath,
