Tlie fruit of this tree is hitter sweet aiul is eaten by the natives. It is of about the 
size ami general appearance of a dried date and consists of a thin brittle shell enclosing a 
mass of ginnniy consistence surrounding and firmly adherent to the stone. The latter is 
very hard and tough and contains an oily kernel.

The oil is highly prized by the natives and would be extracted on a much larger scale 
were it not for the very great difficulty which is experienced in separating the kernel from 
the tough, hard nut. 
Chemical examination of the oil gave results as follows :—■

This oil, obtained from the seeds of the lintiini^pormum. parliii, is known in Europe 
under the names of “Shea butter’’ and “ Galam butter.” Considerable quantities have 
been imported into Europe from West Africa. The crude oil, as extracted by the native, is 
principally used in Enrope, for candle and soap-making. The refined oil is employed in the 
manufacture of oleo-margarino and similar products. 
The following are the results of examination of two samples of the oil from the Bahr- 
El-Gliazal Province. Both of these were of rather dirty appearance and dark colour, but 
were readily purified by heating with a small amount of animal charcoal, followed Ijy 
filtration, both taste and colour being improved to a marked extent.

These figures are in general agreement with those yielded by “Shea butter” from 
other localities.
