88 DIPTEROCARPE^. 



The fat of the seeds of G. inclica was extracted by ether and examined 

 chemically in 1857 by J. Bouis and d'Oliveira Pimentel.^ It ^vaJ 

 obtained to the extent of SO per cent., was found to fuse at 40° C. 

 and to consist chiefly of stearin (tristearin). The seeds yielded r72 per 

 cent, of nitrogen. Their residue after exhaustion by ether aflforded to 

 alkaline solutions or alcohol a fine red colour. 



Uses— The results of the experiments above-noted show thatkokuffi 

 butter is well suited for some pharmaceutical preparations. It might 

 also be advantageously employed in candle-making, as it yields stearic 

 acid more easily and in a purer state than tallow and most other tats. 

 But that it is possible to obtain it in quantities sufficiently large tor 

 important industrial uses, appears to us very problematical.
