The oil immediately after extraction was liquid and with a 
ereen colour. It solidified on standing overnight and had the 
appearance of a tallow with a distinct odour of cocoa butter. The 
fat was found to have a very low acid value, the actual figure being 
Orgas. 
The embryo has its cotyledons shghtly unequal as in the 
following drawings where two are seen from the placentar side: 
the outer cotyledon is seen to be by a little the larger and alone to 
reach the very apex of the fruit-cavity. Great irregularity was 
found in the embryo: for instance in figure 4 one lobe of the 
placentar cotyledon is crossed partially to the wrong side of the 
dissepiment, and in figure 9 the two cotyledons are seen to be

seed coats. No. 4 is slightly abnormal in that one or the lobes of the 
placentar cotyledon has trespassed upon the room of the other lobe. %

uneven. Normal expanded cotyledons are as in figures 6 and 7: 
in outline they are quite typical of the genus Shorea. Figures 8 
and 9 represent the seedling, figure 8 a normal individual,—but 
Figures 6 and 7, the expanded cotyledons of a seedling, No. 6 is the 
placentar cotyledon seen from the side towards the outer cotyledon; fig. 
7 is the outer cotyledon from outside. Figures 8 and 9 two seedlings, the 
latter abnormal as a result of injury (? insect-puncture) at the point of 
the arrow. All 1% nat. size.
