The solutions obtained were evaporated to dryness and the 
residue dried at 100° ©. and weighted. Each residue was then 
tested for alkaloids. The results may be tabulated as follows :—

No alkaloid was found in any of the residues. 
_ The residue from the chloroformic solution was slightly green 
in colour and contained long needle-shaped crystals sacle (or 
very sparingly soluble) in absolute alechol. The quantity was 
too small to allow of their further examination. 
The kernels were submitted to similar treatment. During the 
drying the colour changed from whitish to brownish, indicating 
that some change had taken place. The determination of the 
moisture is therefore unreliable and the figure obtained (1:56 per 
cent.) is not included in the table. ,

No alkaloid was found in any of the residues. 
The petroleum spirit extract was a pale brown, viscous oil. 
nm exposure to the air it rapidly formed a film on the surface, 
and on further exposure in a flat-bottomed dish it was converied 
into a whitish, solid mass, easily reducible to a white powder. 
This powder was now insoluble in petroleum spirit and the usual 
solvents for fixed oils. This behaviour is similar to that of, 
Chinese Tung Oil (from Aleurites cordata) which this oil also 
resembles in certain other of its characters. 
The chloroformic extract contained needle-shaped crystals, in- 
soluble in absolute alcohol, similar to those observed in the corre-
