standing no crystalline deposit was formed ; there was nothing 
specially noteworthy regarding its colour reactions. No alka- 
loidal principle was detected. The ethereal extract was whitish 
and oily ; in light petroleum ether *52 per cent. was soluble, 
which added to the petroleum ether extract, would increase 
the oil content of the kernels to 30°44 per cent. ; the resi- 
due insoluble in light petroleum ether amounted to ‘09 per 
cent., and did ‘not afford reactions for alkaloidal principles. 
Brannt states that the oil behaves in the same manner as 
mastic oil when obtained by expression, and he describes it as 
a green fluid oil, from which a white fat of the consistence of 
butter separates.

The alcoholic extract was whitish and partly soluble in hot 
water with acid reaction, tasteless; no alkaloid was detected. 
The aqueous extract did not reduce an alkaline copper solu- 3 
tion until after boiling with a dilute acid. The extract was _ 
specially examined for saponin with negative results. 
The powdered air-dried bark ofthe large variety of 7’. belerica 4 
contained 3°71 per cent of moisture, and 18°61 per cent of ash, 
in which no trace of manganese could be detected. 
With the exception of astringent matter, giving a brownish — 
coloration with ferric salts, nothing of special importance was — 
detected in either the bark or leaves—no alkaloids or glucosides _ 
were detected. An alcoholic extract, after separation of th 
alcohol, obtained from 10 grams of the bark injected into a — 
cat’s stomach, afforded the following symptoms :— 4 
Injected at 10-50 a. m. into a cat’s stomach which had fasted j 
for about 10 hours. 4 
11-15. Vomited twice. 
11-25. Solid motion. 
11-45, Vomited. 
No further symptoms were noted, and the following day the 
cat appeared to be in its normal condition. 
In the case of the leaves an alcoholic extract induced almo 
immediate vomiting without any other symptoms,
