A principle soluble in petroleam ether was present both in — 
the bark and wood, which yielded a bright red coloration with 
alkalies, the colour being changed to yellow by acids, and restored — 
‘by alkalies. A bitter principle was also preseut to which the 
taste of the wood is probably due, - In order to separate resins 
@ large amount of the wood was exhausted with alcohol of 85 
per cent., the alcohol evaporated off, water added to the 
extract, and the turbid mixture agitated with ether. During 
agitation chocolate-coloured flocks separated. The ethereal 
solation left on evaporation a reddish-yellow, soft, non-crystal- 
line, and somewhat bitter residue, The aqueous solution, after 
dissolved ether had been expelled, was filtered to separate the 
chocolate-coloured flocks already mentioned, and the filtrate - 
_ saturated with saltin order, if possible, to separate resin, but 
with negative results. The liquid was next agitated with acetic 
ether, the ether left on evaporation a slightly bitter principle, 
which was nearly wholly soluble in cold water. This principle, — 
and the chocolate-coloured resin, insoluble in ether, were — 
separately taken in doses of 0°1 ofa gram. without prodacing any 
purgative action. 
"The pulp of C. moschata is in the form of dry circular discs, 
similar to small gun wads, of a light yellow colour, with a seed 
loose in the centre ; it tastes astringent without auy sweetness. 
The pulp dried at 100° C. lost 7:26 per cent. of moisture; on 
incineration it yielded 5°77 per cent. of ash, the composition of 
which presented nothing peculiar. To rectified spirit the pulp 
yielded 20°66 per cent. of extractive; dried at 100° C, the 
extract was acid; after extraction with cold water the insoluble 
residue was 4°55 per cent. calculated on the extract. his 
residue on drying formed dark easily friable lumps, which 
gave a dark chocolate coloured powder. - In alkaline solutions 
it was soluble and was precipitated by acids in dark brown 
flocks ; it had the properties of an acid resin. ‘The aqueous solu- 
‘tion of the alcoholic extract was concentrated, and when cold 
saturated with NaCl, light brown flocks separated; the liquid _ 
_ was filtered and the precipitate washed with a saturated solu-
