liquid, the aqueous solution of which was very acid and had an 
odour of butyric acid. A tincture of the root was red in colour, — 
astringent to the taste, and very acid in reaction. Evaporated — 
to dryness and heated with water, the solution gave evidence — 
of a tannin by giving a green precipitate with ferric chloride, 
pinkish with gelatine and bulky brown with iodine. The in 
soluble portion yielded to petroleum spirit one or more fatty — 
acids, liquid at 20° C., and the red precipitate insoluble in 
this medium was eelubio in spirit and soda solution, and con-— 
sisted of oxidized tannin. A white erystalline substance was 
associated with the tannin in the aqueous solution of the 
alcoholic extract, and gradually formed in small quantity whe 
the evaporated solution was set aside for a few days. The 
flowers have the delicate odour of cinchona flowers, and ¢ 
The aqueous solatioy is ‘einclechied by ferric chlomaiau precip 
tated by gelatine, destroyed in brilliancy by fixed silabead a 
restored by acids. Ammonia renders the solution dichromatic, 
and lead acetate throws down the colouring matter 
greenish blue precipitate, containing 32:9 per cent. of oxide 
Ether removes a wax and a yellow colouring matter related t 
quercitrin. Alcohol and water respectively remove from 
drag the same amount of extract, namely, 30 per cent., con 
ing largely of saccharine matter. The astringent colo 
matter occurred to the extent of 5°7 per cent., and the pap 
used in filtering the solutions retained a small quantity of 
colour, which changed to blue by exposure to the air, and 
paper acted as litmus in turning red with the least trace 
acid. The ash was 6:4 per cent. | 
The flowers of Ixora parviflora, Vahl., the Torch | 
pounded in milk, are given for whooping congh, and at th
