hydrochlorate of sanguinarina of a magnificent scarlet colour is ob- 
tained. ‘This salt, when dissolved in water, yields, on the addition 
of ammonia, pure sanguinarina in white or slightly coloured flocks, 
which become a yellow powder by washing and drying. 
Sanguinarina is insipid, occasions violent sneezing, and soon be- 
comes red in an atmosphere which contains even a small quantity of 
acid vapours. It is insoluble in water, very soluble in alcohol and 
ether; the alcoholic solution has a very bitter taste, and a mani- 
festly alkaline reaction. When heated it fuses, and has the appear- 
ance of an oil, and when burnt it leaves no residue. It neutralizes 
acids perfectly and forms red salts with them, which are very soluble 
in water, and possess very decided bitterness. Chloride of platina 
precipitates them of an orange-red colour, and infusion of galls of a 
yellowish-red. Concentrated nitric acid decomposes sanguinarina, 
and when dried at 212° it consists of

Hydrochlorate of Sanguinarina.—This salt, obtained by the process 
already indicated, is a red, agglutinated, friable mass; the powder, 
when examined by a microscope; appears to be an agglomeration of 
well-defined small crystals. ‘This salt is very soluble in water and 
in alcohol, especially when heated, but it is insoluble in ather,—

[We may take this as a suitable opportunity of remarking how 
much more simple and easy of application are the whole numbers 
which have been long used by many chemists in this country to 
represent equivalents than those generally employed on the continent ; 
and we trust that the able support given to the doctrine of whole 
numbers by M. Dumas, as quoted in our present Number, will have 
its proper weight both here and abroad. If we reckon that sangui- 
narina is constituted of equivalents represented by whole numbers, 
we shall have its composition as under :—

It will be observed that we have here 316 instead of 3973°48 repre- 
senting an equivalent of sanguinarina; in confirmation of the pro-
