Notre.—The above two mineral substances are the natural productions of Behar 
and Nipal. They might be used largely in the arts, especially in the manufacture 
of Prussian-blue, Calico printing, and Dyeing; I am not aware that they have 
been noticed by European Chemists. If they have, the notice has escaped my read- 
ing. I am informed that they may be had in large quantities, the Sulphate of Iron 
in particular. The specimen which I operated upon was purchased from Patna 
Bazar, where depots of this mineral are established.

The plants were subjected to calcination, similar to the method used 
to make kelp in Scotland, and the quantity of alkali ascertained by 
Brande’s process. 100 parts contained as follows :

* The latter plant, called by the Natives of Tirhit Gada Purna, is much used 
by the Dhobis or native washermen. They collect and subject it to the opera- 
tion of burning, using the ashes instead of soap. Iam not acquainted with the 
botanical name of this plant, having never seen it in flower. It is almost unne- 
cessary to add, that the alkali from the above plants is sub-carbonate of potass.
