8,759. Specimen of Sohägä (borax).
Sohägd, or borax, is also called tincal. It is
obtained in large quantities in the valley of Pega,
in Ladakh, and in Thibet; it is collected on the
borders of the lakes as the water dries up, then
smeared with fat to prevent loss by evaporation, and
transported across the Himalayas on the baeks of
sheep and goats; refined at Umritsur and Lahore
by washing with lime water. It is employed by the
natives as a tonic for loss of appetite; also as a
deobstruent and dinretic in aseites; and also to pro-
mote labour. It is used in the arts to clean metals
before soldering, to form a glaze on earthenware, and
in the preparation of varnishes. It is employed as a
Chemical flux in experiments with the blowpipe. It
is in composition a biborate of soda. Price of raw
borax, 4d. per lb.; of refined borax, 6d. per lb.

B.—ETHEREAL OILS AND PERFUMERIES.
Of scented oils there are two kinds found in Indian
commerce, the one, being the cheapest, is a fatty oil,
such as that of Sesame, scented with the odour of
roses, jasmine, and other plants. The other scented
oil is an essence or attar, obtained by direct dis-
tillation. Of course this latter varies in quality and
purity, very many samples of attars being more or
less adulterated with fatty oil. Pure attar is a strong
volatile oil, and commands a high price. In Europe
the attar of roses is best known and most highly
esteemed; the purest and richest in India is manu
factured in the neighbourhood of Ghazeepore.
Other “ perfumeries ” obtained from India are the
raw materials of perfumery, such as scented woods
and dried plants in the vegetable, and civet and musk
in the animal kingdom. In addition to these may
be mentioned scented powders, pastiles, and other
preparations.
