POPULAR SCIENCE REVIEW. 
quantity of the so-called colza oil, imported from France and 
Belgium, is made from the seed originally brought from India 
to London and Liverpool, and thence re-exported to those two 
countries. How important must our colonics be to our welfare, 
when we find that the continental nations which supply us with 
food for our lamps come to England to purchase, for this pur- 
pose, the raw material which is brought from our own distant 
settlements. Besides the two already named, there are many 
other seeds yielding oil. Of these the chief are, teel, or gin- 
gelly, a small white and black seed; niger, a bright black 
seed ; poppy, ground-nuts, &c. &c. As to the products made 
from these seeds, if cattle could speak, they would probably tell 
us that they frequently observe indications of the presence of 
the inferior cakes made from some of them in their linseed cake ; 
but, as they cannot, that will remain a profound secret. 
We, however, have suspected the presence of the oils, which 
are for the most part colourless, and are largely used in France 
and the Mediterranean, in the olive oil ; and wicked persons are 
in the habit of asserting, in the most barefaced manner, that 
they are largely employed for the purposes of adulteration. 
The mineral products of India are not conspicuous, and the 
coal, of which there are the representatives of the five different 
fields now worked, is of inferior quality, and suited only for 
river steamers. 
The specimens of silk, wool, and other animal products, are 
of the first order ; and these lead us into what is, unfortunately 
for us, forbidden ground. 
It does not come within our sphere to speak of the exquisite 
works of art which give such eclat to the Indian Court, — of the 
ornaments in silver and gold ; of woven fabrics of such delicacy 
as to be almost transparent, and which are trimmed with gold 
and silver lace equally delicate. Nay, the further we venture 
into this court the more seductive does the exhibition become. 
These gorgeous ornaments of gold and silver ; these caps and 
crowns, fans and punkahs ; this beautiful carved furniture ; these 
richly jewelled and inlaid arms ; and such Cashmere shawls, 
gold- embroidered purses, caps, and slippers ! . . . . but 
we must proceed no further, and, with a well-merited compli- 
ment to Dr. Forbes Watson, for what we consider the most 
perfectly arranged of all the colonial courts — and that is saying- 
much — we must now bid adieu to the wealth of India, and 
hasten onward to 
Natal. Although we cannot tarry long in this court, we have 
time to inspect the interesting model of a Kafir kraal, or encamp- 
ment fortified against wild beasts, and equally wild inimical tribes. 
Or we may imagine ourselves for the moment to be emig-rants, 
and examine with interest the bush waggon and its appendages,
