POPULAR SCIENCE REVIEW. 
officer of tlie British Government;” and we are shown a photo- 
graph of one in his official robes. These “ Modliars ” are the 
chief exhibitors. They have sent specimens of oils, camphor, 
rice, carved-wood ornaments (one gentleman, who stands 
possessed of the name of Mr. Weiralasirinavana Absyaratine, 
exhibiting a beautiful piece of furniture of carved ebony), whilst 
the “ Ceylon Committee ” contributes the spices for which the 
island is so famous. 
A curious and most valuable substance exhibited in this 
coiu't, and which is also found in “ Queensland,” is the oil of the 
dugong, or lialicore, an animal allied to the seal. The oil is 
white and solid, and is employed for the same purposes as cod- 
liver oil, viz., as a tonic in cases of consumption, possessing the 
additional advantage of being entirely free from any nauseous 
properties, and devoid of taste or smell. It was introduced 
into England by Dr. John McGrigor Croft ; but beyond this Ave 
could gain no satisfactory information concerning its history. 
But we must uoav travel northward, crossing over to the con- 
tinent of India; and in the World’s Fair we are compelled to 
retrace our steps, and, once more traversing the transept, Ave 
must mount to one of its galleries. Here Ave shall find a most 
courteous and able expositor of the treasures of Inde in Dr. 
Forbes Watson; and onr readers shall have the benefit of the 
interesting information which he gave us concerning those 
products of the soil which now, more than at any previous 
period, possess such a deep interest for our countrymen. 
First of all, Ave are shown a kind of skeleton stand, composed 
of a series of circular shelves, situated oue above another, and 
in this are ranged 800 bottles, each containing the sample of a 
different groAvth of cotton ; and Dr. W atson further hands us 
an illustrative plate, shoAA r ing the lengths of the staple of cotton 
produced respectively from “native” seed, from “Ncav Orleans, 
or American,” and from “ Sea-Island and Egyptian ” seeds. 
Next in importance to the cotton culture is that of tea; and 
here, again, Ave are shoAvn a A r ariety of specimens, the number 
being almost incredible. 
Dr. A. Campbell, Avho collected these teas from the various 
provinces of India, shoAved us 142 different samples contributed 
by fifty estates. Of these the most valuable are the “Darjeeling” 
teas, from the Himalayas, of which 10,0001b. only have been 
produced this year; but the exhibitor stated that next year 
the quantity Avould, in all probability, be increased fivefold. 
Dr. Campbell values the finest Darjeeling tea at 2s. 8 cl. per 
lb., exclusive of the import duty. 
It is not generally knoAvn that the East Indian teas are of 
very strong flavour, and are chiefly used for mixing with the 
lower qualities of tea sold to our labouring classes. We, how-
