rent rock, in which it originally occurred : hence this kind of ore called Stream tin is 
much liner than what is broken immediately from the vein, because the action of 
the atmosphere and water decomposes, and carries off, the sulphurate and arseniates 
with which the ore was originally associated in the vein ; therefore, the tedious and 
pernicious process of calcination, by which the sulphur and arsenic are sublimed 
from mine tin ore, is not at all required for stream tin ore such as this, but it 
may be immediately put into the reverberator}' flowing furnace. 
The ore is found at a place called Ch.hando, near PSluk, about two days’ journey 
from the sea, halfway between Mergui and Tavoy. 
Captain Franklin who, our readers will remember, obtained the permission of Go- 
vernment, at the earnest recommendation of the Class of Natural History and Physics 
of the Asiatic Society, to proceed to Bandelkhand, the scene of his former labours, for 
the purposeof complctinghisgeological survey of that province, had reached MnngWr, 
on the 14th Jan. He found the rocks near Ritjinahl, Sikriguli, and Pir Painti of the 
trap formation. He was not therefore surprised to find Granite at Father Ghata 
and at Callgiton. Ho had made a pretty full collection of shells, and found amongst 
others Helix globosus, Vivipara fluviatilis, Planorbis, Helix Nautili, Anodonta, 
Iridina, and some Bulimi and Scalariic. These being crag shells, prove beyond a 
doubt, he thinks, that the hanks of the Ganges are posterior to the London clay. The 
season was adverse to his making any entomological collections, most of the insects 
being under ground, and the cold so intense as to have destroyed the butterfly; but in 
ornithology he had been more successful, and had, at thatearlv period of his journey, 
collected 40 specimens stuffed, and accu rately drawn and coloured after nature. This 
department of natural history is as yet untouched* in India, and offers a fine field 
to those who will devote themselves to it. Captain Franklin proposes to leave no 
means neglected of forming a complete collection of Indian birds. 
We shall be glad to learn further particulars of the researches of this able and 
zealous officer.

We do not think we are disposed to overvalue the utility of our work, when we 
say that by affording a means of ready communication between the several cultiva- 
tors of Science— not only in India, but between those of India and of Europe— it may 
often dimmish the labour of research, or dispense with it altogether. An instance 
has just occurred to us of this, in noticing which we shall have tile further gratifica- 
tion of ensuring to the gentleman, to whose assiduous zeal in the pursuit of science 
we owe so roanv interesting facts, that meed of fame which, as it is the principal, is 
also the most pleasing, reward the naturalist can look to.
