succeed effectually in salt water also. Nay, even naked wires after having been used for about an hour as conductors in salt water are, I find, protected or insulated by the coat of oxychloride of copper, which forms on the positive wire.
In subsequent experiments I would recommend a copper or sheetiron, water-tight, tube to be soldered round the internal orifice of the screw plate into which the explosion tube is inserted (see fig. 10 c, c, c,) This would constitute a separate compartment in the mine or cylinder, and in the event of leakage, that portion only of the powder could be spoiled contained within this tube. This alteration I have taken the liberty of recommending to Captain Fitzgerald and Lieut. Smith, the engineer officers employed in these operations.

14 Grafton Street, Bond Street, London, 18th July, 1839. SIR.-I beg you will present my best respects to the Asiatic Society of Calcutta, and express to them how much I feel honored by the distinction they have conferred upon me in making me an honorary member of their Society. I am happy that any
little service rendered here on my part has been useful to a Society that has been equalled by few, and surpassed by no other, in the spirit and result of its labors. The names of JONES, COLEBROOKE, Wilson, and though last, certainly not the least, that of Mr. James PRINSEP, (whose melancholy state of health every lover of literature, science, and generous disinterestedness must deplore) will ever form a proud subject of remembrance to the Asiatic Society of Calcutta; and make the republic of letters join in the wish of its founder-Esto perpetua.
I need scarcely add, that my humble services will always be at the bidding of the Society
I have the honor to be, Sir,

Royal Geographical Society, London, Ist August, 1839. Sir, I have the honor to acquaint you, that in accordance with the suggestion of Major T. B.

In making this communication, the Council beg to express their hope that this Journal may prove useful to officers who may be about to undertake journeys in the various parts of India, and in the adjacent countries, and to make known to them, that there exists in London a Society specially devoted to the advancement of Geography, which will gladly receive, and publish in the best form, the correct account of any journey in a country of which our Geographical information may be imperfect, as is the case throughout almost the whole continent of Asia.
I am desired to propose to you the exchange, in future, of the Geographical Jourual for the admirable Journal of the Asiatic Society of Bengal, which contains so mueb
valuable Geographical, as well as other information. Should this arrangement meet your views, the subsequent numbers of our Journal shall be dispatched to Calcutta as soon as published.

Your obedient servant,
