394 Intelligence and Miscellaneous Articles, 



I some time ago made a few experiments on this point j but I have 

 not yet had time to prosecute them far enough to obtain a sufficient 

 number of accurate results to form just notions as to the probable ex- 

 tent to which this mode of analysis may be carried. 



With regard to copper and zinc, the law appears to hold good 

 when the battery is not too powerful. I have employed 100 pairs of 

 one-inch plates, and also 100 of two-inch plates, and have obtained 

 the same results. The metals were held in solution by sulphuric acid 

 and water. Whilst the battery was active, both copper and zinc were 

 deposited on the negative platina wire ; but when the power was less 

 active, the copper alone was revived. 



I throw out these hints in order that others, better circumstanced 

 than I am, may, if they please, take advantage of them The field, I 

 believe, is quite new, and appears to me to be worthy of investigation.

RETURN OF THE EXPEDITION UNDER CAPTAIN ROSS. 



[Feeling desirous of recording in our pages, in an authentic form, 

 the happy return of Captain Ross and his brave associates, from 

 their perilous undertaking, we insert his official letter on the sub- 

 ject to the Secretary of the Admiralty. An obliging communi- 

 cation with which we have been favoured by Captain Ross, in- 

 duces us to hope that we may be able to make public some ad- 

 ditional particulars in our next. — Edit.]

* On board the Isabella, of Hull, Baffin's Bay, Sept. 1833. 



" Sir, — Knowing how deeply my Lords Commissioners of the Ad- 

 miralty are interested in the advancement of nautical knowledge, and 

 particularly in the improvement of geography, I have to acquaint you, 

 for the information of their Lordships, that the expedition, the main 

 object of which is to solve, if possible, the question of a north-west 

 passage from the Atlantic to the Pacific Ocean, particularly by Prince 

 Regent's Inlet, and which sailed from England in May 1 829, not- 

 withstanding the loss of the foremast and other untoward circum- 

 stances, which obliged the vessel to refit in Greenland, reached the 

 beach on which His Majesty's late ship Fury's stores were landed., on 

 the 13th of August. 



"We found the boats, provisions, &c, in excellent condition, but no 

 vestige of the wreck. After completing in fuel and other necessaries, 

 we sailed on the 14th, and on the following morning rounded Cape 

 Garry, where our new discoveries commenced, and, keeping the west- 

 ern shore close on board, ran down the coast in a S.W. and W. course, 

 in from ten to twenty fathoms, until we had passed the latitude of 

 72° north in longitude 94° west : here we found a considerable inlet 

 leading to the westward, the examination of which occupied two daysj 

 at this place we were first seriously obstructed by ice, which was now 

 seen to extend from the south cape of the inlet, in a solid mass, 

 round by S. and E. to E.N.E. : owing to this circumstance, the 

 shallowness of the water, the rapidity of the tides, the tempestuous
