expect to obtain an approximation even of the apparent time, by 

 observation, and he will have no stars to assist him. All his ideas 

 respecting the heavens, and the reckoning of his time, will be 

 reversed, and the change not gradual, as in proceeding from the 

 east to the west, or the contrary, but instantaneous. The mag- 

 netic needle will point to its unknown magnetic Pole, or fly round 

 from the point of the bowl from which it is suspended, and that ' 

 which indicated north will now be south ; the east will become 

 the west, and the hour of noon will be that of midnight." — The

AFRICAN EXPEDITION. 



A letter from Sierra Leone mentions the return to that place 

 of the scientific expedition for exploring the interior of Africa. 

 They were completely unsuccessful, having advanced only about 

 150 miles into the interior, from Rio Nunez. Their progress 

 was there stopped by a chief of the country; and after unavailing 

 endeavours, for the space of four months, to obtain liberty to 

 proceed, they abandoned the enterprise, and returned. Nearly all 

 the animals perished. Several officers died, and, what is remark- 

 able, but one private, besides one drowned, of about 200. Capt. 

 Campbell died two days after their return to Rio Nunez, and 

 was buried, with another officer, in the same spot where IMajor 

 Peddie and one of his officers were buried on their edvauce. 



RUSSIAN VOYAGE OF DISCOVERY. 



Captain Krusenstern in a letter to Captain Burney*, dated 

 Revel, Oct. 1, ISl/, informs him that letters had been received 

 a few davs before from Lieut. Kotzebue. On leaviiig Kams- 

 chatka in July 1S16, he sailed through Behring's Straits, [and 

 succeeded in ranging the coast of America to latitude 67", when 

 he discovered a large inlet extending far to the eastward. He 

 was o])liged to quit it without exploring the whole, but intends 

 to resume the labour this year. Captain Krusenstern dots not 

 him«elf believe that a communication exists between the North 

 Pacific and the Atlantic, but remarks that the discovery of this 

 inlec does hold out some hope that one may be yet found. 



NEW NAUTICAL INSTRUMENT. 



" Mr. Hunter, of Edinburgh, has invented an instrument 

 which is of great importance to the navigator. From two alti- 

 tudes of the sun, and the interval of time between the observa- 

 tions, he can determine, within five minutes after the second ob- 

 servation, the latitude of the place, the hour from noon, and the 

 variation of the compass. According to the common form of
