the current year, just when the arrangements were completed 
over a great portion of the world, and the fruits were beginning 
to be gathered in. Accordingly, application was made by the 
President and Council of the Royal Society, for their continua- 
tion for another period of three years, to terminate in 1845; and 
at the same time it was officially stated on the part of the Rus- 
sian government, that the observatories in that empire should be 
kept up as long as the British ones, Baron Brunow stating, that 
this extension was the shortest term adequate to obtain results to 
repay the outlay. The British government gave an unhesitating 
assent to the continuation of the present scheme for three addi- 
tional years. For this new potion the peat had been an excellent 
preparation ; all imp tex ggest would 
be adopted; the correction for the temaparasute of the magnets, 
which is found to be the most important of all, will have been 
determined. But the past had not been merely a season of pre- 
paration ; it had afforded demonstrations of the ubiquity of those 
singular disturbances called magnetic storms, which could not 
otherwise have been obtained, and also data for the revision of 
the Gaussian theory. As to magnetic surveys ;—in South Afti- 
cea, Lieut. Clark, R. A. had joined the observatory at. the Cape, 
as assistant to Capt. Wilmot; and it was proposed that the survey 
should comprehend, in addition to the colony, as extended a por- 
tion of the earth’s surface, from the observatory, as circumstances 
would permit. The Admiralty had instructed the Admiral on 
the station to permit the sea portion of the survey to be carried 
into execution, so far as it was not prejudicial to the service, in 
her Majesty’s vessels, and these surveys would include the coast 
on each side of the Cape, and then we should be better able to 
judge of the expediency of completing the survey by an expedi- 
tion into the interior. In North America, Lieut. Lefroy, R. A- 
had been appointed to the principal observatory at Toronto, and 
was now in England preparing instruments. The Hudson’s Bay 
Co. had liberally undertaken to furnish conveyances in the years 
1843—4 and 1845, to extend the surveys to the Pacific Ocean; 
and they also offered passages on board their annual ships to Eng- 
pi this would enable them to include in this magnetic 
vs Bay and Straits. In the United States, Prof.
