TERRESTRIAL MAGNETISM 181 



accomplished in 1845 by Lieut. T. E. L. Moore, R.N., 

 and Lieut. Henry Clerk, R.A., in a vessel hired by 

 the Admiralty for the purpose, and despatched from 

 the Cape of Good Hope. At the meeting of the 

 British Association in 1845, 1 a recommendation was 

 made to the Court of Directors of the East India 

 Company, that a magnetic survey should be made 

 of the Indian Seas in connexion with the magnetic 

 observatory at Singapore. This recommendation 

 was communicated to and concurred in by the Royal 

 Society. The survey, having been entrusted to 

 Captain Elliot, of the Madras Engineers, was com- 

 pleted in 1849. A proposition for a magnetic survey 

 of British India having been submitted to the 

 Association, in a report printed in 1837, a scheme for 

 the execution of such a survey was submitted to the 

 Court of Directors of the East India Company by 

 Captain Elliot on his completion of the survey of the 

 Indian Seas ; and having been referred to the Royal 

 Society, received their warm approbation. The 

 Court of Directors having approved the scheme 

 suggested by Captain Elliot, that officer proceeded 

 to India in 1852 for the purpose of carrying it into 

 execution, but died shortly after his arrival at Madras, 

 in August 1852, having just commenced the opera- 

 tions of the survey. In 1853 a letter was addressed 

 to the President of the Royal Society by the Prussian 

 Minister, Chevalier Bunsen, recommending, by desire 

 of His Majesty the King of Prussia, the Messrs. 

 Schlagintweit, well known by their physical researches 

 in the eastern and western Alps, as fitting successors 

 to Captain Elliot in the magnetic survey of India.
