considerable improvements in the fishing, with a facility and certainty of 
increased revenue, will be the result, and all difference of opinion, doubt, 
and suspense, will be at an end.

Sir: 
I beg leave, in answer to your letter of the 16th of February, to recom- 
mend to the Council that Captain Srevarr’s ‘ Account of the Pearl 
Fisheries on the North-West Coast of the Island of Ceylon,” be printed 
in the Transactions of the Society; and that, in order to enable the public 
to become better acquainted with the relative situation of the Pearl-banks, 
a copy be annexed to it of the map of the gulf of Mandar, framed by Mr. 
Hesert, of the Colonial Office, principally from the materials which I 
presented to that office some time ago, and which I collected while I was 
on the Island of Ceylon, with a view of explaining a report upon the 
fisheries, geology, and natural history of the gulf, which I made to the late 
Marquess of Lonponprrry, the then Secretary of State for the Colonies, 
in 1809, when I submitted to his Lordship a plan for changing the system 
observed by the Ceylon government, in the management of the Pearl 
and Chank* fisheries on the North-West Coast of Ceylon, for placing all 
the Pearl and Chank banks in the gulf of Mandr, as well those belonging 
to the East-India Company as those belonging to the Crown, under one 
and the same management; and for executing without delay a survey of 
the whole of that Gulf by able and scientific men, who could procure on the 
spot for His Majesty’s Government such information relative to the history,
