[Copy. 



U. S. Ship Peacock, 



Sydney, New South Wales, 

 March 3d, 1840. 



Sir, — - 



I have the honour to report the arrival of the Peacock at this port, 

 for the purpose of making such few repairs as have become necessary, 

 preparatory to the further prosecution of the objects of the Expedition, 

 and avail myself of the occasion to say, that in our recent adventures 

 south, we fell in with a barrier of ice in the latitude of 65° S., and 

 longitude 159° E., and had followed its trendings as far as 67° S., 

 longitude 150° E.
