I HAVE the honour to acquaint you with the arrival of 

 Her Majesty's ship under my command, and the Terror, 

 under my orders, this afternoon at this port. 



I have further to report to you, for the information of my 

 Lords Commissioners of the Admiralty, that in accordance 

 with the intentions expressed in my despatch to you, dated 

 from HobartTown on the 11th of November last, 1 proceeded 

 to Auckland Islands, and satisfactorily accomplished a com- 

 plete series of magnetometric observations on the important 

 term-day of November last. 



Under all the circumstances, it appeared to me, that it would 

 conduce more to the advancement of that branch of science 

 for which the expedition has been more expressly sent forth, 

 as well as for the extension of our geographical knowledge of 

 the Antarctic regions, to endeavour to penetrate to the south- 

 ward, or about the 1 70th degree of east longitude, by which the 

 isodynamic oval, and the point exactly between the two foci
