PEEFACE TO VOL. II. 



_Lhe astronomical, magnetic, and pendulum observations affording the 

 material for the three important Memoirs contained in this volume, were nearly 

 all of them, with the exception of the observations from the sledge-journey, 

 made by Capt. SIGURD SCOTT-HANSEN. In my preface to Vol. I of this

 made them, notwithstanding the often trying circumstances. 



Memoir VI, containing the Astronomical Observations made during the

 assistance by aiding in our equipment with astronomical instruments and 

 chronometers, and giving us instruction in the best methods of making 

 observations for determining our position in high latitudes. After our return, 

 he had the great kindness to undertake the troublesome and slow work 

 of arranging and supervising the computation of our numerous observations, 

 and preparing the report for the press. He has also constructed and drawn 

 the two valuable charts accompanying this volume, of the Fram's route and
