PREFACE TO VOL. I. 
Te 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. Sigurp Scott-Hansen. In my preface to Vol. I of this

able to accomplish, and to the intelligent care and accuracy with which he 
made them, notwithstanding the often trying circumstances. 
Memoir VI, containing the Astronomical Observations made during the 
expedition, and their Results, has been prepared by Prof. H. GEELMUYDEN. 
Before our start, Prof. GeELMUYDEN gave the expedition his important 
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
