sen, Tornoe og Sehmelek, som udførte dem. Endvidere 
skylder jeg min Tak til Hrr. A. S. Steen og N. Oftedal, 
som have assisteret mig med Beregningerne, der have 
været meget vidtløftigere, end det af min Afhandling kan 
sees, idet de simplificerede Methoder først efterhaanden 
bleve fundne. 
De større Dybsø-Expeditioner, som flere af Europas 
og Amerikas større Stater 1 de senere Aar have udsendt, 
ville give et Materiale til Beregningen af Strømningerne i de 
store Verdenshave, som i mange Stykker er bedre end det, 
jeg har havt for Studiet af vort Nordhav. Jeg skulde meget 
ønske, at Nogen vilde forsøge et saadant Arbejde, og at 
min Afhandling kunde være til Vejledning derved. Andre 
Pligter ville ikke tillade mig, som Meteorolog, at paatage 
mig et saa vidtloftigt Arbejde. 
De Ideer, min Methode har givet mig om Vandets 
vil jeg afholde mig fra at frem- 
den Tro, at ikke Raisonnements 
gjennemførte Beregninger kan fore 
Bevægelse i Oceanerne, 
sætte her, da jeg har 
eller Overslag, men kun 
til et blivende Resultat.

and the chemists to the Expedition, Mr. Svendsen, Mr. 
Tornøe, and Mr. Schmelck, by whom it was performed. 
Furthermore, I am indebted to Mr. A. S. Steen and Mr. 
N. Oftedal, who have given me their assistance in working 
out the computations, many of which were exceedingly 
complicated, far more so than will appear from my Me- 
moir, the simplified methods having been found only from 
time to time, as the work proceeded. 
The great deep-sea Expeditions despatched of late 
years by several of the chief nations of Europe and America, 
will yield material for investigating the currents in the 
great oceans of the world, better in many respects than 
what I have had at my disposal for the study of the 
North Ocean. I very much wish that some one would 
undertake a work of the kind, and that my Memoir might 
serve to guide his researches. Other duties, viz., those 
devolving on a meteorologist, will not admit of my at- 
tempting a work so extensive. 
The ideas my 
motion of the water 
method has suggested concerning the 
in the different oceans, I shall refrain 
from communicating here, believing as I do that neither 
argument nor estimate, but carefully worked out compu- 
tations alone, can lead to a lasting result.
