Som nævnt i min Afhandling om
Nordhavs-Expedi-tionens Oprindelse og Rejser blev det, da Expeditionen
Iværksættelse var besluttet, overdraget mig at anskaffe de
til Udførelse af de forskjellige Slags Iagttagelser og andre
Arbejder nødvendige Apparater. Under min Rejse til
England i 1875 anskaffedes saaledes flere Apparater og
Instrumenter efter cle fra tidligere Expeditioner anerkjendte
Modeller. I Løbet af Vinteren 1875—76 udførtes de
øvrige Apparater og andre Sager ved norske Verksteder efter
de af mig opgivne Tegninger og Betingelser, ligesom jeg
organiserede og jevnlig udførte Apparaternes Anvendelse
ombord.
Til Grund for den følgende Afhandling, hvis Indhold
er angivet ovenfor, er lagt de udførlige Rapporter om Ap-
Den norske Nordhavsexpeditiou. C. Wille: Apparaterne og deres Brug.
The Government having resolved to despatch a Scientific
Expedition to the Northern Seas. I undertook, as already
stated in my account of the origin and cruises of the
Norwegian North-Atlantic Expedition, at the instance of the
Directors of the Geographical Survey, to procure the various
instruments and appliances wherewith it would have to be
furnished. Several of these, tested and approved by the
experience of former Expeditions. I had constructed in
England, from models, when visiting that country in 1875.
The remaining apparatus, together with all minor
implements requisite for the equipment of the vessel, were made
at Norwegian workshops, in the winter of 1875. myself
furnishing the designs, and stipulating the conditions on
which the work was supplied. Moreover, on the captain
devolved the duty of placing and arranging the apparatus,
and, as a general rule, of superintending their use on board.
This descriptive exposition, the contents of which have
been given above, is in the main an abstract of the special
