 turalier, som Expeditionen tilveiebringer, forblive denne

videnskabelige Medlemmer ere bearbejdede. ' Publikationen

 lingen af de indsamlede Naturalier beåtemmes af Bestyrel-

Kor hvert Aars Togt udarbejdedes af Expeditionens 

 Medlemmer i Forbindelse med Opmaalingsdirectionen (Gene- 

 ral Grimsgaard. Fyrdirektør I (iriks 'og Professor Mohn) en 

 Arbéjdsplan. der indsendtes til Departementet for det Indre 

 til Approbation. 



1876. 



Den for (lette Aar approbérede Plan var følgende: 



Saasnart Expeditionsfartojet i Bergen har modtaget 

 sin tidde Udrustning og de Instrumenter og Apparater, 

 der skulle have sin Plads Ombord, ere anbragte, kunne de 

 Iagttagelser begynde, der ere nødvendige for Bestemmelsen 

 af de forskjellige magnetiske Oonstanter ved Skibet og de 

 .respective Instrumenter. 



Da saadaune Iagttagelser hor foretages paa et Sted. 

 der er saavidt muligt 1'rit for den saakaldte magnetiske Lo- 

 calattraction, og da Erfaringen fra "Hansteens" Togt i 

 1875 har vist. at man ikke kan gjøre Regning paa at 

 blive fri for denne Virkning, førend man kommer ud paa 

 de yderste Øer -og Skjåer paa Kysten, ville de nævnté Iagt- 

 tagelser ikke kunne udføres med Fordel i Bergen. 



Af Besultaterue af "Hansteens" Togt i 1875 frem- 

 gaar det. at Øei - ne Utvær., og navnlig Hus<> ved Sogne- 

 fjordens Munding har den foronskede Frihed for Localat- 

 traction. Paa dette Sted ville derfor de forberedende mag- 

 netiske Iagttagelser antagelig hedst blive at udføre. Hvor 

 lang Tid disse Iagttagelser ville tåge. beror paa Vejrfor- 

 holdene, navnlig fordi der til enkelte af dem kræves Sol 

 til en bestemt Dagstid. 



Da en Flerbed al de Instrumenter og Apparater. 

 hvormed Expeditionen vil have at arbejde. paa denne komme 

 til Anvendelse under Forhold, der paa Grund af Fore- 

 tagendets større Maalestok og Udrustningens større Fuld- 

 stændighed ere Expeditionens Deltagere delvis nye. og da 

 Mandskabet fcrænger til Opøvelse i de for de videnskabe- 

 lige Operationer nødvendige Manøvrer, ansees det for mest 

 heiisigtsmæssigt og i Længden mest tidsbesparende at fore- 

 tage foreløbige Forsøg til Øvelse med samtlige de under 

 Expeditionen benyttende Apparater. 



Eu udmerket Lejlighed til den forste Prove, der til- 

 lader l )perationerne at foregaa i smult Vand paa samme 



ended. the memhers of the Scientific Stan' shall send in a 

 Genera] Report ti. the Managing Oommittee. 



§ 6. 

 The observations instituted and natural objects col- 

 lected shall belong to the Expedition till such time as, 

 with the approbation of tin- Scientific Staff, they liave heen 

 duly worked mit and described. Tlie pubbcation of the 

 observations aud their results. and the distribution of the 

 natural objects, to devolve on the Directors of the Geo- 

 graphical Survey, and to be in accordance with the propo- 

 sition of the Scientific Staff. 



For eacli cruise the members of the Scientific Staff, 

 in eonjunction with the Directors of the Geographical Sur- 

 vey (General Grimsgaard. F. Diriks. Director of Light- 

 houses. and Professor Mohni. drew up a Scheme of Work, 

 which was laid before the Home Department for approval. 



1876. 



The .Scheme approved for this year was as follows: — ■ 



When the vessel selected for the Expedition. now 

 lying in the port of Bergen, has been fully equipped, aud 

 the instruments and apparatus with which she is to be 

 furuished have been arranged ou board, the observations 

 necessary to determine the magnetic constants for the ship 

 and the respective instruments niay forthwith commence. 



As such ' observations should be tåken in a spot as 

 nearly as possible free from the so-called magnetic local 

 attraction, and the cruise of the "Hansteen' in 1875 haviug 

 shown that this disturbing inrluence does not cease to be 

 felt at å less distance from the coast than the outermost 

 islands and skerries, the said observations cannot gjve satis- 

 factory results il made in Bergen. 



From observations instituted ou the cruise of the 

 -Hansteen'' in 1875. it appears that the islands of Utvær, 

 and more especially the island of Husø at the entrance 

 to the Sognefjord, are well nigh uninnuenced by local 

 attraction. On the latter island. therefore. it will be best 

 to undertake the preliminary magnetic observations. What 

 time will he required to complete these observations. must 

 depend on the state of the weather. particularly since 

 sunshine at a certain hour of the day is indispensable for 

 some of them. 



As very many of the instruments and appliauces ne- 

 cessary for the Expedition. will have to be used under 

 conditions which. by reason of the comparatively extensive 

 scale whéreon the Expecbtion has been planned, and the 

 relative completeness of eqmpment. are in several respects 

 new to the members of the Expedition: and the crew 

 needing practice for the work connected with the scientific 

 operations. it is deemed advisable. and will in the long run 

 be the surest means of saving time. to make preliminary 

 excursions, or trial-trips. with a view to acquire experience 

 in handling the apparatus. 



An excellent locality to begin with. that would admit 

 of carrying on the operations both in smooth water and
