REPORT OF THE VOYAGE. 



procured, and at the acquirement of these articles, the last American Atlantic expeditions') served as 

 a model, while the appliances for collecting of Plankton were copied from those that had been used 

 on the German Plankton-Expedition, and in accordance with the experiences made on this expedition, 

 the only one where these investigations hitherto had been carried out after a regular plan. 



It was left to the Zoological Museum to supply the expedition with spirits, glasses, and 

 other similar articles for preparation and conservation of the collected material. 



The following gentlemen were destined to take part in the expedition: Commander A. F. M. 

 Evtrs, Lieutenants H. F. Kia-r and H. O. Ravn, Mr. A. C. Otzen as chief engineer, Mr. W. Thnhtrup 

 as surgeon, and the following naturalists: Mr. Osten/eid- Hansen as botanist, Mr. M. Knudsen M. A, as 

 physicist, Mr. H. Hansen. D. P. and Mr. Hector Jungersen, D. P., as well as Mr. W. Lundbeck M. A., as 

 zoologists. 



According to the instructions I received as Cpt. of the cruiser Ingolf^ and by which it was 

 specially pointed out that the principal object of the expedition was to be zoological work and col- 

 lections, the following were the objects the expedition had to carry out: 



1. Soundings with determination of temperature, collecting of samples of water and bottom, 

 determination of the rate and direction of the current at the surface and, if possible, in the depths. 



2. Zoological work. Collecting of marine animals, and preliminary examinations, preparation 

 and conservation of same. The collection was not only intended to comprise what was living on and 

 at the bottom of the sea, but also what could be found in intermediate depths and at the surface, for 

 which purpose the expedition had been furnished with suitable apparatuses. 



3. Botanical work. Collecting of specimens of the vegetable kingdom, and preparation 

 and conservation of these articles for further examination. 



4. Exploring of Fjords. Stays in the Icelandic fjords should be used for examination 

 and surveying of these latter with special regard to the condition of the bottom. (Flora & Fauna). 

 The same applies to the Greenland fjords, provided there be any occasion to visit these latter. 



5. Investigations regarding Fishing. Collection of all data — specially at Iceland — 

 concerning fishing, soundings and collection of bottom material in the shallow sea around Iceland to 

 as large an extent as circumstances would permit. 



6. Meteorological observations. Barometer and thermometer observations, likewise 

 observations concerning the direction and force of the wind, amount of clouds, precipitation, etc., 

 determination of the temperature and specific gravity of the sea at the surface, the presence 

 of ice, etc. 



7. Magnetic observations. Determination of the variation on shore, when the local 

 circumstances would permit this, as well as at sea. 



8. Occasional observations to which circumstances might give rise, such as hydro- 

 graphical work, observations of the ice, sailing directions as well as collections on shore.
