As I shall have frequent occasion later on to speak of other details of our equipment, I shall content myself here with mentioning a few of the most important. Special attention was, of course, devoted to our commissariat with a view to obviating the danger of scurvy and other ailments. The principle on which I acted in the choice of provisions was to combine variety with wholesomeness. Every single article of food was chemically analyzed before being adopted, and great care was taken that it should be properly packed. Such articles, even, as bread, dried vegetables, etc., etc., were soldered down in tins as a protection against damp. A good library was of great importance to an expedition like ours, and thanks to publishers and friends, both in our own and in other countries, we were very well supplied in this respect. The instruments for taking scientific observations of course formed an important part of our equipment, and special care was bestowed upon them. In addition to the collection of instruments I had used on my Greenland expedition, a great many new ones were provided, and no pains were spared to get them as good and complete as possible. For meteorological observations, in addition to the ordinary thermometers, barometers, aneroids, psychrometers, hygrometers, anemometers, etc., etc., self-registering instruments were also taken. Of special importance were a self-registering aneroid barometer (barograph) and a pair of self-registering thermometers (thermographs). For astronomical observations we had a large theodolite and two smaller ones, intended for use on sledge expeditions, together with several sextants of different sizes. We had, moreover, four ship's chronometers and several pocket-chronometers. For magnetic observations, for taking the declination, inclination, and intensity (both horizontal and total intensity) we had a complete set of instruments. Among others may be mentioned a spectroscope especially adapted for the northern lights, an electroscope for determining the amount of electricity in the air, photographic apparatuses, of which we had seven, large and small, and a photographometer for making charts. I considered a pendulum apparatus with its adjuncts to be of special importance to enable us to make pendulum experiments in the far north. To do this, however, land was necessary, and, as we did not find any, this instrument unfortunately did not come into use. For hydrographic observations we took a full equipment of water-samplers, deep-water thermometers, etc. To ascertain the saltness of the water, we had, in addition to the ordinary areometers, an electric apparatus specially constructed by Mr. Thornöe. Altogether, our scientific equipment was especially excellent, thanks in great measure to the obliging assistance rendered me by many men of science. I would take this opportunity of tendering my special thanks to Professor Mohn, who, besides seeing to the meteorological instruments, helped me in
