There is at present no one disabled, but there are many little complaints. About half of the men complain of headaches and insomnia; many are dizzy and uncomfortable about the head, and others are sleepy at all times, though they sleep nine hours. All of the secretions are reduced, from which it follows that digestion is difficult. Acid dyspepsia and frequent gastric discomforts are often mentioned. There are also rheumatic and neuralgic pains, muscular twitchings, and an indefinite number of small complaints, but there is but one serious case on hand. This is Danco. He has an old heart lesion, a leak of one of the valves, which has been followed by an enlargement of the heart and a thickening of its walls. In ordinary conditions, when there was no need for an unusual physical or mental strain, and when liberal fresh food and bright sunshine were at hand, he felt no defect. But these conditions are now changed. The hypertrophied muscular tissue is beginning to weaken, and atrophy of the heart is the result, dilating and weakening with a sort of measured step, which, if it continues at the present rate, will prove fatal within a month. May 22.--It is clear and still. The temperature has fallen to -19° C., and altogether, though sunless, this sharp, cold weather at present is more agreeable to us than the dull, stormy days with warmth and light a month ago. It is Sunday, and we have nearly all been out for a jaunt on _skis_. We took some photographs, but they are ugly, because there is nothing distinct in the pictures. It is not possible to make good, clear pictures except on bright moonlight nights or on sharp, sunny days. It is the custom aft to go into the masthead and scan the horizon for signs of life, before starting on our tours of recreation. In this way we are reasonably sure to return with a penguin, a seal, or the story of an adventure. To-day we saw a seal about a mile from the ship, but when we got to it the animal started towards the _Belgica_. We urged it on and drove it easily to our home. The creature looked about with much curiosity when it came to the rough, dirty snow about the bark, and searched diligently for a hole through which it might plunge to the sea below. But no such hole or crevasse was within a mile of us, for the calm cold of the past week has reunited all the broken fragments into large fields. We threw a rope around the seal, which was a crab-eater, intending to take its temperature and make other physiological experiments, but the thing was too slippery and too lively for us. Several instruments were broken, and some very strong ropes were snapped like ordinary twine. Finally the seal was shot, and its skeleton was prepared to enrich a Belgian museum of natural history. There was to-night a bright aurora. It began as a straight horizontal zone low on the southern sky. Later it changed to an arc with the parts of two other arcs below it. A similar phenomenon appeared last night.
