The Council of the Copenhagen University, to whom Dr. Cook sent certain documents for examination, have decided that from the material supplied no proof can be adduced that he reached the North Pole. As Dr. Cook’s instruments and most of his astronomical observations were left behind at Etah, and are still there in consequence of Peary’s refusal to allow them on his ship, it is impossible at present to pronounce a final judgment.=]= Dr. Frederick A. Cook first took part in Arctic exploration as surgeon and ethnologist to Peary’s expedition of 1891. He was then twenty-six years of age. Before the expedition reached Greenland his services were required in a critical emergency. Peary received a fracture of both bones of his leg, and it was to Dr. Cook’s skill that he owed a rapid and successful recovery. Dr. Cook was one of the party on the ice-cap as far as Humboldt Glacier, and when Peary asked for a volunteer to accompany him to the farthest north, Dr. Cook was the first to offer his services. Peary decided to take Astrup, probably because he wished Dr. Cook to take charge of the base camp where Mrs. Peary and the remainder of the expedition had to wait anxiously till his return. Peary states that “to Dr. Cook’s care may be attributed the almost complete exemption of the party from even the mildest indisposition, and personally I owe much to his professional skill, and unruffled patience and coolness in an emergency. In addition to his work in his special ethnological field, in which he has obtained a large mass of most valuable material concerning a practically unstudied tribe, he was always helpful and an indefatigable worker.” After his return from the Arctic, Dr. Cook had a great ambition to try the Antarctic, but did not obtain an opportunity till 1897, and he then had to go on very short notice. The Belgian Expedition had considerable trouble and some disappointment in connection with the surgeons appointed. The first candidate was put aside, after acceptance, for personal reasons, and the second declined to go at the last moment for family reasons. Without a knowledge of this difficulty, Dr. Cook cabled to Belgium from America, volunteering his services, though at the time he had not previously written a line, nor was he acquainted with a single individual of the expedition or its representatives. In reply, he received the instruction, “Meet us at Rio, end of September.” He had only a few days to prepare himself and his outfit for a journey which might take one year or several. French was the language spoken on the ship, but Dr. Cook could not speak a word of it. The Commandant, however, could speak English, and all the scientific staff could speak German, with which Dr. Cook was familiar. This expedition, after doing some valuable work, was beset in the ice, and drifted throughout the whole winter. After an absence of fifteen months, it returned to civilisation in the spring of 1899.
