There appears to be no abatement in expeditions for polar discovery and adventure. Lieutenant Peary remains in the far north, seeking to reach a point nearer to the Pole than did Dr. Nansen and the Duke of Abruzzi's party, while with the same object in view Mr. Baldwin is preparing an expedition, liberally equipped by Mr. Ziegler, of New York City, and Captain Bernier is making efforts to secure a similar outfit in Canada. These expeditions are perhaps not primarily for scientific research, though they should add to knowledge in many directions. The expeditions being fitted out with the assistance of the German and British Governments for antarctic exploration are, however, strictly scientific in character. Exploration in the north has never relaxed, but since Sir James Ross returned, in 1843, efforts to explore the south polar region have been sporadic and comparatively unimportant, until the recent expeditions under Captain de Gerlache and Mr. Borchgrevink. The scientific results of these expeditions have not yet been published, though descriptive volumes by Mr. Borchgrevink and Dr. Cook have recently been issued, and the latter has contributed to the present number of this Journal an interesting account of the unknown southern aurora. The 'Belgica,' from which Dr. Cook made his observations, was not, however, altogether fortunate in its course, and possibly the dramatic interest of the first antarctic night is greater than the scientific interest of the results. Mr. Borchgrevink followed pretty closely in the track of Sir James Ross, and his own book contributes little or nothing to scientific knowledge. He reached by a day's expedition a point furthest to the south, but it is not even obvious how he determined this, when he estimates the semi-diameter of the sun as 16° 17' 1". However valuable the scientific results of the voyages of the 'Belgica' and of the 'Southern Cross' may prove when published, there is certainly room for the great expeditions now being made ready in England and in Germany.
