Should the expedition, contrary to expectation, not succeed in carrying out the programme which has been arranged in its entirety, it ought not to be looked upon as having failed. In such a case the expedition will remain for a considerable time at places on the north coast of Siberia, suitable for scientific research. Every mile beyond the mouth of the Yenisej is a step forward to a complete knowledge of our globe--an object which sometime or other must be attained, and towards which it is a point of honour for every civilised nation to contribute in its proportion. Men of science will have an opportunity, in these hitherto unvisited waters, of answering a number of questions regarding the former and present state of the Polar countries, of which more than one is of sufficient weight and importance to lead to such an expedition as the present. I may be permitted here to refer to only a few of these. If we except that part of the Kara Sea which has been surveyed by the two last Swedish expeditions, we have for the present no knowledge of the vegetable and animal life in the sea which washes the north coast of Siberia. Quite certainly we shall here, in opposition to what has been hitherto supposed, meet with the same abundance of animals and plants as in the sea round Spitzbergen. In the Siberian Polar sea, the animal and vegetable types, so far as we can judge beforehand, exclusively consist of survivals from the glacial period, which next preceded the present, which is not the case in the Polar Sea, where the Gulf Stream distributes its waters, and whither it thus carries types from more southerly regions. But a complete and exact knowledge of which animal types are of glacial, and which of Atlantic origin, is of the greatest importance, not only for zoology and the geography of animals, but also for the geology of Scandinavia, and especially for the knowledge of our loose earthy layers. Few scientific discoveries have so powerfully captivated the interest, both of the learned and unlearned, as that of the colossal remains of elephants, sometimes well preserved, with flesh and hair, in the frozen soil of Siberia. Such discoveries have more than once formed the object of scientific expeditions, and careful researches by eminent men; but there is still much that is enigmatical with respect to a number of circumstances connected with the mammoth period of Siberia, which _perhaps_ was contemporaneous with our glacial period. Specially is our knowledge of the animal and vegetable types, which lived contemporaneously with the mammoth, exceedingly incomplete, although we know that in the northernmost parts of Siberia, which are also most inaccessible from land, there are small hills covered with the bones of the mammoth and other contemporaneous animals, and that there is found everywhere in that region so-called Noah's wood, that is to say, half-petrified or carbonised vegetable remains from several different geological periods.
