The whole crew of the _Belgica_, without exception, presented symptoms which in medical books are grouped under the name of chronic anæmia. With them all we could notice a discoloration of the mucous membranes, dyspnœa, acceleration of the pulse, dizziness, insomnia, a complete incapacity for prolonged intellectual work, and even a swelling of the legs. The report of the surgeon of the expedition promises to be interesting under this head. I have spoken only to call attention to the studies which were made by the members of the expedition in Patagonia and Tierra del Fuego. They will bring out some zoological, botanical, geological, and anthropological contributions for the knowledge of these important regions of the globe. APPENDIX NO. II THE ANTARCTIC CLIMATE BY HENRYK ARCTOWSKI The following is a preliminary account of some of the additions to our knowledge of the meteorology of higher southern latitudes contributed by the recent Belgian Antarctic Expedition. These desolate antarctic regions, still so little explored, present many physical problems of the highest interest; the question of their climate, attacked as early as the time of Croll, must prove a subject of exhaustive investigation in the immediate future. The results I have obtained were not originally intended for publication in their present form, because the mean values involved can only be regarded as first approximations; however, it appears that my provisional numbers are sufficiently exact to indicate the general nature of the climatic régime in parts of the globe about which we have been, up to the present, practically without information. The fact that other antarctic expeditions are about to set out has decided me to publish my figures as they stand.
