Abstract
THE Archives des Sciences Physiques et Naturelles for December 15, contains a paper by Professor Heer, on the Miocene Flora of Spitzbergen. The writer gives a preliminary account of the fossil plants collected and sent to him by the Swedish Polar Expedition of 1868. The number of species found in the Spitzbergen Archipelago amounted to 131, of which 123 were phanerogamic, and 8 cryptogamic. Figures and a detailed description of these are promised to appear in the Memoirs of the Stockholm Academy. The next paper is an extract of Thomsen's Thermo-cheraical Researches (taken from Poggendorff's Annalen), to which Marignac has appended some valuable comments. Prof. Maiignac adds a paper of his own, on the influence of water on the double decompositions of salts, and on the thermal phenomena which accompany them. The author was induced to publish this preliminary memoir in consequence of the appearance of Thomsen's results. He points out some interesting cases of retardation of chemical equilibrium, and intends to investigate them further. The rest of this number—the last of the year— is occupied by the usual Bulletin Scienlifique, Meteorological Observations, and an index to the volume (xxxvi. N. S.}
