Abstract
THE Mittheilungen der naturforschenden Gesellschaftin Bern for 1869, published last year, contain many important papers.—M. E. Schär publishes a valuable contribution to the knowledge of some cyanogen compounds, and a memoir of considerable length on peroxide of hydrogen, and its relations to ferments.—M. A. Gruner communicates a short but interesting paper on the luminosity of the so-called “touchwood,” in which he details several experiments, and comes to the conclusion that ozone is to be regarded as the principal cause of the phenomenon.—In geology we find some valuable memoirs by M. C. von Fischer-Ooster, especially a paper on the Rhætic stage in the neighbourhood of Thun, which includes an account of the beds, and a list of the fossils occurring in them, with descriptions of some new species, and many figures. The same author also contributes several smaller papers on the occurrence of a Liassic zone between the chain of the Moleson and the Miremont in the Canton of Freiberg, on the narrow Flysch zone from the Hongrin towards Jaun, on the geological age of the so-called Tavigliana Sandstone, and on the stratigraphical conditions near the Küblisbad.—M. J. Bachmann publishes some remarks in opposition to M. Renevier's geological observations on the Alps of Central Switzerland compared with the Vaudoise Alps, and M. A. Rytz a notice on the erratic formations in the Kanderthal.—M. Theophil Studer notices the occurrence of Foraminifera in the Alpine chalks, detected by the examination of thin slices, and also describes a new Swiss form of the genus Tropidonotus, for which, however, he does not venture to propose a specific name.—Dr. R. Henzi reports upon the attempts made by him to cultivate Saturnia Mylitta and S. yama maya, and M. G. Hasler describes and figures an apparatus for giving telegraphic intimation of the height of water in reservoirs, &c.—The Proceedings of the society also contain short notices upon various subjects.
