Abstract
No. 3 of the Bulletin de I'Academie Impérials des Sciences de St. Petersburg, t. xvii., contains seven anatomical papers by Dr. Wenzel Grüber—six on various abnormal muscular forms, and the seventh being an account of the formation of supernumerary wrist-bones.—An appreciative paper on Sir Roderick Murchison is communicated by G. Helmensen. He refers to Murchison's visits to Russia between 1840 and 1845 to study the palæozoic formations. In a résumé of results, he mentions, among others, the discovery, in post-pliocene strata in the lower course ot the Dwina, of the shells of species still extant in northern seas; of a Jurassic formation in large zones and fields between the Volga and the Timan Hills, at the western base of the Urals, and m the north-east part of the Caspian lowland; and of two quite d stinct coal beds in Central Russia. The writer considers that the work of our countiyman has been imperfectly followed up these twenty-five years. He speaks in warm terms of Sir Roderick's friendship for the Russians. —In a note by M. Jacobi, it is suggested to apply galvanoplastic art to the production of standards of length, on the principle that electrodes having the same dimensions and position, baths the same composition and temperature, currents the same intensity, the deposits produced in such circumstances ought to be very nearly equal. Details of such a method are fully given.—A lengthy article by Dr. Hilde-brand gives an outline of some 600 historical documents among the archives of the town of Revel, which throw considerable light on the commercial relations of Russia and Livonia in the fifteenth and sixteenth centuries.—The number contains, in addition, two short notes on Faye's comet and the Fossil Cetacea of Europe.
