Abstract
Pongendorff's Annalen der Physik und Chemie, Nos. 3 and 4, 1875.—These parts contain the following papers:—Remarks on electro-dynamics, by F. Zoellner. These refer to Ampère's law and Helmholtz's potential law.—On the proportion of temporary magnetism to the magnetising force and its relation to the reciprocal action of the metallic particles, by E. Boernstein.—Remarks on the paper of Dr. Streintz, on the torsion oscillations of wires, by O. E. Meyer.—On the conducting resistance at the points where metallic conductors touch, by F. C. G. Müller.—On the specific heats of the elements carbon, boron, and silicon, by Dr. H. F. Weber; this is the first paper on the subject, and treats on the dependence on temperature of the specific heats of the isolated elements in. question.—On the path of the rays of light in a spectroscope, by Dr. J. L. Hoorweg.—On electrodes which cannot be polarised, by A. Oberbeck.—On the conduction of electricity in electrolytes, by W. Beetz.—Supplement to K. L. Bauer's paper (vol. 153, p. 572, of these Annals) on the apparent position of a point of light situated in a denser medium, by the author.—General theorems on the images of spheric mirrors and lenses, by the same.—On the theory of the process of assimilation in the vegetable kingdom, by E. von Benkovich.—On a simple method of finding the poles of a rod magnet, by F. C. G. Müller.—On the determination of the velocity of light and the parallax of the sun, by A. Corau. This paper is taken from the Comptes Rendus.—On the unipolar conduction of electricity through layers of gases of different conducting capacity, by C. Braun.—New researches on the currents in electric machines, by F. Rosette.—Some remarks on Helmholtz's theory of vowels, by E. van Qvanten.—On the theory of anomalous dispersion, by H. Helmholtz.—On an electric fall machine, by H. Waldner.—On the experimental determination of diamagnetism by its action of induction, by A. Toepler.—On an optical method of studying the oscillation of solids, by O. N. Rood.—On a new kind of variation sounds, by V. Dvorak.—On the spectrum of the zodiacal light, by Arthur W. Wright (from the American Journal of Science).—Some remarks on Thomson's electrometer, by K. A. Holmgren.—Electroscopic note by the editor.
