Petrovitch: A new method of numerical evaluation of the coefficients of series.—C. Benediks: A new thermo-electric effect. The author's results are contrary to the law of Magnus, and show that in a homogeneous metallic circuit an asymmetrical distribution of temperature may give rise to an electromotive force.—J. B. Tauleigne and G. Mazo: The method of monocular stereoscopy esp ciaiiy applicable to radiography.—M. Mazeres: A new method of extraction with the radioscopic screen: the method of concordances.—D.
