Abstract
Wiedemann's Annalen der Physik und Chemie, No 10.—Gravitational constant and mean density of the earth, by F. Richarz and O. Krigar-Menzel. The gravitational constant, i.e. the constant which has to be inserted in the equation for determining the attraction from the product of the masses and the inverse square of their distance apart, when C.G.S. units are chosen, was found by the method of weighing a mass at two different altitudes above the earth's surface. The result arrived at was 6˙685 x 10-8. The value for the mean density of the earth was 5˙505 ±0˙009.—Surface tension in narrow capillary tubes, by P. Volkmann. When measurements are made on freshly drawn capillary tubes, the results are well in accordance with the known laws, whatever the substance and diameter of the tubes.
