Now, on the electrical view of chemical combination, a univalent atom has one unit charge, if we take as our unit of charge the charge on the corpuscle ; the atom is therefore the beginning or end...

The following experiments, upon which work has been in progress for the past two and one-half years, and their discussion are in line with this assumption, and, as will be seen by the description of the apparatus, ingenious devises, used here in more or less modified...

One of the objects of the present paper is to show that, in case the material is to be used in the notched condition, the usual tests are unable to differentiate clearly between materials that will...

The upper ball was mounted on a spindle so that it could be turned to a freshly polished place without changing its position. The lower one was put in a cup, which in turn was fitted into the frame by means of threads of millimeter or half millimeter pitch, depending on the diameter of the cup. This cup also contains the oil or other dielectric...

There is fairly good agreement among the values found for the specific inductive capacity of water, except those by Drude,4 in the determination of which he used about the same wave-length as that used in the following experiments, and those by Lampa ' for wave-lengths of 4, 6, and 8 mm. In both of these cases the...
