Mr. F. Himstedt publishes in Wiedemann's Annalen, vol. 52, page 473, some interesting researches with Tesla currents, produced by means of rather simple apparatus. We ge below a translation of an...

BY H. M. MARTIN AND W. H. PALMER, JR. All who visited the room in the Electricity Building at the World's Fair in which Mr. Tesla's high frequency apparatus was exhibited must have brought away with...

(Concluded from last issue.) Two patents have been granted in this country which make use of the method of signaling by electrical waves. One is the familiar patent to Marconi, 586,193, July 13, 1897...

Electrostatic Induction Methods The electrostatic system may be said to represent an intermediate stage in the development of the art of telegraphing without line wires. Some of the difficulties which...

Intense interest has of late been aroused in the many striking phenomena connected with oscillatory currents. This interest was first awakened among professional electricians and physicists by the...

At last the much talked of lecture of Mr. Tesla, held in London in February, has reached this side. In order to give Americans the benefit of it, we print it in full in this issue. It forms a very...

It will be seen from the patents hereinafter cited that the present subject is not new. It has occupied the attention of inventors for at least fifty years; and, indeed, if we include signaling by...
