As was to be expected, the lecture delivered by Mr. Tesla in which he describes the illuminating effects observed in vacuum tubes, has called forth a number of communications from other experimenters...

In The Electrical Engineer of August 12 , I find some remarks of Prof. J. J. Thomson, which appeared originally in the London Electrician and which have a bearing upon some experiments described by me...

(Special Cablegram to The Electrical Engineer.) On the evening of February 3, Mr. Nikola Tesla, by special invitation, delivered a lecture on the results of his latest investigations before the London...

Those who had the good fortune to attend Mr. Tesla's famous lecture at Columbia College last May, will probably have evinced no surprise on reading the account of his lecture delivered in London, as...

Anyone who, like myself, has had the pleasure of witnessing the beautiful demonstrations with vibrating diaphragms which Prof. Bjerknes, exhibited in person at the Paris Exposition in 1880, must have...

If a delicately and pivoted and well-balanced metal disc or cylinder be placed in a proper plating solution midway between the anode and cathode, one half of the disc becomes electro positive and the...

About a year and a half ago while engaged in the study of alternate currents of short period, it occurred to me that such currents could be obtained by rotating charged surfaces in close proximity to...

Sir — In your issue of March 6 I find the passage: "Mr. Kapp described the position as it exists. He showed how Ferraris first of all pointed out the right way to get an alternating-current motor that...

I cannot pass without comment the note of Prof. Thomson in your issue of April 1, although I dislike very much to engage in a prolonged controversy. I would gladly let Prof. Thomson have the last word...

In The Electrical Engineer issue of 11th inst., I find a note of Prof. Elihu Thomson relating to some of my experiments with alternating currents of very high frequency. Prof. Thomson calls the...
