Lord Kelvin, who is paying a visit to America, has
been received in New York with the respect due to his character and his scientific attainments. In a speech which he made on the 22nd inst. at a reception given him by the leading scientific bodies he indicated clearly his belief that wireless telegraphy across the oceans would shortly be a success, and that there would be an immense increase in the power of transmitting electrical energy. This is remarkable testimony from a man who does not dream, and to whose knowledge of his subject even Mr. Edison bows. We note, however, with regret that while the great electricians all speak hopefully of the trans- mission of power, they are much more reserved about the great need of the hour, better means for its accumulation. If we could but store energy in some way not involving excessive weight, all means of transit would be rapidly improved, and steam would speedily come to be regarded as an antiquated motive power. The discovery will come, for hundreds of the keenest minds in the world are engaged in the research ; but meanwhile the progress of locomotion halts. With a cheap and light accumulator the world will be a very small place, and will soon contain but few obscure corners.
