He never applied for a patent on the instrument, but dedicated it to the public. The device was primarily intended for use in detecting and measuring infinitesimal degrees of temperature, however remote, and its conception followed Edison's researches on the carbon telephone transmitter.
Edison's inexhaustible resourcefulness and fertility of ideas have contributed largely to his great success, and have ever been a cause of amazement to those around him. Frequently, when it would seem to others that the extreme end of an apparently blind alley had been reached, and that it was impossible to proceed further, he has shown that there were several ways out of it.
The article then treats of Edison's investigations into means for supporting and making electrical connection with the active materials, showing some of the difficulties encountered and the various discoveries made in developing the perfected cell, after which the writer continues his description of the "A" type cell, as follows: "It will be seen at once that the construction of the two kinds of plate is radically different.
A germ hates light, preferring to do his scoundrelly work when it is so black that you can't see your hand in front of your face and the darkness presses down on you like a blanket. Occasionally a fear would cross his mind that the night-light might go out; but it never did, being one of Mr. Edison's best electric efforts neatly draped with black veiling.
The Portland cement business has already been dealt with separately, and although the above remarks are appropriate to it also, Edison being its head and informing spirit, the following pages are intended to be devoted to those industries that are grouped around the laboratory at Orange, and that may be taken as typical of Edison's methods on the manufacturing side.
It would carry me into technical details that would hardly interest the reader to describe the mechanism of Mr. Edison's flying machine. Let it suffice to say that it depended upon the principal of electrical attraction and repulsion.
It is hard to determine where to begin with Edison's miscellaneous inventions, but perhaps telegraphy has the "right of line," and Edison's work in that field puts him abreast of the latest wireless developments that fill the world with wonder.
This great and notable plant, representing a very large outlay of money, brought to completion, ready for business, and embracing some of the most brilliant and remarkable of Edison's inventions and methods, must be abandoned by force of circumstances over which he had no control, and with it must die the high hopes that his progressive, conquering march to success had legitimately engendered.
The staff made over fifty thousand experiments in all for this one purpose. This illustrates the art and necessity of taking pains, one of Mr. Edison's greatest characteristics. The story of producing electric light would fill a big volume. "When the proper filament was discovered and applied there was great rejoicing in the laboratory and a regular orgy of playing pranks and fun.
When bringing it in proper contact with this wonderful instrument, she hears her consort's voice, just as if he was by her side, and a thousand leagues were but a few inches. Moreover, Edison's kimetograph portrays the beloved features of her absent spouse. She is now perfectly consoled; for the radiant expression of his countenance manifests health and happiness.
