THE KEELY MOTOR.
From the Bulletin, June 28, 1875.

Until we have this practical demonstration any expression of judgments is premature. If Mr. Keely can prove his case he is entitled to his opportunity. Mean while it is not an easy matter to convey an intelligible conception of what the alleged new discovery is, divested of the scientific technicalities. The motive principle is represented to be the expansive power of carbonic acid. This important compound, under a pressure of 36 atmospheres, at temperature of 32 degrees becomes liquid; and when the pressure which retains it in the liquid state is renewed, the rapidity of the evaporation and the enormous expansion of the vapor are such as to preclude a degree of cold under which acid solidifies, forming a white concrete substance possessed of very extraordinary properties. Prof. Faraday was the first who liquefied carbonic acid, but it was first treated as a solid by W. Thilonrier. At common temperature and pressures water absorbs its own volume of carbonic acid; under a pressure of two atmospheres it dissolves twice its volume, and so on. A correspondent of the Savannah News, who has made numerous and expensive experiments, has no doubt of its power as a mechanical agent, and adduces the following progressive augmentation of its expansive properties by increased temperatures:

At 05° Fahrenheit the pressure in pounds per square inch is 372.
At 10° Fahrenheit the pressure in pounds per square inch is 403.
At 20° Fahrenheit the pressure in pounds per square inch is 460.
At 30° Fahrenheit the pressure in pounds per square inch is 560.
At 40° Fahrenheit the pressure in pounds per square inch is 697.
At 45° Fahrenheit the pressure in pounds per square inch is 1,080.

Heretofore the great scientific difficulty has been to know how to utilize this wonderfully expansive power - to put the harness on it, so to speak, and to work it as Prof. Morse has harnessed electricity and compelled it to carry messages. Now, Mr. Keely claims, this difficulty has at length been conquered. The advantage claimed over steam and the steam engine are many, not the least of which are economy, safety, and easy control. If applied to navigation the propelling power, it is said, would not cost more than \$5 to run a steamer from Savannah to New York; and, as the necessary machinery will not take up one-fourth part of the weight and room of the boiler, engine, and fuel of equal power, another advantage would be additional carrying capacity and space for freight.
