It also registers the hour at TMtnnt Vn prvnl I which central is rung up, and any interruption in the conversation. The device consists essentially of a clock and printing apparatus, and will compute the charge at whatever rate it is adjusted for. A most remarkable electrical storm at sea is reported by the British steamship Mercedes, which recently reached New York with a cargo of Spanish iron ore. On the nights of December 3rd and 4th, banks of Newfoundland, the Ion the grand appeared like a mighty mass of flames. Balls of electric fire hissed and exploded in all directions and darted in all directions through the vessels rigls As the huge came toging. gether they would burst with a loud report and disappear. A Jacksonville, Fla., dentist, by means of a spring instrument, has determined the force exerted by the human jaws in chewing food. The smallest pressure was 30 pounds, by a little girl, with the incisors, but with her molars she exerted a force of 65 pounds. Many persons exceeded 100 pounds with the incisors and 200 pounds with the molars. The record was taken by a physician, who registered the full capacity of the instrument, 270 o pounds, without effort. Oreon S. Rhodes, East Stroudsburg, Pa., has invented an appliance for the generation of vapors of volatile liquids and driving motors thereby, the boiler fluid being preferably a fixed oil boiling at a high calcu-lagrap- h. AjTjf-pmnH- fire-bal- temperature, giving great heat without corresponding pressure, and the vapor being generated from a volatile liquid combined with a soluble gas, a volatile liquid, or a liquefied gas. The boiler and engine form but one machine, both making use of the same boiler fluid, the construction being such that the fuel is utilized to the greatest advantage and the danger from explosion is reduced to a minimum.

The syndicate of Chicago capitalists who purchased the pumice deposits in southern Utah last year have expended much money In erecting buildings and machinery and placing the property in shape for production. The output will be twenty tons per day, and eight different grades of powdorod pumice will be produced. The product is shipped to Pennsylvania. 1 jjiywi vm V ! I J. |
