vention for two years, and he now promises to work wonders in the mechanical world. Dr. Bryan’s battery is wholly different from anything of the kind heretofore man- ufactured. Not yet being protected by patents he will not tell what his secret is, except in a general way. A combination of chemicals, altogether new, is made, and their action is so slow, yet strong, that the current generated will last with constant use, from estimates now made, from three to five years. An ordinary battery is good only for twelve hours. The inventor throws a little light on his secret by saying that a reversal of the current causes a reoxidization of the chemicals, thus strengthening the battery. To Guard Against the Baggage Smasher. The Bradbury-Stone Storage Battery Co., of Lowell, Mass., are constantly de- vising means to guard again>t the careless- ness of express companies who are the bete noire of the storage battery business. Mr. J. S. Stone, Secretary of this.com- pany, called recently to see us and in reference to this subject said, “It is abso- lutely necessary that a battery should be ironclad, so to speak.” He had with him a small cell, which he showed a Phonogram reporter, that seemed to answer every requisite. The battery is imbedded in a rubber cushion, has strong flexible acid proof lugs, insulated from the cover. It is set up in a handsomely finished hardwood cabinet, dovetailed and glued. A hard rubber tubing one and,one- quarter inch in diameter with a threaded cover or cap to screw on, prevents spilling of the acid and exposes the interior of the cell so that the depth of the acid solution can be obtained by simply removing the cover. Nothing could be more convenient and durable. The efficiency of the battery remains unquestioned. The Bradbury-Stoue Co. are filling a large number of oYders for these improved cells. This metal is beginning to receive from manufacturers, architects and artisans of every class the recognition to which its merits entitle it. The description of a boat constructed of aluminium appeared in a former issue of The Phonogram, and it is a well-known agent of the dec- orative m ployed. m various handicrafts and has been the subject of elaborate investigation by Mr. Holland, who presented the result of his researches to the Academy of Sciences at Paris, He found that with regard to its corrodibility, it is not so easily attacked as iron, copper, lead, tin or zinc, byair, wine, water, beer, coffee, milk, oil, butter, gas, saliva, etc. Vinegar-and salt attack it, but not to such an extenfaas renders its use undesir- able fo r r domestic cooking utensils and similar purposes. The Germans condemn it for” these uses, but the French do not sustain their opinion. In the United "States, a ty^writer has very recently been manufactured entirely of aluminium that Weighs 6 d4v-4oIi pounds and offers excel- lent resistance to the strain to which con- tinual use subjects all machinery.
