a battery cell made from a ladys silver thimble not to be outdone out done the american operator made a battery from an empty gun cap and a tiny strip of zinc and with this transmitted faint but intelligible signals from hearts content the gun cap battery according to the electrical world is now in possession of mr 11 H ward of new york an observer having noted a large iron steamer which on a temporary gridiron between absolute dryness and parow partial flotation was deflected eight inches a correspondent of engineering delares that the vessel must have been badly strained in experiments on the clyde large steel steamers under varying loads have shown no deflection equal to one inch in their entire length rosin melted with six or eight parts of lard is recommended by prof olmstead as the best protection tor for iron or steel instruments our theories of certain perplexing phenomena are likely to be considerably modified bv the researches prof goldstein is carrying the royal astronomical observatory at B berlin rutn A fact well known is that when a solid body is interposed in the path of the cathode rays in a vacuum tube it becomes itself a secondary source of cathode rays upon which the primary cathode appears to exercise a repulsive action and this has suggested the theory that the sun is a primary cathode sending out cathode rays to immense distances and that the solid or gaseous nucleus of a comet is a secondary cathode which sends out cathode rays always directed away from the sun the secondary rays are the visible tall of the comet in the remarkable experiments already made prof goldstein has reproduced in his vacuum tubes most of the phenomena of comets tails while he hopes to be able to explain such other mysteries as to the red flames and seen around the eclipsed sun with the magnetic thunderstorms and other terrestrial phenomena supposed to be influenced by solar action rubber tubing is used as a core for casting pipes tor for underground service in the novel method of a french engineer the trench is dug and given a bottom of cement mortar then the tubing covered with canvass and inflated is placed on this bottom and the trench is
