Today It has becomo such a common affair that wo seldom pause to think of tlio Improvement, Im-provement, but simply tako It for granted, as wo havo learned to do tho thousand and ono other things which tho Inventor has placed at our disposal. dis-posal. But' eventhis- little glass bulb, with Its raj'8 of HghKjitreamlng out all around, Is opcirfo Improvement. In almost overy use to which this lamp Is put there Is no necessity for the rays which Illuminate the spaco abovo tho carbon Mm, and this Inventor proposes pro-poses not only to shut them out, but to reflect them downward again, whero they will Increase tho brilliancy of the vertical rays. This Is accomplished accom-plished by tho uso of the llttlo metal reflector shown In conjunction with ' tho Incandescent electric light In tho picture.

Tho meteorologist Is gradually dl-' vostlng tho wind of Its mystery nnd Is ablo to explain convincingly how nnd when It originates. Tho study of n great numbor of observations taken simultaneously all over tho country, nnd In fact all over two continents, hno onablcd tho expert to foresee Just when at night tho layers' ofnlr near tho earth becomo cooled, and ns cool air Is heavier than warm air, a law of physics that Is generally appreciated appreciat-ed theoretically, but usually overlooked over-looked practically, this heavy nlr tonda to raovo down tho hillside. Tho ton-doncy ton-doncy becomes after a tlmo sufficiently sufficient-ly pronounced to produco a gonornl downhill movoment, eventually resulting result-ing a porcoptlblo breeze. That Is what Is commonly designated designat-ed locally ns "tho mountain breeze," and which from Its origin Is practically practi-cally in ono constant direction, though tho Intervention of powerful storm3 may temporarily rovcrso tho custom-nry custom-nry movement. Vico versa during tho day tho prosonco of warmer and therefore there-fore lighter air near tho earth causes n movoment of tho atmosphoro with an upward tendency, creating tho so-cnllod so-cnllod valloy breezes. ln certain favorably fav-orably situated localities tho appear-nnco appear-nnco of the mountain or tho valloy breezo Is as regular as clockwork, tho transitional period being marked by a calm. Philadelphia Record. Alloy That Defies Temperature. Consul Guonther of Frankfort ro-ports ro-ports tho Invention by Dr. Gulllauno of an alloy of steel and nlckol which has the useful property of not expanding expand-ing with Increase of hoat, retaining practically the samo volume under all changes of temperature. By altorlne tho proportions of tho constituents, a metal is obtained which contracts when heatod. Tho utility of an alloy which maintains an unchanged volurno, vol-urno, dospito changes of teinporuturo,. is very great In making accurate moasurlng Instruments, clocks and watches.
