TUBE RAILWAY BETWEEN DENMARK AND SWEDEN.

A definite proposal lias boem put lorward for tlio ooiiNtniotiion <yf ,a tiinmil lioUvcen Dennnark ciiiiid Sweden, .starting at Copewlwigen, and coinii.t'cl iiio; up with .Mailone. C'oiinectifiii would lie mad*' ion the wav with tlw small islands of Amagw mid S;iH ho]rn, and t«he electric tniiiiKs wiiich it i.s propascd to work tlirons?ii tli'p tunllHi would immi on tlio .surface ol tlu'Ke islands in order to reduro the uiKk'i'ffroiind jounncy as ntiitili as If the scheme is carried lout i.t is <-.stima.ted that the trip could bo made in ]| hours. WHAT FLIGHT DEI'MN'DS OX. "Mathematicians Iwive fldways told ns," says Sir Hiram Maxim," "thait a Hying machine would bo ipmsiihle .ju.st as soon as a suitable iiH.tiir foi the purpose wns discovered. For this retmnkahle motor we ane indelitcd to those who have spent hundreds of thousands of pounds in the development of (\spei"iii.ll.v those ot' the racing type. Tlio domestic goose weighs 12iibs, and is a,l>le to fly, and it is said, that in doing ho she develops the tweilftih part of horse power. Gasoilinc motors have ,already hoen mack tha;t dovelcp one-hoivse power f(?r livery -III) (if weigh,t, or say oiie-lioiKe power with the weighit of a sin all jmi;nyard fowl, and I find that thvire is ia possibility of reducing this weight to ,a;l)out two and a half pounds, providiing that all the. (xi-rtLs are made </f high gnulo-and oarefnlly tempered .steel. Many philosophers have nwiiintained, .and with reason, that il mankind was ever to mnistei the fnir it would -ho in t'lie very n-att-ure things, lie necesisar.v to iniiitia.te Natuire's flying in,achino.s- and depend ialtogfither upon dyinaimic (incrgy iiiistrtid ot the htiovancv of gas." DERP BREATHING AND HEALTH. 'I lie alimosphere contaiins properties upon wh'icli every ihreathiiig thing is dependent for existence. Food, 'When taken into the system, is ailmlutely va.l nnitil' combined w.i'itih oxygen. By this eomlvination the body obtains vibratory heiat and motion, just as an engine heconics potent and active froiin its fuel supply. All life i.s dependent upon oxidation, which lneans combustion or burning. Tho more air or oxygen taken into the system the greater the vitality. Air is free. \\ ore we obliged to pay for it mi so much per pound as wo do food,, we should value it more highly. Breathing is the most important act of our lives, yeit less than one per cent of huiinauity breathe properly. Normal lungs take in, from twenty to thirty cubic inches of aiir at e.nch .inhalation. Lungs rendered abnormal by restriction, disease, or from one-!third to one-hailf less than that a-innunit; wlkilo lungs developed by deeip breathing nuay be made to exnairl sufficiently to inhale six ,times the amount of normal lungs, or from 170 to 180 cubic inches of air at each inhalation. Air should never enter the lnng> bv way of the mouth, but 'alway.' tli rough the nostrils, which nait'ire has provided with cava ties calculated to warm it and arrest -any poisonous exere.tions or gemiis before reaching the delicate It/issues and cell walks of the lungs, buth of which hiv most susceptible to cold blasts and foreign matter. The vitality o! the tissues is de,peudont on the oircußtio''n, of It lie blood and lymph therein,' and the cirouki.tion is dependent upon th.'' respiratory organs. Every cubic inch of air drawn within the limes is eithei coiudiUoive to health or disease. Consequently. discriminative* breathing has inuch to do with prolonged life. Diixv.-'tly at the waist-line rests the diaphragm, a powerful orgaw acting as a bellows for the entire body? With each respiration this muscle .-'honld expand, for upon its ncteiicv depends largely the circulation of tlio blood. Tn the norma! individual there is all equal amount of waste and supply, but when the latter over-balanc-es the former, the stomach becomes so crowded "'ith iinassimilaited foods as to render both the digestive aim:! respiratory organs una Lie to perform their functions without difficulty. At such times these foods ferment and decay, thus generating poisonous gases 'which 'sooner o7 later debilitate the system and makeit an open vehicle lor the carrying of all mainner of genus aiiid disease. Thousands of people are suffering from an over-amount ol physical food and a lack of air food'. Too much air cannot be taken into the lungs, for by its absorption, /the physical fowl i.s easily digested and the vital forces and electrical curreinlts are increased, the results of which am buoyancy, health, and longevity.
