Light Without Matches

hght instantly without the uso of matches and without the danger of setting things on firo, take an oblong phial of tho whitest and clearest glass ; put into it a pieoe of phosphorous about the size of a pea, upon which pour gomo olive oil, heated to tho boiling point, fllling the phial about one-third full, and then seal the phial hermetically. To uso it; remove the cork and allow the air to enter the phial, and then re-cork it. The whole empty space in the bottlo will then becomo luniinous, and the light obtained will bo equal to that of a lamp. As soon as the light grows weak its power can be increased by opening the phial and allowing a fresh supply of air to enter. In winter it is sometimos uecessary to heat tho phial botwecn tho hands to .increase Huidity of the oil. Thus prepared, the phial may bo used for six montbs. This contrivance is now usod by the watchmen of Paris in all magazines where explosivo or inflummnble materials are stored.
