The Anschiitz gyro-compass hasbeen installed on numerous ships ofthe German and Continental navies,and at this writing apparatus is underconstruction for the British Admiraltyfor use on a large vessel. In conclu-sion I wish to acknowledge my in-debtedness to Lord Elphinstone formuch of the text used in the fore-going article, and my thanks are alsodue to Messrs. Anschiitz & Co. forthe use of the accompanying THE GREAT TRANSFORMATION By Henry Harrison SupleeVI.—THE TRANSFORMATION IN DAILY LIFE ONE of the distinguishing char-acteristics of present life ap-pears in the extent to whichpractical applications of scientific ap-paratus have entered into everydayaffairs. It is not so very long agothat the electric light, the electricmotor or the telephone appeared onlyas adjuncts to the display of thescientific lecturer. Even such olderappliances as the steam engine,whether on land or on shipboard,were in the hands only of specialists,trained engineers or operators, andlooked at somewhat as remarkablethings by the layman. The gas en-gine, and its nimble infant, the gaso-line motor, came still later, but they,and most other pieces of mechanicalingenuity, have become very familiarto the public, and been taken alto-gether out of the class of scientificmarvels. To-day the ordinary indi-vidual speaks through the telephone,rides in electric cars or gasoline-driven automobiles, turns
