I ! I ll l I; 1 I TWO GREAT IMPROVEMENTS la Edison Phonographs and Standard Records. First: The New High Speed Hard Wax Moulded Standard Records. Second: The New Bdison Reproducers for all xnuchines except GEM type. The High Speed Hard Wax Moulded, Edison Records are made of an entirely new composition, much harder than the ordinary wax Record. They may be handled without fear of spoiling the surface with finger marks; they are not, however, indestructible. Their speed is 160 revolutions, faster than ever before successfully attempted on Standard size Records. To reproduce them perfectly, it is absolutely necessary that a Phonograph should run at the same speed, that is, 160 revolutions per minute and no more; the varia- tion of a few revolutions making a vast difference in the reproduction. These Records are made from a permanent MASTER, and no care or expense is spared to make it perfect; consequently, all Bdison Records made from this MASTER are exactly alike, and are all exact copies of the PERFECT MASTER for loudness, clearness, naturalness and depth of cut. Flaws and imperfections are a thing of the past. The New Edison Reproducer has two ab- solutely new and important features. First: a built- up diaphragm of mica, very highly sensitive, yet not liable to breakage as with the crystal diaphragm. Second: a new form of sapphire shaped like a button, and so placed in the Reproducer arm that the edge of the sapphire tracks the groove of the Record. The con tact's unQce is very much smaller than that of the old ball, and consequently can follow more exactly the undulations—the ins and outs—of the track on the Record. No longer will the sapphire have any tendency to lump from crest to crest in the groove, but, the undulations being longer and more gradual (due to higher speed), and the contact sur- face of smaller size, the new button Sapphire will follow every tiny hollow and crest in the Record track, faithfully in and out, and will in turn convey these movements through the Reproducer arm to the diaphragm, and from thence, in the shape of sound vibrations, through the horn and to the ear •f the listener.
