The rheostat has a single pole switch sothat closed 25 amperes are available for opaque projection—open, 12^ amperes are used for lantern slides. The body, dark chamber and slide projector are of plan-ished steel—and the whole outfit is guaranteed against anydefect whatever of material or construction. It is the very latest, most improved outfit on the marketand is equipped with high grade lenses—an exceedingly good,efficient, honest outfit—not to be equalled at the price andhard to beat at any figure. 30 McINTOSH STEREOPTICON CHICAGO, V. S. A. McINTOSH (Fig. 1) The ]\Iultitjpticon will satisfy the cleniand for an instru-ment which projects opaque objects, without inversion ortransposition of the imas:^e, and which can also be used atpractically an unlimited distance from the screen for lanternslide projection. Schools and Y. M. C. who desire a thoroughly effi-cient, high grade projector, find the ]\Iultiopticon just that,and also simple and easy to operate, mechanically and optic-ally perfect-—in short, an ideal instrument for use in its ownparticular field. iV motion picture mechanism can be addedto it at any time. For school use, it can be built for microscopic, vertical,polariscopic and spectroscopic, physical and chemical experi-ment; in fact, any sort of projection. The Multiopticon in its simplest form, is for lantern slideand opaque projection interchangeably and is ordinarily fittedwith IS focus 4 diameter objective for opaque projectionand 8 focus I
