CH. I] SOME AMERICAN MAGIC LANTERNS 59 § 98. If the lantern table is on a concrete floor which is damp the operator is liable to get a shock unless he stands on a mat or board or other insulating material, provided some part of the circuit is grounded (see § 689). SOME EXAMPLES OF AMERICAN MAGIC LANTERNS FOR THE DIRECT CURRENT ARC LAMP § 99. The following examples of American Magic Lanterns are introduced to give the reader some notion of the lanterns on the market which can be obtained at any time and at a very moderate cost. In subsequent chapters will be found pictures of lanterns for the different forms of radiants, and for two or more kinds of projection (combination apparatus). In the appendix at the end of the book will be found the addresses of some of the great manufacturers in all countries with the prices for the different complete outfits for the various forms of projection. FIG. 32. MAGIC LANTERN IN OUTLINE TO SHOW THE PARTS. (Cut loaned by Williams, Brown & Earle).
