It is ex-pected that the coil will be used on the i 10 volt direct current; butin the event that batteries must be used the expense of the rheo-stat can be dispensed with and the coil furnished with batterywinding without extra charge.

Quick Radiographs. Figure 7. Roentgen Portable 9 Inch Induction Coil. OUR portable coil is the most satisfactory and most powerfulportable coil on the market. Some operators are using our portablecoil for dental skiagraphy, and are gettingthe best of results in from two to five seconds. Still others areusing it with the most satisfactory results for general radiographicwork, and the ease with which they obtain negatives of first qualityplaces this coil in the same class radiographically—with the largersized coils of other makes. Ask us for references on this point. Originally this coil was designed fortherapeutic use in the home of the patientand its radiographic successes are merely incidental proofs of thegeneral high quality of our coils. It possesses all the desirable fea-tures of a portable apparatus for the at-home treatment of patients. The weight of the coil is divided into twoparts, between two cases, one containingthe transformer, i. e., the primary coil, and secondary coi
