l for ElectrolyticInterrupter. TYPE E coil is similar to type <l A in its construction, ex-cept that it is without condenser or interrupter, as it is spe-cially designed for use with the electrolytic interrupter, which islisted separately. The variable inductance feature is provided. A rheostat is necessary when the elec-Rheosta . trolytic interrupter is used. We furnish two sizes of rheostats ; one for coils of 15-inch spark or more and onefor coils of less than 15-inch spark. The rheostats are made to order for our own special use and are of ample capacity. Prices.

FlGUKli 6 Roentgen Surgeons Special 12 Inch Coil. THIS type of coil has been developed especially for the physicianor surgeon who feels the need of a strictly first-class, up-to-date coil, but who thinks he should not invest in a large and ex-pensive equipment. Twelve inches of spark furnishes the op-par . erator with more energy than the shorterspark lengths and yet does not necessitate the expense of the longerones. Not elaborate in appearance, but well finished, and convenientof manipulation, this type of coil readily adapts itself to any well-appointed office. All the modern features of our regulartype A and type E coils are em-bodied in the electrical construction of this type. The interrupter, which is the vital part, the heart of any coil,is our regular Sell-Star ting- Mechanical Interrupter. This alonecommends the coil in very strong terms, for our interrupter is theonly successful and thoroughly satisfactory mechanical interrupteron the market. Self-starting, capable of runni
