mp e a ery usual amount of treatment on one charge, apacity. .f ^ operator wishes to take the coil and battery to a patients home and leave them there till the course of treatment is completed. Or the entire apparatus is light enough to be taken to and fro in a physicians carriage. To reduce the weight of each part to aThree Cells Per Set. . . ,, „ f . ,, r nrnimum, three cells of battery are mount-ed together, in a suitable carrying case with handle. The potentialof each cell being 2 volts, it follows that a set of batteries de-livers current at 6 volts. Two sets will operate our portablecoil very well, but as that means only 12 volts while the coil willstand 20 volts, it is evident that a heavier output from the coil willbe obtained if three sets of batteries are used. For all thera-peutic treatment two sets are ample. The weight per set is about 40 pounds. Price. B3086. Three cells Type P Storage Battery $40.00 34 James G.

Figure 20. Bariym Platirko-Cyanide Fluoroscopes. OUR Fluoroscopes are of the best quality and are provided withremovable screens so that more than one person at a time canuse them in a properly darkened room. The barium platino- cyanide of thesescreens does not lose its water of crystalliz-mncy. ation with resulting decrease in brilliancy of fluorescence, for it is protected by a transparent coating applieddirectly to the crystals of the salt. We recommend these fluoro-scopes as being thoroughly satisfactory in this respect, for they re-tain their original fluorescence indefinitely with proper care. Prices. Fluoroscopes with removable barium platino-cyanide screens. B3090. Size of Screen, 5x7 $12.50 B3091. 6x8 16.00 B3092. 7x9 20.00 B3093. 8 x 10 24.00 Unmounted Screens 25 cents per square inch.
