An international system of electro-therapeutics : for students, general practitioners, and specialists . yW. E. Ford, of New York. A cut of the small portable cautery isshown (Fig. 98). It is put up in hard-rubber or glass jars, with a screw-top cover, hermetically sealed so that the acid cannot spill out, andis inclosed in a polished hard-wood case holding either one or two-cells and a rheostat, and is best adapted to take out to an also makes other types of cells, which are best adapted to stationaryuse. Any one of the cells has sufficient power to heat a small cauteryknife. Any two of these cells will heat the largest-size knife or loop, A-304 BLEYER. and will light a small lamp. The only difference in the cells is the lengthof ampere hours they will run, they all having the same electro-motiveforce. In my discussion on batteries I have spoken of the Edison-Lalandecell in extenso^ but I must say a few words regarding these cells forcautery purposes. There are many of them at present in use in the bestoffices and institutions throughout the United States. This cell has now. been brought out by the Edison Manufacturing Company, in a form thatrenders it peculiarly efficient. Eight of these cells, each in a rubber case, are placed in an oakbox and connected in series b}^ means of nickel-plated straps. The re-sistance is included in the outfit, and is placed in a very novel mannerin the top of the case, on a little hinged lid that can be thrown up so asto expose all the batteries clearly to view. This resistance is in theshape of metallic tape, and operates after the manner of a fishing-reel orordinar}^ yard-measure. It is pulled out to any length as required, andwhen the needed resistance is obtained is held at that point. As the GALVANISM. A-305 battery falls off, it can be released and rolled up automatically either allat once or gradually. As is well known, the usual cautery knife requires a considerablevolume of current to keep it at white heat—say
