When a long, thin wire is to be heated, as in looping, screw downthe suspension-rod C firmly, and raise & 6 by a few turns; when a thickwire or heavy cauterizer is to be employed, release C by a few turns andscrew down b b firmly. By the first proceeding a battery of four cellsin series may be obtained, and by the second one of two cells ofdouble-volume capacity. (See Figs. 7 and 8.) The conducting cords, which should be six feet long, consisting of. Fig. 9. ELECTRO-THERMAL SURGERY. L-11 from one hundred and twenty to one hundred and fifty copper wires ofNo. 30 gauge, bunched together, but not twisted, and covered with silk orworsted material, may be now adjusted, care being taken that the bind-ing-screws are turned down firmly. It is quite important to see that notonly the polar but all other connections, including those in the electrodehandle, should be perfect. The pneumatic agitator should be worked,when needed, by short and frequent compressions of the bulb rather thanby forcible and prolonged insufflation. Before commencing operations,and in order to be sure that all is right, one of the knives had better beconnected and the battery immersed to test its capacity. In operating,the degree and volume or quantity of heat required may be regulatedby the depth of the immersion, the strength of the exciting fluid, or theair-bulb. In nearly all cautery operations, except t
