If the resistance in the circuit is sogreat that this limiting value can not beattained, the interruptions do not takeplace. Curiously enough, two of these inter-rupting platinum anodes may be workedin parallel and the effect is that the in-terruptions then occur only upon the at-. FIG. 3.

Whether this value will be thesum of the limiting values for each in-terrupter is not determined. The run-ning of interrupters in parallel suggeststhe provision of a set having values of 5,2, 1, as in a set of weights, so that byswitching in parallel or using one or theother single, any value in units from 1to 10 might be obtained. It is to be doubted, however, that theinterruptions wilt be so sharp with thisform as with a single interrupter. Trialsmade with those at hand seem to indi-cate this as a fact. This doubt can besettled by further experiment. Fig. 3 shows another suggestive ar-rangement. Let B be an electrolytic 626 THE AMERICAN X-RAY JOURNAL. interrupter having four platinum pointsimmersed.
