For some little time past the doctor had noticed with growing anxiety an abnormal fluctuation in the electrical current from the tube. Evidently something was the matter, but what could it be? In vain the doctor tried every conceivable remedy; the trouble increased, and finally the danger-signal itself appeared, warning him that matters had reached a crisis, since this signal was only set for a high amount of disturbance in the current.
The effect of this signal on the three spectators may be readily imagined; but on Flora Curtis it was especially potent. The poor girl buried her face in her hands, and burst out sobbing.
