| -2- the top curve will be considered too much, because the system becomes almost ideally automatic. I am pleased to hear that Mr. Royce is to some extent interested in the auto charge reducing switch - I think we have eventually got to come to something of the kind, and when or if we do, that we shall find batterylife still further improved.
