Ifthe galvanometer needle is displaced, the rotatingdrum makes contact with a and c, and the magnetson the toggle arras are energized. The magnets droppawls into the teeth of the rheostat coutroller, andthe tog9;le arms move the rheostat arms so that moreresistance is introduced into the main circuit and lessenergy is imparted to it. Then the rise of temperatureof the reduced quantity of gas becomes less, so thatthe galvanometer needle goes back towards zero. Theamount of resistance added depends upon the number ofcontacts moved over by the rheostat arm; this dependsupon when the magnets d]_ and dg are energized, whichdepends upon the position of the needle a. If Tg-T-j^is much in excess of the proper amount, a makescontact with bg and three additional units of re-sistance are cut in. If, however, Tg-T, is only slight-ly in excess of the
