her.The connecting wires should be well insulated (^ 193,12) and twisted together (T[ 193, 8). The deflectionof the galvanometer is to be found by reading bothends of the needle (^ 193, /j). The connections of the poles of the first cell (^)are now to be interchanged (Fig. 221, 2) so that itacts… … Fig. 221. and so in turn each cell is to be opposed to the rest(as in 4, 5, 6, and 7). Then A and B are both to bereversed (as in 8), then C and I) (as in 9), then J?and F (as in 10). Th6 student may be interested totest the equality of the cells by opposing A, B, and 0agairist D, U, and # (as in…
