| (2) Contd. idea as to just what this extra cost would be, and we trust that you will be able to supply this information at your convenience. In the meanwhile, seeing that we have two other experimental batteries, still in order on chassis, the failure of one of which at any rate may be anticipated in the near future (this one containing three cells without ebonite separators) we think it may be worth while delaying any decision for the time being, as the evidence of the three cells of this battery containing ebonite separators may be useful in this connection, particularly as this case will differ from the one previously examined in having been longer on chassis service as against the shorter intensive service of the other battery on our life test.
