| Sheet No.2. discussion; but we would just like to point out that for such leakage we must be in the same category as other makers, namely, when the battery is under charge the conducting electrolyte is literally dripping from the lid{A. J. Lidsey} between the main terminals. This state of affairs, as stated before, is common to all batteries. Handwritten Note: Not matter when on charge We notice you do not state a limit of weight or size which is used on your 20 H.P. Cars, and we hope you will let us have this figure. We shall be extremely interested to hear to what tests you have put our cells, and the result of same, as from the short time we have been on the market we have had some extraordinary results from various Government Departments and Public Bodies who have tested these batteries.
