Batteries. You will be pleased to hear Messrs. Peto & Radford are proceeding with production of Batteries with the thicker type separators, i.e., .6 m {Mr Moon / Mr Moore} /m thick instead of .4 m {Mr Moon / Mr Moore} /m as hitherto, at no extra cost over our present price, and expect to have supplies available in about 3 months time.
