The British Thomson-Houston Co. hasachieved success in the development of a prepayment meter which itis now prepared to offer, for use on continuous current circuits. This meter consists essentially of two parts—the electrical meterproper, and the mechanical prepayment mechanism, a general ideaof which can be obtained from Figs, i and 2. Both the meter and prepayment mechanism are contained withina strong cast aluminum dust-proof case, which is of neat appearance,and occupies a space of only 8f^ x 10^ x 5 inches deep. It is soconstructed that by the removal of the cover, which is held in placeby four sealing screws, easy access to all parts of the meter andmechanism is obtained. A window is fitted to the cover, throughwhich both the meter dial and coin indicator are visible. The meterdial registers the total number of un
