On Gas Meters—In distinguisliing between dry and wet meters, theconstruction of tlie former is briefly as follows: In a gas-light me-tallic box are placed 2 or 3 bellows Uke vessels, which instead of beinginflated by air, are inflated by the gas entering from the service inflated to some extent an arrangement of sjjriugs and leversforces the gas out of the bellows a;;aiu into the exit-pipe leading tothe burners. The cubic capacity of the chambers (as the bellows like ar-rangements are called), luiving been accurately adjusted, the move-ments of their walls is communicated to wheel-work, wliich b«ingconnected with dials, indicate in tens, hundreds and thousands, th«coQsumption of gas in cubic Fig. 1. Fio. 1. D^ meters are preferred on account as well of not being liable tote affected by frost as of not causing the sudden extinguishing of thegas-light for want of water as may occur with wet meters. Wetmeters are constructed upon a plan devised in 1817, by Clegg. and im-proved by Crossley, and others. Figs. 1, 2, 3 and 4, are drawings ofthis kind of meter, which in the first place of an outer cylin-drical box of cast iron, closed on all sides. In this box is placed adrum of pure block-tin, divided into 4 compartments, bearing upon abell-metal axis, and immersed for rathex more than half its circum-ference in water.
