In the manufacture of the hydrogen gas in the apparatus rejircsented in Fig. 5, iron filings immersed in dilute acid are placed in two largo generators. The gas formed by the decomposition of the iron escapes through a pipe fitted to each generator, and passes into a large vessel filled with water, and called a purifier, where it is freed from all its impurities. It then ascends in a conduit, whence it makes its exit ready for use, and to be stored in the steel cylinders. This gas-gener-ator, which is very simple, can be easily transjtorted tti the vicinity of the field of operations of an army. II. Flvixii - —These are usually constructed upon one or the other of the following principles: 1. The imitation of the flapping action of the wings of birds. 2. The sustain-ing of weight and ob
