[1853. the outlet and inlet valves are at the top of the cj'linder. c' is an inlet, and c" an outlet valve. The air receivers of the four double cylindei-s communicate with each other by connectino- pipes, and thus form, in connection wilh tbe several comnnmicatiug pipes, one common receiver, of so large a size, that as it is asserted, the the elastic force of the compressed air )'eraains veiy nearly the same in the working of tbe engine. The receiver is provided with a guage. The communications between the I'eceiver and the heater, and between tbe heater and the external air are closed by two puppet-\alves. These vah-cs are shown in tlie diagram at (7 and h. The one I will call the vpper and tbe other the lower \-alve. Tbe thermo;neters at I, m, n, serve to indicate the tempeiature of the entering and escaping air. When the working piston reaches its lowest point, that is, is nearly in contact with the cylinder bottom, the upper vah'e is opened by the machine, the compressed air rushes from the i'eceiver through the regenerator into the space underneath the working piston, and the piston is forced up. At two-thirds of the stroke this valve is closed and the heated air actsexpansively to tbe end of the stroke. The lower valve is now opened, and the same body of air esca[)es through it into the vertical pipe ?', which communicates with the external air; passing again through the regenerator on its exit. Tbe Regenerator is an admirable contrivance of Captain Erics- sou's for abstracting the heat, or the greater portion of it, from the escaping air, and restoring it again to an ecpial body of air enteiing the cylinder, to repeat the work performed by the air which has just escaped; that is, for employing the same amount of heat o\-er and over again. The regenerator consists of a large number of disks of wire-netting
