Instead of the original arrangement for regulating the escape of 
ip as shown at g, fig. 2. Also the 
tube cg, which is not capillary but somewhat larger, is filled with 
mercury and thus remains during the combustion. ‘The filling 
is conveniently effected by pouring mercury into the gasometer 
through the tube e, fig. 3, until it passes the point g, fig. 2, and 
flows out in a constant, regular stream at e, which is closed with 
a piece of soft wax. The screw-slip being closed, the gasome- 
ter is ready for use.
