✦ Synopsis

Condensation of Steam in the

Steam-Jaekets.

--The mean results from experiments A, B and C, show, that of the total weight of steam evaporated in the boiler, 3k per centum was condensed in the steam-jackets of the cylinder. This per eentum is greatly less than the truth--probably one-eighth less--owing to the causes hereinbefore stated. Now, as the jackets were supplied with boiler-steam by a small independent pipe, and had no communication with the main steam-pipe, no water could have been primed over into them, and the whole of what was found in them must have been due to the absorption of heat by the steam within the cylinder, for the insignificant quantity of heat lost by external radiation from the small and well protected surfaces of the jackets, need scarcely be allowed for. This absorption of heat from the jackets by the working steam within the cylinder, must have effected some economy in the production of the power.
