332 Mr Perkins’’ method of applying his New Invention , Sfc„ 
steam to be generated from such water or other fluid or fluids, 
at the time of its generation. 
Secondly , — For causing such water, or other fluid or fluids, 
so heated as aforesaid, to escape from under the said pressure, 
and pass at once from the generator into the steam-pipe, where 
it becomes steam or vapour, and in that form may pass thence 
to the cylinder, or to any other situation connected with a steam- 
engine, without the necessary intervention of any steam-cham- 
ber, or other reservoir of steam. 
“ Thirdly , — For the manner of causing such water or other 
fluid or fluids to escape as aforesaid, that is to say, by forcing 
other water or fluid or other fluids into the generator, until the 
pressure against the steam-valve shall cause ic to rise, the valve 
being so loaded as not to rise, except by means of such extra 
pressure as aforesaid. 
66 Fourthly , — For the general application of such water, or 
other fluid or fluids, so heated as aforesaid, and of the steam 
or vapour generated thereby ; whether such steam or vapour 
be employed through a steam-pipe without a steam-chamber or 
reservoir to act immediately on the piston, or to be collected in 
a reservoir or steam-chamber, and thence to act on the piston, 
or only for heating water to generate other steam, or for any 
other purpose or purposes whatsoever, provided always, that 
such general application as aforesaid be for the purposes of 
steam-engines.” 
The Editor of the London Journal of Arts, from which we 
have taken the preceding specification, informs us, that the 
mode of applying this principle to a variety of operations in 
which heating may be requisite, is embraced by a second pa- 
tent to be specified in November, and that the mechanical con- 
struction of the working parts of the engine will be explained 
in the specification of the third patent, which will be enrolled 
in December. 
The same writer informs us, that several of the new engines 
which have been ordered, are at present constructing ; and, par- 
ticularly, that an engine of about 80-horse power, for the pur- 
poses of steam navigation, is in considerable forwardness, and will 
probably be in operation between London and Margate bcfoie 
the end of the present summer.
