336 Mr. Perkins’ Method of applying his dion Invention &c. 
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 situ- 
ation connected with a steam engine, without the necessa 
intervention of any steam-chamber, or other reservoir of 
steam 
H 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 genera- 
tor, until the pressure against the steam valve shall cause it to 
rise, valve being so mae as not to rise, except by 
means of such extra pressure as aforesaid. 
“ Fourthly,—For the aed application of such water, 
or other fluid or fluids, so heated as aforesaid, and of 
steam or vapour generated thereby ; whether sach steam or 
vapour be employed through a steam-pipe without a 
steam-chamber, or reservoir to act immediately on 
piston, or to be collected in areservoir or steam-chamber, 
and t to act on the piston, or only for heating wa- 
ter to eenencons other steam, or for any other purpose or pur- 
whatsoever, provided always, that such general ap- 
cation aforesaid be for the purposes of steam-en- 
the mode of applying this, pac toa variety of opera- 
tions in which heating. may be requisite, is embra 
by a second patent to specified in November, and that 
the mechanical construction of the working parts of the en- 
gine will be explained in the s is of the third pa- 
tent, which will be enrolled in m 
The same writer informs | that caret of the new en- 
gines which have been ordered, are at present constructing; 
and particularly, that an coin of about 80-horse power, 
for the purposes of steam navigation, is in considerable for- 
wardness, and will probably be in operation between Lon- 
don and Margate before the end of the present summer-
