The next candidate for the Royal letters appears to be John Moore, of the city of Bristol, to whom they were granted on the 30th of September, 1829, for "certain new or improved machinery for propelling carriages; also for propelling ships, vessels, or other floating bodies, and for guiding propelled carriages, and apparatus for condensing the steam of the steam-engines after it has propelled the steam-engine piston."

The details of all these things would occupy too much space, and the quality of the inventions do not seem to require it from our hands; we shall, therefore, briefly notice the principal heads, and refer the reader to the enrolled parchment "for further particulars."

The propelling is effected by a series of vibrating levers (actuated by a steam engine), and operating upon the running wheels of the carriage. The mode of "guiding propelled carriages" is by means of a vertical spindle carrying is pulley, around which a cord or chain is passed as well as around other pulleys, by which the frame of the fore wheels is placed at the required obliquity to the perch; and the mode of condensing the steam, after it has propelled the piston, is by allowing it to escape from the eduction-pipe, into a box opened to the atmosphere.
