This arrangement prevented desirable acceleration

valves and Of the Arrangement of the wrists upon
hi. wrist plate il such, that the valves are move al
the tine Of cpering and closing their ports with mo-
ton more rapid than that with which the sliding
valves moved in toe sliding valve engine, before the
adoption of the wrist-pste. Again re have seen
that Mr.. Corliss proposes by his device 10 impart
more raj id motion to the inlet valves 10 closing, and
also more rapid motion 10 the inlet valves 10 open

thus it is s@fn that Mr Sckels' devices have 10

We s.u now erect our stteution to Mr. CJriiss
