Another very peculiar arrangement of the _verge escapement_ we show at
Fig. 158. In this there are two wheels, one, _R'_, a small one in the
form of a ratchet; the other, _R_, somewhat larger, called the balance
wheel, but being supplied with straight and slender teeth. The verge _V_
carrying the two pallets is pivoted in the vertical diameter of the
larger wheel. The front view shows the _modus operandi_ of this
combination, which is practically the same as the others. The tooth _a_
of the large wheel exerts its force upon the pallet _P_, and the tooth
_b_ of the ratchet will encounter the pallet _P'_. This pallet, after
suffering its recoil, will receive the impulse communicated by the tooth
_b_. This escapement surely could not have given much satisfaction, for
it offers no advantage over the others, besides it is of very difficult
construction.

INGENIOUS ATTEMPTS AT SOLUTION OF A DIFFICULT PROBLEM.
Much ingenuity to a worthy end, but of little practical value, is
displayed in these various attempts at the solution of a very difficult
problem.
