criminal was laid on a cart wheel with his legs and
arms extended, and his limbs in that posture were
fractured with an iron bar. In France, where its use
was restricted to the most atrocious crimes, the
criminal was first laid on a frame of wood in the form
of a St. Andrew's cross, with grooves cut transversely
in it above and below the knees and elbows, and the
executioner struck eight blows with an iron bar, so as
to break the limbs in those places, sometimes finishing
by two or three blows on the chest or stomach, which
usually put an end to the life of the criminal, and
were hence called coups-de-grace -- blows of mercy. The
criminal was then unbound, and laid on a small wheel,
with his face upward, and his arms and legs doubled
under him, there to expire, if he had survived the
previous treatment. --Brande.

(Zool.),
any bird of the family Trochilid[ae], of which over one
hundred genera are known, including about four hundred
species. They are found only in America and are most abundant
in the tropics. They are mostly of very small size with long
slender bills adapted to sucking nectar from flowers, and are
noted for the very brilliant iridescent colors of their
plumage and their peculiar habit of hovering about flowers
while vibrating their wings very rapidly with a humming
noise; the wings are specialized for hovering flight, but
they can also dart forward and fly quite rapidly. They feed
both upon the nectar of flowers and upon small insects. The
common humming bird or ruby-throat of the Eastern United
States is Trochilus colubris. Several other species are
found in the Western United States. See Calliope, and
Ruby-throat.
