To find the day of the week corresponding to any date, find
the small letter directly under the month and opposite the
day of the month; the same small letter also appears in the
vertical column that contains the number of the year, and if
the line in which it stands is followed out to the right, the
day of the week is found. Thus, the small letter under March
and opposite 18 is b; b appears again directly over 1904, and
at its right is the word Friday. March 18 fell on Friday in
1904, and also in 1898, 1892, etc. The calendar has other
uses, as for finding the months which begin on Sunday in a
particular year, etc.

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.
