sixty-four degrees. Consequently, at the moment of firing the
visual radius applied to the moon will describe, with the vertical
line of the place, an angle of sixty-four degrees.

These are our answers to the questions proposed to the
Observatory of Cambridge by the members of the Gun Club:

To sum up--

1st. The cannon ought to be planted in a country situated
between 0@ and 28@ of N. or S. lat.

2nd. It ought to be pointed directly toward the zenith of the place.

3rd. The projectile ought to be propelled with an initial
velocity of 12,000 yards per second.

4th. It ought to be discharged at 10hrs. 46m. 40sec. of the 1st
of December of the ensuing year.

5th. It will meet the moon four days after its discharge,
precisely at midnight on the 4th of December, at the moment of
its transit across the zenith.

The members of the Gun Club ought, therefore, without delay, to
commence the works necessary for such an experiment, and to be
prepared to set to work at the moment determined upon; for, if
they should suffer this 4th of December to go by, they will not
find the moon again under the same conditions of perigee and of
zenith until eighteen years and eleven days afterward.

The staff of the Cambridge Observatory place themselves entirely
at their disposal in respect of all questions of theoretical
astronomy; and herewith add their congratulations to those of
all the rest of America.
For the Astronomical Staff,

Director of the Observatory of Cambridge.
