ton? I fnd this statement in a book.
wv. S. T.
A. The Naval Observatory says to
determine his longitude a navigator
or explorer gets the local time from
astronomical observations and the
Greenwich time from his chronome-
ter The difference between the two
then gives the longitude from Green
witch. In the days before accurate
chronometers were available the
moons of Jupiter could be made use
of as a substitute. Almanacs were
published, as they still are, which
gave in advance the time of all the
ecIipses of the four moons, which oc-
cur pretty frequently, and an ex
plorer provided with such an al
manac and a small telescope. by OBJ
serving an eclipse, could get the
Greenwich time at whatever other
place in Europe the almanac was
constructed for, though by no means
so accurately as 1t would beHEot from
a modern chronometer. The use of a
telescope at sea being difficult, this
method of determining longitude was
not suited to mariners. The first al
manac Of the moons of Jupiter ap-
peared at Bologna in 1888.
