and equal. the line thus described will repre-
sent tae Spiral described by a ship, sailing
due east CT west from simiarplsce. And
since the Equator cuts all meridans at right
angles and a parallel of latitude cuts them
at acute angles towards the ne arer pole, in
consequence OF their converSency, and a ship
sailing from place in parallel Of latitude,
meets all the meridians in advance at ebtusc
angles towards the Equator; Therefore, it is
evident, that the Spiral or LoAodromiC desert
bed by ship sailing due 4. or " from a place
of N. or S. lat. will lie between the parallel
and the Equator, inclning to the latter, if
pursued IN the a. cotton, in which the vessel
sails. And Iince the ship in sailing, meets
the merltians at obtuse angles towards de
Equator, and leaves them at right ARCHES; it
IS evident that the Spiral which she describes
is denticulated on the sides.
a|Ihis theory of SAILING is also supported, by
the consideration that the angle, between the
east and west hnc, is not evanescent, since II
IS not the point from which the-vessel starts, &
its great circle, (the east & wCs, lne) Which
move around the globe but the vessel itself
which begins ITS motion in the great circle,
and welding to the FIRST irnpuse, must move
therein, the hrst moment of its motion, and
consequently recede from the parallel and in
cline towards the Equator.
1t appears from the above demonstration,
that the 10th prop. or the 3rt book of Euclid,
rs perfectly consistent with it since there is
no occasion for TIE object moving due east
or west, tn split the angle contained by this
course and the parallel OF latitude passing
through the place from which the object
moves. Therefore, Mr.. Wallace has misa D.
