GEOMETRY, ASTRONOAIY, MECHANICS. ONE of the moft interefling rcfearchcs, which the navigators can be at prefent employed in niakino;, is that which relates to the afcertainingr of the length of the pendulum, vibrating feconds, in different latitudes. The indu6lions which have hitherto been drawn from this inftrument, to de- termine the variations of gravity, reft on a very limited number of operations, made by different obfervers, and with different inftruments; and this want of uniformity in the operations mud have a neceffary influence on the certitude of the confequences deduced from the comparifon of the refults. It is evident, that a collective number of opera- tions of this kind, performed with care, by the lame perfons, and with the fame inftruments, is much w^anted ; and the academy cannot too ear- neftiy recommend to the navigators, to profecute this inquiry with all the exactnefs poffible in every place they may put into on their voyage. The determination of the longitudes will be neceffarily one of the principal points, to which the navigators will direct their attention j in order, however, that ftill greater advantages may be ob* taincd.
