densities had been equal, this point would have been at an equal
distance between the two orbs. But taking the different
densities into consideration, it was easy to reckon that this
point would be situated at 47/60ths of the whole journey,
_i.e._, at 78,514 leagues from the earth. At this point, a body
having no principle of speed or displacement in itself, would

calculated, it would attain this point without speed, having
