Sayfa 99 - That the squares of the times of the revolutions of the planets are as the cubes of their mean distances from the sun.
Sayfa 105 - When in any investigation the understanding is placed in equilibria, as it were, between two or more causes, each of which accounts equally well for the appearances, as far as they are known, nothing remains to be done, but to look out for a fact which can be explained by one of these causes and not by the other.
