“Such is the ingenious Theory of the Aberration, which Mr. Bradley published in the year 1727, and which was received by the whole learned world with the applause that it merited. M. Clairaut, of the acedemy of sciences at Paris, afterwards made this discovery the subject of a Memoir, which he printed in 1737: In this Memoir, he examines the principles on which the Theory of the Aberration is founded, and gives the necessary rules for putting it in practice.”
