Before this letter was written, viz. on the 21st May, the bookseller had received the royal privilege for printing the work; and when it was completed, he sent a copy in a present to Sir Isaac, who received it on the 11th November, 1725. It was entitled, _Abregé de Chronologie de M. Le Chevalier Newton, fait par lui-meme, et traduit sur le manuscript Anglais_, and was accompanied with observations by M. Freret,[95] the object of which was to refute the leading points of the system.[96] An advertisement was prefixed to it, in which the bookseller defends himself for printing it without the author’s leave, on the ground that he had written three letters to obtain permission, and had declared that he would take Sir Isaac’s silence for consent. When Sir Isaac received this work, he drew up a paper entitled, _Remarks on the Observations made on a Chronological Index of Sir Isaac Newton, translated into French by the Observator, and published at Paris_, which was printed in the _Philosophical Transactions for 1725_.[97] In this paper Sir Isaac gives a history of the transaction,—charges the Abbé Conti with a breach of promise, and blames the publisher for having asked his leave to print the translation without sending him a copy for his perusal, without acquainting him with the name of the translator, and without announcing his intention of printing along with it a refutation of the original. The observations made by the translator against the conclusions deduced by the author were founded on an imperfect knowledge of Sir Isaac’s system; and they are so specious, that Halley himself confesses that he was at first prejudiced in favour of the observations, taking the calculations for granted, and not having seen Sir Isaac’s work.
