This precaution he acquaints the President by a letter dated Paris 26th January 1749 N.S. he takes, not to be prevented in some researches to which he has been led, and to which others may be led, by his solution of the problem of the three bodies. He says he only delays the publishing this paper till he has verified some calculations which he is first desirous of examining. In […]ance of this desire, this paper was now produced by the President who desired leave to deposit it with the Society till Mons[ieu]r Clairaut should give directions for the opening it, and that the secretaries of the Society would for his justification put their own superscription and seals upon it, and that it might be mentioned in the minutes of this meeting. Then the paper was locked up by the President in his [dranver?] at the Society's house till the next meeting that the president's paper containing this account might be mentioned in the minutes, and afterwards sealed upon together with Mr Clairaut's paper (RS, JBC 20, pp. 56-57).
