As I propose to make some researches concerning the difference of the meridians of the principal Observatories of Europe, which I am persuaded can best be ascertained by the occultations of the fixed stars by the moon; it would be of great service to me to be furnished with the observations that have been made, or that will be made, this year, of the occultations of α or of γ Tauri by the Moon. I beg, therefore, Sir, you will please to desire Mr. Maskelyne to communicate them to me, towards the beginning of the next year, directed to Mr. Euler, secretary of our Academy. It would also be of great use to me to have the observation of the occultation of the Pleiades by the moon the 15th of March, 1766, in case it has been taken at Greenwich.

XXV. Extract of a letter from Mr. Lexel to Dr. Morton. Dated Petersburg, June 14, 1774
