Having always supposed, and even cherished the idea, that you were a member of the Imperial Academy of Sciences, which is at St. Petersburgh under my direction, I was greatly surprised, when reviewing the list of its members some days ago, I did not find your name in the number. I hastened therefore to acquire this honor for the academy, and you were received among its members with an unanimous applause and joy.

In the mean time be assured, that it is with the greatest pleasure, that I profit of the present occasion to give you token of my regard and veneration for your eminent character, and that I shall always recollect with pride the advantage I had to be personally noticed by you.
