Selling house [in London]; comments on H. S. Boase's writing on annuities.

Knew he would get a speedy answer. Quick, the Bristol bookseller, has sent him an edition of Francis Walkingame's Arithmetic. Thinks JH is right to sell Francis Baily's house. G. B. Libri may wish to buy. His puns are unavoidable. Hopes JH will have his house valued.

Many thanks for his new projection of the sphere. J. L. Lagrange has two papers of 1779 on the subject. John Lee elected president at the R.A.S. He himself has resigned from the council.

Asks what AD knows about the Andersonian Institution in Glasgow, which JH's son Alexander is considering as a place of employment. JH then deals with a problem in probability theory, and concludes the letter with a riddle.
