Note 621 — Chapter XII · FREE-MASONRY.
Reading edition
Feyjoo, Cartas, T. IV, Cart. xvi. This letter must have been written between 1751 and 1754, as it alludes to the Centinelo, while the second edition of the latter alludes to the letter. Feyjoo refers to another recent book on the subject by Fray Juan de la Madre de Dios, which I have not seen.
