'Copy of a Letter addressed to Col. Sykes by the Revd. Dr. J. Stevenson on an Inscription from the Nana Ghat, Bombay (Mumbai), 14 May 1851' in which he writes that the Cave Com. of the Royal Asiatic Society has acquired the services of a young man, Mr Brett, who has a taste for the study of languages and makes very good sketches. He is engaged in making exact facsimiles of all the Western India Inscriptions. He also writes that his Society has agreed to reprint the three volumes of the Transactions of the Bombay Literary Society. In the third volume, he writes, is an inscription from the Nana Ghat which he had visited recently and so wants to add to what was already known.
