A second to Mr. Hooke, acknowledging the receipt of the diploma sent, and a profession of the great esteem, which he had of the honor done him, and of his zeal to serve the Society in what he was able, for the future as long as he lived.
A third to Dr. Gale, containing an answer to the doctor's address by the last letter, and an account of some farther discoveries made in the juice of plants, animals, &c. Mr. Austin took this letter, and promised to translate it into English against the next meeting, it being written in Dutch.
