1. The lectures on 'Mr Fox Talbot's Calotype Process' were started in July when the Royal Polytechnic Institution's new rooms onto Cavendish Square were opened - they met with great success. Undoubtedly some visitors also came to see Richard Beard's Daguerreotype studio, based there. See Doc. No: 04457.
