Description | MS/597/3/1a Engraving of Benjamin Franklin
MS/597/3/1b Letter stating Dr Priestley left these specimens of the Circles with him to be produced to the Society. As he cannot be there this evening when he understands the papers are to be read, he encloses them to Canton to present to the company. Those that look at them should be cautioned not to rub them, lest they should be defaced before the company have all had a sight of them. |
