Royal Society Letters: letters received by the Royal Society, its President or Officers Letters sent to the Royal Society, its President or Officers. Subject matter is both domestic/administrative and scientific. Domestic concerns include such matters as instructions from authors on the publication of papers. The letters on scientific topics appear to be those which were considered of small significance, e.g. giving notice of minor inventions, or appealing to the Society for recognition rather than presenting theories, ideas or observations. 1737-1799
