Classified papers of the Royal Society Scientific and other papers sent to the Royal Society, presented at meetings of Fellows, or commissioned by the Society. Organised according to a simplified version of the classification by subject area devised by John Lowthorp for his abridgment of the 'Philosophical Transactions'. This arrangement was completed in 1741 by Thomas Birch. Some of the papers pre-date the grant of the First Charter to the Society on 15 July 1662. The Committee of Trades seems to have been associated with the earlier meetings of those philosophers who subsequently became Fellows, and produced a number of practical papers, some of which were written in 1639 and which are mostly found in Volume 3(i). There are still earlier documents, mostly in Volume 25, which may have been included in the gift, in 1667, of the Arundel Library. The majority of the papers in these volumes are manuscript, but a few printed documents occur throughout the series. 1660-1741
