Single manuscript letters or small groups of related documents considered too small to be added to the Manuscripts General series. Includes various document formats. The collection contains all manner of papers by, about or belonging to the Fellows of the Royal Society. Subject matter covers all branches of the sciences and includes non-scientific material. Current accessions are limited to materials not generated by the Royal Society, but acquired by gift or purchase; these usually number less than 10 items per accession. This has not always been the practice, so that the collection also contains relatively large groups of papers, occasionally on Royal Society business.

Letters from Sir Robert Moray to his friend Alexander Bruce, Earl of Kincardine, also known as 'The Kincardine Papers'. Bruce was sick of the ague in Bremen for part of this time, and the letters were written to alleviate the tedium of of Bruce's illness, hence ranging over topics which might not otherwise have been the subjects of correspondence. They include accounts of chemical experiments in his laboratory, his interest in magnetism, medicine in all its aspects, horticulture, fuel, whale fishing, its risks and profits, coal mining, water wheels and tide mills, stone quarrying and the various qualities of different stones, the pumping works needed for undersea coal mines at Bruce's home at Culross in Fifeshire, even to the trees whose wood was best for pipelines, and the diameter of the bore best suited to the purpose. Familiarity is shown with mathematical and surveying instruments, with music, and all sorts of mechanical devices and especially clocks and watches, more particularly the taking out of a patent in respect of a clock for use at sea for finding longitude. Bruce is advised on the choice of books over a wide range of subjects. Moray includes anecdotes to amuse his ailing correspondent; he describes his quiet life and is enthusiastic about many of his chemical experiments. Notable at the end of the letters Moray added what he described as his Masonic signature - a pentagram which also occurs in his crest.

Written in England. Contains the curious characters known as the Boetian contractions, and is a valuable document for the history of arithmetic.

Letters from various scientists to Walter White, Assistant Secretary of the Royal Society. With occasional material addressed to Charles Richard Weld and others. Usually on Royal Society business.

The archive correspondence can be characterized as the routine treatment of important events. In 1863, for example, Richard Owen wrote to White with brief instructions for his paper describing the feathered dinosaur archaeopteryx. Occasionally the letters are more significant for the Society's history. In an extended note of 1865, ex Royal Society President the Earl of Rosse 'a plain well-grown man, farmer like in appearance' discussed the merits of signing an election certificate for Alfred Lord Tennyson (1809-1892). 'My opinion...was that it would be better to take the broad view and to elect men of great abillity...so as to strengthen the Society in carrying out, in the largest sense, its great object, that of improving natural science'. Tennyson was duly elected, an event which must have pleased White. The assistant secretary had become friendly with the Poet Laureate in the 1850s and White's published diary left a vivid picture of Tennyson reading aloud his Arthurian romances in the offices of the Royal Society.

Copies of outgoing letters from the President, Officers and Assistant Secretaries. Each page may contain up to four copied documents. Volumes are numbered 1-73 with an additional volume for the period January 1901-November 1904.

A series of (generally) printed material relating to, and commenting on, the Society's activities. The press cuttings and scrap books contain cuttings from newspapers interspersed with other printed matter, and occasionally items of manuscripts. The remaining volumes are concerned with particular events or subjects, such as 'HMS Challenger 1872-1895' or 'National Antarctic Expedition 1899-1904'. There are three types of volumes; the first volume is for the years 1846-1876, but therafter two types of book were kept;

a) biographical - 12 volumes, 1872-1910

b) general, 10 volumes 1885-1910.

These were discontinued for a short period, then merged: 36 volumes, 1918-1976. Thereafter newscuttings were photocopied and kept in monthly bundles.

A small collection of photostats or photocopies of manuscripts held in other institutions, but of some relevance to the Royal Society and its own Archives. The series largely consists of groups of correspondence, notable letters to Julius Plucker (PH.1) letters of Hevelius, Newton and Flamsteed (PH.2) and of Edmond Halley (PH.3) There are some records of other institutions, including a minute book of the Physiological Society 1876-1892 (PH.9), and copies of Rutherford's correspondence at the Cavendish Laboratory.

The manuscript versions of papers published by the Royal Society in the 'Philosophical Transactions'. The series has many points of interest, which include authors' corrections to manuscripts, and the presence of original illustrations in various media (drawings, watercolours and photographs) bound in the volumes. Not all of the material printed in the 'Philosophical Transactions' relating to Society business survives, but manuscript examples of meteorological observations, lists of presents and annual indexing may be found in volumes 8, 9 and 12.
Papers are usually bound into vellum-covered volumes by year of publication, although a few (volumes 4, 5, 8, 9, 12, 17, 73-75) are loose, boxed items. Several gaps appear in the collection, notably for the period 1825-1839 (volumes 18-22) and any year may lack one or more papers; these omissions are noted at the beginning of each part. Despite this, the series constitutes a large, relatively complete run.

Letters and other Papers of the Hon Robert Boyle. The Letters cover Boyle's correspondence; in addition to the letters by scientists such as Hartlib, Beale, Southwell, Wallis and Cole, the series contains letters from members of Boyle's family (Viscountess Ranelagh in particular). There are 37 letters of Boyle's preserved, and substantial blocks of papers from religious figures such as Robert Sharrock. The Papers cover his philosophical, scientific, theological and other interests, and cover most aspects of his life and works.

The Register Books contain copies of scientific papers submitted to the Society - the original documents may be found in the Classified Papers. The papers were transcribed in order to establish their precedence for a particular discovery or idea. Therefore not all communications to the Society were registered in this manner, but only those judged to contain some significant material. Dates as listed are those in which the paper was communicated to the Royal Society; dates of writing, where given, are included in the description of each paper. Many of the these papers were published in 'Philosophical Transactions'.

Letters sent to the Royal Society, its President or Officers. Subject matter is both domestic 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.
