The log book of HMS Resolution compiled by William Wales during the passage to the South Seas under the command of Captain James Cook.

Logbook of original observations with the 28-inch Refractor, containing double star measurements by H. Finch and L. Symms. The book is mostly blank, the last entry being a note of the removal of the object glass for protection (ARP).

Logbook of original observations with the 28-inch Refractor, including measurements of double stars and diameter of Mercury. There are also some observations by Mr Shovell, L. Symms and Mr (Cosswill). (No regular observations were made with the 28-inch refractor between 29 October 1915 - 8 April 1919).

Logbook of original observations with the 28-inch Refractor, including: double star measurements; observation of the Transit of Mercury, 7 November 1914, with the guiding telescope Corbett, and a note of a probable air raid on 13 October 1915. Chronometer Kullberg 5054 is mentioned. Two loose pages of notes are included.

The collection consists of Roger Long's Commonplace Books and notebooks as well as posthumous material collected by the College.

Lunar tables in longitude and latitude according to the Newtonian law of gravity, by Charles Mason, 1778. The volume includes a disapproval of Mason's fee from the Board of Longitude [RGO 4/86: 2]; an example of computing the Moon's longitude and latitude; annual equations of the Moon's anomaly and ascending node; and computed longitude and latitude compared with observed longitude and latitude, with corrections, 13 September 1750 - 2 November 1760 [RGO 4/86: 14r].

Mainly ex-RGO Library copies of RGO manuals. Many are photocopied manuals with original RGO library reference numbers on the cover. Includes some duplicates of manuals held elsewhere in the RGO archives. Arranged in chronological order.

Various rough drafts of the solution of astronomical problems.

Note that there is no letter numbered 14.

The Nathy O'Hora papers include the research, publications, and presentations of himself, others, and the RGO. This research notably includes eclipses, a topic to which O'Hora devoted considerable time after retiring. The collection also includes papers and correspondence relating to the Time Department where he worked, his notebooks on various scientific theories and practices, ledgers that he used to record weather data, newspaper clippings, and photographs.

A set of loose pages dealing with problems in ascertaining latitude and longitude at sea by observation of the stars, with descriptions, computations and formulae referred to apparent time. There are also sections on finding the Moon's longitude from the nautical ephemeris [RGO 4/196: 1r], the motion of the Sun's image in a Hadley quadrant [RGO 4/196: 2r], and the testing of other people's hypotheses.
It is not known if the papers are foliated in their original order.

Undated extended manuscript navigation tables.

Notes on Sanderson's lectures in the hand of William Haswell. Includes: lectures on hydrostatics, sounds, optics (with others), mechanics, astronomy, tides, technical chronology, and the doctrine of heat and cold. With (fo. 128) copy of letter from James Bate to Hans Deveille, 3 Jan. 1726

There are two letters with the same date: a.) Chapel on Sunday, possibly Nigels' last service, viewed Venus from the bathroom window. b.) Confirmation of Nigel's last service, drinks in the OCR beforehand, with an invitation to Geoffrey Martin to attend a Charlie Chaplin film.

Preceded by a subject index. The notebook includes biographical notes, notes on letters concerning Urania [Uranus] and comets, and extracts of letters on various topics from cats and carpets to Lady Clive's collection of globes.

Cover page marked Lent 1902, but includes notes annotated up to 1906. Includes (reverse of p60) blank notepaper of the Honorary Secretary of Cambridge University Cruising Club.

Volume of handwritten notes by (John) Thomas Romney Robinson. Inserts pasted or bound into the volume include seven letters and various news-cuttings.

A rough copy of observations of major stars made in 1758 and on a voyage of 1764. The volume includes adjustments to the barometer and atmospheric conditions, 1758; calculations of star positions; the longitude of various foreign towns; corrections to the sextant and quadrant; and calculations to discover longitude.
