Data on sunspot numbers, c. 1935-1962
The material consists of data on sunspot numbers, mainly of sunspot cycles at various stations. The data covers. 1935-1962 with some charts undated. It includes some work by C.P. Bell
Data, photographs, etc. sent by R. Naismith to Edward Appleton from Slough, c. 1944-1949
Data, photographs, etc. sent by R. Naismith to Edward Appleton from Slough. The material is similar to that with the correspondence in Coll-37/C.407.
Data, tabulating monthly medians of fF2, 1944-1958
The material consists of a large hardcover spiral-bound folder of data, tabulating monthly medians of fF2 from several observatories over several years. Composite tables for 1953 and 1954 appear on the front pages. Dates covered are 1944-1958.
De affirmanda parallaxi magni orbis, cogitatum Hugenii, June 1693
A transcription of Christiaan Huygen's argument that because stars' observed radii are so insensibly small, the diameter of the earth's orbit relative to the stars' position is also insensible, and thus the parallax measurement, which ought to prove or disprove the Copernican layout of the heavens, is useless.
De Antlia Pneumatica ..., 1681
Notes from a trip to London in May and early June of 1681. Gregory saw Boyle's pneumatic pump (an 'antlia' is a siphon) and a method of making 'leaves' with molten glass and water. One Mr Lamb discussed copper engraving with him. He saw Newton's reflecting telescope in Gresham College.
De gyratione Globorum de collisione mutua Probl: Halleianum 3, c January 1695
Treatment of Sir Edmond Halley's method of finding the rotary motions produced in two spheres by an oblique impact. Appears to have been written in a hand other than David Gregory's, [Halley's?] though the title is clearly in his.
De resolutione equationum cubicarum, 1684-1696
Notes on a universal theorem on the forces on inclined planes, possibly part of his notes on Huygen's Horologium Oscillatorium, now lost.
'Declination Sq (γ) 1948-62', 1948-1962
The material consists of a folder created by Edward Appleton entitled, 'Declination Sq (γ) 1948-62', containing extensive data and curves for various sunspot periods, and including work on the elimination of seasonal anomaly. It includes a 1 page manuscript note by Appleton.
