'Electron density', 1957-1961
File entitled ‘Electron density’. The material consists of an original folder of graphs of electron density at various heights, compiled by Mrs. Turnbull and others, dated 1959-1961. It includes a research report on the subject by J.O. Thomas, dated 1957.

Envelope containing data and figures, inscribed by A.J. Lyon 'Old Draft of Paper II and odd figures I suggest omitting now'. The material possibly refers to a 1961 paper on the E-Layer.
Exercise book of critical frequency curves, by A.J. Lyon, no date
Exercise book of critical frequency curves, by A.J. Lyon, no date. Only a few pages have been used, at front of book.
Expense list and reading notes, 1694
General notes in planetary physics, in Gregory's hand, with a month's expenses list, probably not in his hand.
Experimentum de magnete percussio ..., 17 February 1695
A paragraph about what happens when a magnet is struck, on the reverse of item 85.
'Extra-tropospheric influences in ultra-short-wave radar operation', March 1946
Extrait de Manouvre des Vaisseaux ... sequuntur ... de Newtoni cogitatio, 1694
A jotting, dated 1694, about a book on how vessels turn (for Gregory was interested in how solids behaved in fluids), and diagrams on the catenary curve, annotated annoted by Gregory and by Newton, almost certainly during their five-day meeting in Cambridge in May of the same year.
'F2 Layer Distortion Diurnal Variation', no date
The material consists of an original file of data for ionospheric stations worldwide, entitled 'F2 Layer Distortion Diurnal Variation', no date. The contents now include only charts of June and December values f'F2 (S.S. min.)/ f'F2 (S. S. max.) (not in Appleton's hand).
'F2 - M3000 S.S. min./S.S. max.', c. 1948-1958
' F2 - M3000 S.S. min./S.S. max.'. The material consists of an original file of data values for Slough, Washington, Huacayo, Tokyo and Watheroo. The charts have used average data from c. 1948-1958 and will have therefore been drawn after this period,
'F2 Region Ionisation Anomalies', no date, c. 1940
'F2 Region Ionisation Anomalies'. The material consists of a 1 page typescript note, no date, c. 1940.
