William Radcliffe Birt
Date:
[19 July 1841]
Source of text:
RS:HS 19.91
Summary:

Fully examined WB's report [on barometer observations]. Agrees to combine British and Continental observations. Curves clearly show atmospheric processes. Likes WB's suggestion of tracing atmospheric wave beyond 24 hours; will propose this to B.A.A.S. Irregularity of Asiatic and South African data.

Source of text:
RS:HS 19.92
Summary:

Cambridge barometer observations. Postponed WB's detailed report until 1842 B.A.A.S. meeting. This year JH will report generally on atmospheric curves and WB's notes. Hopes WB will attend to give explanations.

William Radcliffe Birt
Date:
[1 December 1841]
Source of text:
RS:HS 19.94
Summary:

Heard of WB's bout with typhus. Interest in atmospheric waves should ensure publication of WB's article in Athenaeum. Will write editor on WB's behalf. Awaits completion of atmospheric curves for B.A.A.S. Congratulations on recently acquired office.

Source of text:
RS:HS 19.106 (C: 19.105, 22.166, & 22.167)
Summary:

JH's theory of barometric waves. Comparison with ocean tides. Non-trade winds follow laws of periodicity and are predictable, accounting for previously unexplained phenomena. Attributes rotating storms to interference of two or more wave trains. Will propose WB as director of new B.A.A.S. project to discover laws of weather behavior. Sends payment for WB's expenses. Never saw anything more beautiful than WB's 'Symmetrical Barometric Curve.'

Date:
[7 October 1847]
Source of text:
RS:HS 19.126 (C: RS:HS 22.328)

Source of text:
RS:HS 19.127
Summary:

Lord Auckland [George Eden] asked JH to edit [Admiralty Manual] for officers on surveying and exploring expeditions. Charles Wheatstone will prepare instructions for meteorological observations. Asks WB to write instructions on detecting 'atmospheric waves and barometric fluctuations.'

Date:
[5 January 1848]

From:
Sir John Herschel
To:
William Radcliffe Birt
Date:
[16 March 1848]
Source of text:
RS:HS 19.132
Summary:

Returns WB's draft with JH's editorial corrections. Admiralty has no objection to WB publishing it as separate article. JH will write instructions on 'general' meteorological observations to fill gaps left by WB's and Charles Wheatstone's specialized instructions. Devote time to analyzing existing observations, not to making more.
