| Description | Autograph draft letter signed by sender, with annotations by Sir John Herschel. John Frederick William Herschel'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 William Radcliffe Birt as director of new B.A.A.S. project to discover laws of weather behavior. Sends payment for William Radcliffe Birt's expenses. Never saw anything more beautiful than William Radcliffe Birt's 'Symmetrical Barometric Curve.'
Annotation in Herschel's hand: "n.b. All this mass of writing was in vain"; "Substance communicated to Mr Birt personally July 30 43". |
