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.'
