Item 36 - Letter from George Airy

3 pp.

Flamsteed House, Greenwich - Their young lady's name is to be Elstrith, and she is fat and flourishing and her mother is well but weak. It was Airy who brought the tide disturbance of January 3 to the attention of the Admiralty: 'The tide in the Thames was 6 feet lower than it ought to have been. I have received several of the Admiralty observations: the tide at Leith seems to have been scarcely affected' [see Airy to Whewell, 21 January 1841]. Airy gives a long descriptive and mathematical answer to Whewll's query regarding oblique arches.
