Unpublished manuscript, 'The measurement of tides by means of the Favé pressure gauge' by J [Joseph] Proudman, A T [Arthur Thomas] Doodson and R H Corkan The measurements and analyses described in this paper are made with the object of calculating the variable parts of the components of the horizontal gradients of pressure in the sea. Three models of the Favé pressure gauge are used in these experiments. Annotations in pencil and ink throughout. Includes eight pages of tables, a diagram of experimental apparatus and a graph showing the height of the tide in centimeters. Includes a letter dated 12 December 1939.
