Pièce 70 - Letter from George Airy

4 pp.

Royal Observatory Greenwich -GA does 'not fully understand the case of the Australian diurnal tides. I do not see the difficulty of an inequality both in high and in low water'. WW is not to suppose that he is satisfied with the Irish tides beyond the empirical laws: 'The mechanics of a sea are almost desperate. I could not satisfy myself about the facts on the eastern side of the Irish channel, and therefore I inferred from those on the western side as if the evidence on that side applied to the whole'. GA wishes WW would try his 'translatorial hand on Schiller's Graf von Kabsburg'.
