Journal of Navigation, 1977 The following letter to Nature, dated 24 April 1873, might make an appropriate sequel to ‘The history of inertial navigation’ by W. Wrigley in the January issue of the Journal. As well as containing some interesting speculation about animal navigation, which we seem no nearer resolving a century later, the letter includes an introduction to the idea of
