Abstract
WE have been analysing the longitudinal residuals of Neptune (N), partly from sheer interest aroused by the discordance between the pre-discovery position of N and its currently accepted orbit1 and because colleagues (already conducting a photographic hunt for a hypothetical tenth planet) sought our assistance in narrowing the field of search by using perturbation theory.
