Wilmslow Rectory, nr. Manchester - In ascertaining the longitude of a ship at sea WB questions the accuracy of chronometers and the lunar method: The moon should not be used as 'the clock' in the solution to finding longitude. The movements of the moon are so irregular and complicated to be useful. The motions of the sun in respect to the earth would be far superior. If this view is at all new or worth considering, WB will send WW details of his theory.
