Letter from George Gabriel Stokes, Lensfield Cottage, Cambridge, to Charles Vernon Boys Stokes has made calculations on the radiant heat of the Moon and thinks that it might be detectable during an eclipse. Once he had his result he recalled having heard a lecture in which it was remarked that it did not seem to matter whether a bright or dark lunar surface was observed during a sweep of the Moon. He thinks it may have been Boys in 1890 but wonders if this is a false memory. Stokes muses on how curious memory is before stating that the total eclipse of November next year would be a good observing opportunity. 30 March 1900
