Copy letter from Herbert Rix, to Mr Edward Bagnall Poulton, St Helens Cottage, St Helens The Royal Society is anxious to have Poulton's exhibit but it would be more convenient for them to have it in June because there is such a rush on their lantern this next Soirée. Rix asks if Poulton would be available for June, if not they must have it in May but he needs to know rapidly. 22 April 1892
