Letter from Herbert McLeod, 37 Montague Road, Richmond, Surrey, to [Joseph] Larmor On Thursday 7050 slips were sent to press [for the Catalogue of Scientific Papers]. He wrote to Clay on the question of one or two volumes, Clay replying that it was a matter for the Syndics and Larmor. The slips have been sent to the end of Measurement of Velocity and Acceleration; seven more have turned up which he will squeeze into proofs. He thought that part 1 would be to the end of Light, but that will be over half of the slips. He will got to the end of Heat and hope that this will make a break between parts 1 and 2. 31 July 1911
