Copy letter from William Bate Hardy, Secretary of the Royal Society; to the Master of the Gardeners' Company; Bakers' Hall, Harp Lane, E.C.3. 'You will see from the enclosed that the unfortunate error in the table list was entirely our fault. It crept in between settling the diagram of the tables and printing off the list. I much regret that so untoward an incident should have happened.' 2 December 1924
