Copy letter from Herbert Rix, to Mr Fowler The proof was hurridly sent to him last night, with no time to write and explain the difficulty. Joseph Norman Lockyer informed Rix that there was only one cut in the paper, so when a figure arrived with it they assumed it to be a duplicate of the one already in hand. They are unsure if it is a different diagram from the one of which Fowler has received proof, likewise with an addition. He asks if it is only the addition to be done, or the whole diagram. Rix asks that he be informed quickly, and if it is to be done that the diagram be sent in so it may be completed by Thursday. 20 February 1889
