| Description | Glazebrook's letter of 7 October, with reference to Mr Smith's two Philosophical Transactions of the Royal Society papers, has been seen by Professor Joseph Larmor who agrees with Glazebrook's suggestion that all the illustrations be reproduced, providing he takes responsibility for the payment of the expenses of preparing and printing the plate of microphotographs and a portion of the cost of preparing the other plate of photographs of silver deposits, in case he needs extra copies for the use of the National Physical Laboratory. |
