Copy letter from A H White to Messrs West, Newman & Company 'Poynting, Phil. Trans. ['Philosophical Transactions of the Royal Society'] Diagrams Dear Sirs, Our Treasurer directs me to enquire concerning your estimate for these nine diagrams whether the proposed cost of lithographing (£17-10) is not over-high, seeing that the work is all mechanical; and also whether the figure for the printing, &c (£18-10) could not be reduced by printing two on stone. Yours faithfully, A H White'. 8 September 1891
