Copy letter from Herbert Rix, to Messrs Collings & Company Herewith are figures one to six for Glazebrook and Skinner's 'Philosophical Transactions [of the Royal Society]' paper. Rix worries figures two, three, four and six have too much wording for zinc. If the Messrs think the words will not come out well all six should be done white on black. 31 May 1892
