TitleCopy letter from Herbert Rix, to the Swan Electric Company
Date28 June 1894
DescriptionRix would like to know when Professor Hartley's plates will be delivered, as they have been in progress for an unusual amount of time. He also asks for an estimate for one quarto plate of spectra for paper number 102 by Hartley, to include five bands on cards which have been marked by the author as plates 1 and 2, but which can be combined on one plate. The second plate will have to be enlarged from the negative to match the first plate. A separate estimate is requested for quarto plates for paper number 107 from the cards marked 1-6.
