Description | Rix notes that he has sent by registered post two cards of spectra, for which he asks for an estimate to reproduce them on a quarto plate, at the size of the pattern which was also sent. He further explains that they have sent this work to them due to the high quality of the firm's heliographic reproduction of Dr Josef Maria Eder's paper.
If their estimate is accepted, the plate paper and headlines should match those of the pattern. Rix further states that their estimate should be for 1000 copies including the paper and headlines. |
