Description

Two strips showing Draper's spectrum, obtained in December 1872, mounted on a board and varnished. They are probably printed reproductions rather than actual photographs. There are two the same (see 11861), of which this is the less clear and clean. Associated with 11860 (Angstrom's solar spectra mounted in the same way).
