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 11862), of which this is the cleaner and clearer, but has damage to the upper strip. Associated with 11860 (Angstrom's solar spectra mounted in the same way).
