First appearance of Huggin's series of spectra done with his new spectroscope made of six prism of heavy glass as a preliminary investigation to the work with the spectroscopy of the stars with the star-spectroscope, as it was necessary to have convenient maps of the spectra of terrestrial elements. Huggins devoted a large part of 1863 to the making of 24 such maps with a train of six prismes. These maps were published in the paper offered.""William Huggins (1824-1910), English astronomer, a pioneer in spectroscopy and photography. He examined spectroscopically the chemical constitution of stars and comets, and the gaseous nature of planetary and diffuse nebulae"" he applied the Doppler Principle to the measurement of the radial velocities of stars, and published an atlas of representative stellar spectra"" (Ripley: Source Book in Astronomy).
