Abstract
III. IN the year 1890 a photographic study of the spectra of stars was commenced by me at the Solar Physics Observatory at Kensington. The object of the investigation was not so much to make a spectroscopic survey of the stars generally as to examine with considerable dispersion the spectra of the brighter individual stars. Up to the end of the year 1900 there had been accumulated a large number of spectra, a catalogue of which was published in the year 1902. This contained 470 of the brighter stars.
