Abstract : The purposes of the investigations have been the following: (a) To conduct a search of the northern Milky Way for intrinsically luminous stars of early spectral type, to fainter apparent magnitudes than hitherto achieved systematically, (b) pursuant to point (a), to check and, if possible, improve existing methods of classifying lowdispersion stellar spectra on objective-prism plates, (c) to test whether any gross features of galactic structure may be determined from the raw material of (a), and (d) to utilize the objective prism plates secured for part (a) for the identification of other spectra of unusual interest falling in the survey area.
