Scientific paper

Objective prism and photometric data on about 8000 stars of common photometric type and 158 OB stars are used to derive the space density, at various distances, of stars in several spectral-type groupings. At a distance of about 350 parsecs, a pronounced maximum is noted in the numbers of B8-A1 stars and G-K giants. Indications are also found of a maximum in the OB star distribution at a distance of the order of 2500 kpc. There is a sharp decrease in the numbers of later-type dwarfs with increasing distance from the sun, although the data in question are only reliable for a few hundred parsecs.
