The spiral structure of our Galaxy, as defined by optical evidence, shows a striking gap around lII = 270°. Intrigued by this feature, the author started, in 1955, a survey of early type stars based on objective-prism plates taken with the ADH-Schmidttelescope of the Boyden Observatory (South-Africa); dispersion of the spectra: 240 Å/mm at Hγ.
