A warm welcome must be given to this first photometric atlas of stellar spectra, a useful reminder of the increased importance attached to the quantitative study of stellar radiation. Eight bright stars ranging from B8 to M2 have been photo graphed with the Coudé spectrograph of the 82-inch reflector of the McDonald Observatory, Texas University. The dispersion varies from 2.1 A. per mm. at 4000 A. to 14.2 A. per mm. at λ 6500 A. The spectra have been analysed at the University of Michigan with a null-type direct-intensity micro-photometer. The resultant tracings with the intensity scale are reproduced for each star in a set of some sixty sections ranging from 20 A. at λ 4000 A. to 100 A. at 6600 A.; the magnification from spectro gram to published tracing is 21.6.
