Abstract
CLOUDY and hazy nights have seriously interfered with spectroscopic observations of this nova at Stony-hurst, but some good photographs of the spectrum were obtained with the Whitelow short-focus prismatic camera on the nights of August 29 and 30 and September 6 by Father J. Rowland. The spectrum, the bright band spectrum characteristic of the second stage in the progressive spectra of novæ, remained practically the same during that interval. The bright hydrogen bands extended, on the average, over 20 Å. units, and consisted each of two components. There was a bright extension on the violet edge of Hζ about λ3870, which was possibly the first sign of the incoming of the nebular band.
