  We report on extreme-ultraviolet (EUV) spectroscopic observations of the B
bright giant epsilon Canis Majoris made during the ORFEUS-SPAS II mission. We
assess the performance of the instrument in the EUV and find that the effective
area is roughly 3 times that of the Extreme-Ultraviolet Explorer (EUVE)
long-wavelength spectrometer and that the spectral resolution is
lambda/Delta(lambda) = 1250. We identify most of the features, qualitatively
compare different models, and examine the wind-broadened O V and Si IV lines,
which display blue edge velocities up to 800 km/s.
