Abstract
Using ATLAS9 model atmospheres and additional spectroscopic data from the Kitt Peak coude-feed telescope obtained with a 3000-pixel-long CCD , camera 5, and grating A, we extend fine analyses of the B and A star s, gamma Gem, HD 60825 and 7 Sex. In addition, we study two moderately sharp-lined middle B stars, HR 1397 and 2154, whose elemental abundan ces we find to be generally within the range of values seen for superf icially normal, main-sequence stars of similar temperatures.
