High-resolution Reticon spectra of seven reputedly normal B9.5 - A2 V stars with v sin i < 50 km s-1 were recorded using the ESO Coudé Echelle Spectrometer. A selection of these spectra is presented here: two wavelength bands containing lines of He, C, Mg, the iron group, and Ba. Significant abundance variations from star to star are indicated for carbon and, apparently uncorrelated with C, for the heavier elements. One of the stars, HR 3383 (A1 V), has very sharp lines.
