High-dispersion IUE spectroscopic observations of the B II resonance line at 1362.46 A are presented for six HgMn stars (kappa Cnc, ..mu.. Lep, 46 Draiola, CrB, HR 4072, and chi Lup), two magnetic peculiar stars (..cap alpha../sup 2/ CVn and HD 32633), and one normal B9.5 V star (..nu.. Cap). The B II line is present in great strength in kappa Cnc. It is absent from the five other HgMn stars. It is probably present, though unresolved and weak, in the magnetic stars. Its strength in ..nu.. Cap is consistent with a normal boron abundance.
