Scientific paper

Limits to the line-of-sight column density of B II towards early-type stars are used to obtain limits to the abundance of boron in H II regions. The relevant analysis is outlined and applied to the observations of Zeta Oph and Lambda Ori to derive limits to the boron abundance which are lower than those obtained from measurements of carbonaceous chondrites. It is suggested that further valuable limits to the abundance of boron may be obtained by searching for the 1362-A line of B II towards unreddened stars of spectral type around O9.5. It is noted that similar results can come from searches for the 2066-A and 2067-A lines of B III towards stars of earlier spectral types.
