The concentrations of B in seven carbonaceous chondritic meteorites have been determined by the use of two different analytical techniques. The data correspond to a B/H ratio of about 10/sup -9/ compared to the value of 10/sup -8/ previously proposed by Cameron, Colgate, and Grossman. However, the meteoritic abundance remains at least a factor of 2--10 higher than various estimates of the solar photosphere abundance. We conclude that both meteoritic and photospheric B and Be abundances must be considered in comparisons with nucleosynthesis calculations. Using our revised B abundances and assuming /sup 7/Li was synthesized in the big bang, we find that the residual /sup 6/Li//sup 10/B, /sup 9/Be//sup 10/B, and /sup 11/B//sup 10/B abundance ratios are well matched by the production rates for bombardment of a CNO mixture of solar proportions by protons and ..cap alpha..-particles with a kinetic energy per necleon spectrum of the form E/sup -1//sup .//sup 8/.
