Activation analysis was used to determine the bromine content of eleven stony meteorites. The values found by this method are appreciably lower than those obtained up to now by conventional chemical analysis. The highest value found is 1.56 ppm and the lowest 35 ppb. Hot water leaches removed considerable amounts of bromine in two samples tested (31 and 88 per cent respectively). The bromine to chlorine ratio in the leach water is essentially the same as in the meteorite; this seems to exclude the possibility of surface contamination of the samples. The ratio of chlorine to bromine content in eleven meteorites varies over two orders of magnitude and depends on the absolute chlorine content. Within the limits of accuracy of the method used, the isotopic composition of bromine in the 5 samples tested seems to be the same as in the case of terrestrial bromine.
