Chromium, cobalt and strontium in some Bureau of

CHROMIUM AND COBALT Chromium has been determined in stone meteorites by BATE et al. (1960) using a neutron activation technique similar in many respects to the method to be de- scribed. These authors, however, were not searching simultaneously for cobalt or the alkalis as we were, hence our analytical procedures are somewhat different.
