The radiochemical procedures for the assay of bismuth, thallium, and mercury in stone meteorites following neutron activation are described in detail. A Bi 209 abundance of 2.2 sx 10 -9 gramme/ gramme meteorite leading to a cosmic abundance of 0.0016 (per 10 6 Si atoms) was determined from the analysis of six stone meteorites. A T1 209 abundance of 0.40 sx 10 -9 g/g meteorite and a Hg 202 abundance of 30 sx 10 -9 g/g meteorite corresponding to cosmic abundances of 0.00030 and 0.023 (per 10 6 Si atoms), respectively, were determined from analysis of five stone meteorites. Implications of these data as pertaining to the life history of meteorites are discussed.
