The abundances of the elements Cl, F, P, Mn, Ti, Zn, Ge, Co, Ni, Fe, V, Cu, Sr, Cr, Ba and Sc have been determined in a total of fifty meteorites involving representatives of all chondrite groups. These analyses are discussed in terms of the observed co-variations among the various elements and the chemical fractionation which distinguishes the individual chondrite groups from each other. The results indicate: 1. (1) The trace elements Cu, Zn, Ge and Cl are fractionated among the carbonaceous, enstatite and ordinary chondrites similar to the so-called "fractionated chalcophile" elements; 2. (2) A fractionation of silicate plus sulphide phase from metal phase within both the bronzite and hypersthene chondrite groups; 3. (3) Prior's Rule is not strictly valid in any of the chondrite groups; 4. (4) A fractionation of cobalt from nickel such that the metal-rich chondrites in both the hypersthene and bronzite groups are enriched in cobalt relative to nickel; 5. (5) The chemical differences between the hypersthene and bronzite chondrite groups can be attributed almost entirely to a relatively minor transfer of cobalt-rich metal from the hypersthene to the bronzite chondritess followed by further reduction.
