The abundances of 27 elements are reported for the Murchison meteorite. Nine of these elements (Al, Ca, Fe, Mn, Na, K, Cr, Co, and Sc) have been determined previously for different Murchison specimens. Abundances for 18 elements (In, Cd, V, Y, and REE) are new data for this meteorite. The chemical composition is similar to the type II carbonaceous chondrites, particularly on the basis of REE, Mn, and In abundances.
