A mineralogical and chemical analysis has been performed on a slice of the Mills, New Mexico, chondrite, which was found in August 1970. The mineralogical composition is olivine Fa 19.5 , bronzite , Fs 17.4 , plagioclase, nickel‐iron, troilite and ilmenite. The chemical analysis confirms that Mills is a typical bronzite, H5 chondrite, with considerable degree of weathering, as indicated by the presence of large amounts of Fe 2 O 3 . A comparison with other stones found in the same New Mexico region by Nininger may show a possible relation between Mills and previous finds.
