The electron-probe microanalyser was used to obtain Ni analyses of separate phases in nine metallic and one stony meteorite. Proper surface preparation and adequate calibration were found to be important. Kamacite composition was uniform throughout the phase. In swathing kamacite, however, Ni became appreciably lower near a schreibersite inclusion. Taenite exhibited a marked composition gradient which increased at the taenite-kamacite interface. The Ni content of fine plessite was intermediate. It also exhibited a Ni concentration gradient, which was continuous with that of adjacent taenite. There facts accord with cooling of the original meteorite body or bodies over a long period of time to a temperature of 300°C or lower. The time was short of that required to produce uniform composition taenite, or uniform composition kamacite near schreibersite inclusions.
