Other analysts have obtained for the percentages of iron in taen- 
ite from other meteorites, values ranging from 86.44% to 57.18%, and 
corresponding to formulas varying from Fe, Nito Fe, Ni,. Judg- 
ing from our present knowledge of alloys it is hardly to be expected 
that taenite should have a uniform composition. Kamacite, being the 
substance with the lowest freezing point, is to be considered the 
eutectic of the series and as such has a fairly uniform composition, 
but this would not be expected of the other alloy or alloys.
