spars may well have identical geometrical structures; the valence relations in solution merely require the one replacement to be accompanied by the other, and do not persist into the solid form of the compounds. Orthoclase and carnegieite can not be isomorphous with anorthite because the potassium atom of the one, and still more the two sodium atoms of the other, demand more space than displacement of the calcium can furnish. The simplest formulas adapted to bring out all the relations are: Albite, NaAI-(Si308) ; anorthite CaAl(A1Si2Os).
