ResumoCrystal Structure of Calcium.---The X-ray pattern obtained with powdered calcium shows that the atoms are arranged in a face-centered cubic lattice. The side of the elementary cube is 5.56 \AA{}. The Ca atoms in Ca have therefore the same arrangement as in CaO and Ca${\mathrm{F}}_{2}$; but in the fluoride and oxide the atoms are respectively 2 and 14 per cent. closer together than without the fluorine and oxygen.
