In reducing the observations we have adopted the value d (074°) = 0’8335 for the 
density, and the expression 
V = 1 + -0.3115342^ -b -05188396^3+ -0832021^3 
for the thermal expansion (Thorpe and L. M. Jones, Joe cit.). 
Taking 
= -005914 ^73 = -002279 % (calculated) = -003G71 
= 0°-46 ^3 = 98°-82 (from curve) 43°-38, 
we obtain the formula 
64-487 
~ (146-67 + ’ 
which gives the following calculated values
