In the reduction of the observations the value for the density d ( 0 '^/ 4 °) = 0 ’ 70048 , 
and the expression for the thermal expansion 
V = 1 + *00121023^ + + -0.1174^3, 
already given by one of us (Thorpe, loc. cit.), have been employed. 
Taking 
rj^ = -004797 7^3 = -002096 (calculated) = '003171 
= 6°'43 
^3 = 92°'22 ^2 curve) = 45°'28, 
we obtain 
445-9^ 
Vi = 
(180-14 + Q3-1879 
which gives numbers in good agreement with the observed values.
