In the reduction of the observations we have employed Zander’s value, 0‘8233, for 
the density at 0°, and his expression 
V = 1 + - 0383751 ^ + -0528634^2 - •08l2415^3 
for the thermal expansion (‘ Annalen,’ 224, 80). 
Two formulse are required to reproduce the values with sufficient accuracy. The 
first extends from 0° to 52°, the second from 52° to 114°. 
They are respectively as follows :— 
65187500-0 __ 117255-0 
~ (139-05 + ~~ (91-997 + ’ 
The agreement between the observed and calculated values is seen in the following
