In reducing the observations we have employed the value d(0°/0°) = 2’334G for 
the relative density, and the expression 
V = 1 + + •0540465^2 - - 0727393 ^^ 
for the thermal expansion (Dobriner, ‘ Annalen,’ 243, 23). 
Taking 
-171 = ‘005914 773 = ‘004090 77 ^ (calculated) = ‘004918 
h = 0°‘42 tg = 39°‘96 (from curve) = 18°‘92, 
we obtain the formula 
_ 6 ' 6.777 
~ (13U32TT)™ ’ 
which almost exactly expresses the observed values.
