In reducing the observations, we have used d[0'j^°) = 0‘92005 for the density, 
and the expression 
V = 1 + -O.l 13062 t + -0324809 + ‘0336230 td 
for the thermal expansion. 
Taking 
yi = ‘007551 
7^3 = ‘002597 
770 (calculated) = ‘004428, 
^3 - 98°‘03 
t .2 (from curve) = 42'’-13, 
the formula 
5:3-0991 
“ (12:3-745 + 
IS obtained, which satisfactorily reproduces the observed values.
