In reducing the observations we have employed the value 1’52637 for the density 
at 0 °, and the expression 
V = 1 + -03123024^ + -05171383^2 + -088338^'^ 
for the thermal expansion (Thorpe, loc. cit.). 
Taking 
7 ^^ = -006979 7/3 = -004006 773 (calculated) = -005288 
= 0°-33 ^3 = 56°-94 t.^ (from curve) = 26^-48, 
we obtain the formula 
70-4244 
~ (158-33 + ’ 
which gives results in very good agreement with those obtained by observation.
