7^3 = -002677 772 (calculated) = -003907, 
^3 = 75°-85 (from curve) = 34°-22, 
we obtain the formula 
_ 74-898 
” (146-621 + ’ 
which gives values which agree closely with those observed.

In reducing the observations we have used 0-91240 for the density at 0 °, and the 
expression 
Y = 1 -p -0.119971 t + -O 5 I 4867 t~ -f -0^0599 C 
fur the thermal expansion. 
Taking 
Pj = -006890 7/3 = -004254 772 (calculated) = -004254, 
h -0°*39 ^3 = 89°-69 fo (from curve) = 39°-38, 
we obtain the formula 
72-981 
It = 
(133-905 
which gives values in close concordance with those of observation.
