The liquid was quite colourless to begin with, but in the course of the observations 
it became tinted, and at the close was of the colour of pale sherry. 
In reducing the observations we have employed the value d{0°/0°) = 17440 for 
the relative density, and the relative volumes given by F. D. Brown (‘ Boy. Soc. 
Proc.,’ 36, 245) for the thermal expansion. 
Taking 
7 }^ = -008749 7)^ = -003606 >73 (calculated) = -005617 
q = 0°-30 q = 88°-72 q (from curve) = 39°-42, 
we obtain 
129-85 
~ (150-03 + ’ 
which gives values in good agreement with those obtained by observation.
