MESSRS. T. E. THORPE AND J. W. RODGER ON THE RELATIONS 
Carbon Tetrachloride. CCI4,. 
The sample employed for our observations was obtained by repeatedly agitating a 
(Quantity of the rectified liquid with potash solution, decanting, drying over phosphoric 
oxide, and fractionating. The liquid was eventually found to boil constantly at 
76°*76. Bar. 755*4 millims. Corrected and reduced b.p. = 76°*96. 
Vapour density : 
Found, 76*62. Calculated, 76*74.

In reducing the observations we have adopted the value = 1*63195 for the 
density, and the expression 
V = 1 + * 0 . 3120719 ^ + *0667109^® + *07l3478/!3 
for the thermal expansion (Thorpe, loc. cit.). 
Taking 
-013322 7^3 =*005017 
q = 0°*60 ^3 = 74°*16 
we obtain the expression 
32-780 
~ (95-05 + ’ 
which gives the following calculated values :— 
173 (calculated) = *008175 
(from curve) = 32° 17,
