In reducing the observations we have used the value 0’8832 for the density at 0°, 
and for the thermal expansion the expression 
V = 1 + -0386172 t + -0525344 — -0818319 
given by Weger (‘ Annalen,’ voL 221, p. 67). 
On plotting the above values the coefficients (H.) contained in the third column of 
the following table were obtained. The second column gives the coefficients (I.) 
found from the original sample of ethyl benzene, and the diffei'ences between the two 
series of values are given in the last column.

At low temperatures the values are identical, and at high temperatures the new 
sample gives coefficients which are the lower by about 0-4 per cent, Between 30°
