Of the fractions A and B 83 per cent, and of C 79 per cent, passes 
below 172° C., the residue above 200° C. is between 3*5 per cent., 
and the specific gravity of these fractions is U'859—0*804. It will be 
seen that A is the lightest, then comes B and then C. The acidity of 
A, B, C is only a trace. The fraction D on the other hand is abnor¬ 
mally heavy. Only 27 per cent, of D passes below 172° C. The 
specific gravity is greater being 0*883 and acidity is seven times that 
of A, B, C. If D is eliminated, the oil A, B, C will be much finer. 
So A, B, C were mixed and fractionated.

It will be seen that when A, B and C are mixed in equal propor¬ 
tions, a sample is obtained of which 75 per cent, passes below 172° C. 
and 82*5 per cent, below 180° C. A turpentine oil passing between 
160°—180° C. cannot but be regarded as quite above the average. 
Even if no redistillation is done, this sample might claim distinct 
preference over many of the market turpentines. 
II. 
The fractions A, B, C, D were thoroughly washed with water 
and the samples A 1? B x , C x , B 1 were made : — 
A x denotes first 10 bottles of a charge distilled under 
ordinary circumstances but shaken thoroughly with 
water. 
B, denotes second 10 bottles of a charge distilled under 
ordinary circumstances but shaken thoroughly with 
water. 
Cj denotes third 10 bottles of a charge distilled under 
ordinary circumstances but shaken thoroughly with 
water. 
Dj denotes balance (13 bottles) of a charge distilled under 
ordinary circumstances but shaken thoroughly with 
water.
