In the Laboratory A, B, C, I) were now mixed to examine the 
quality of the mixture, which on fractional distillation gave the 
following results: —

Here we may appropriately give the results of the examination 
of the original oil as manufactured at Bhowali: — 
A 4 denotes the present Bhowali turpentine but shaken with 
water. 
B 4 denotes the present Bhowali turpentine.

It will be seen that A + B + C + H is better than A 4 and B 4 . Only 
60 per cent, of A 4 passes below 172° C., while of A + B + C + D 67 
per cent, passes below that temperature- The residue of the latter 
is only 10 per cent, while of the former is 14—18 per cent.
