Part I.] Puran Singh : Turpentine Oil and Indian Rosin. 
The results of the examination show that there is little differ¬ 
ence in composition between the Indian colophony and that pro¬ 
cured from the United States and France. The Indian sample (a) 
from Naini Tal was rather dark in colour, and for that reason 
would rank as of low grade, but there appears to be no reason why, 
if reasonable care is exercised in the collection of the crude turpen¬ 
tine and in its distillation, a pale-yellow rosin should not be pro¬ 
duced in India. 
Commercial Valuation of Indian Colophony. 
Samples of the first three rosins, viz., ( a ), ( b ) and (c) referred 
to above, were submitted to rosin importers and to soap-manufac¬ 
turers, for valuation and trial. The former reported that ( a ) would 
be worth £7 per ton, ( b) £8 per ton, and (c) £12 per ton. The 
soap-makers stated that (a) and ( 6 ) would be too dark for their pur¬ 
poses, but might be suitable for use in paper manufacture and for 
that purpose would be worth from £9 65 . to £10 per ton, whilst 
(c) would be suitable for soap-making and worth £11 per ton in 
this country. * * *
