Quality of Linseed Oil of India.—It may appear remarkable 
that Linseed Oil should be imported into Calcutta, when so 
much Linseed is exported for the express purpose of yielding its 
oil. This is in consequence of the Linseed Oil of India being 
considered as not possessed of the full drying properties of the 
oil prepared in Europe. But there is no doubt, this is owing 
entirely to the Indian Linseed being expressed before the Mus- 
tard seed has been separated, with which it is commonly mixed, 
in consequence of the two plants being often grown together. 
Mr. Bowen informed the Author that, when connected with one 
of the lighthouses in India, he had at one time under his charge 
some plate glass. This he made use of to separate the two 
seeds, by placing it on a slope: the round seeds of the Mustard 
rolled off, while the Linseed merely slipped down. These, when 
expressed, yielded as good drying oil as any he ever obtained 
from Europe. The same fact is confirmed by the following 
statements. 
In a report from Mr. W. Ewin, Branch Pilot, to Capt. W. 
Hope, Master-Attendant at Calcutta, he acknowledges the re-
