Mustard Oil, artificial. The manufacture of this oil has now 
for some time been carried on regularly at our Works. Our plant is 
fully employed for important orders from Europe and America. The 
entirely new process used by us enables us to meet all competition, 
and every consumer who has asked us for special quotations has had 
an opportunity of satisfying himself on this point. 
Neroli Oil (oil of bitter Orange-blossoms). As in previous 
years, Mr. JeanGras of Cannes has again supplied us a table 
showing the results of his distillation this year, and the properties of 
the oils thereby obtained. We reproduce here this table:
