light red oil began to go down. By treating the mother 
liquor as in the case of the chlorine compounds two oils 
were obtained; one of a light red color and perfectly 
clear, the other dark red and much more consistent. 
It is quite difficult to get these oils pure and un¬ 
mixed. The color of the oil, which is first precipitated, 
must be closely observed, and when this changes, a 
mixture has taken place. 
FIRST BROMINE COMBINATION.
