 hours. C., Aqua, a one percent, solution. Dose 

 Sj-iv. C.-bath. See Bath. C, Mistura (B.P.). 

 Dose J5J-ij. C.-oil, Heavy Oil, the third mam frac- 

 tion in the coal tar distillation-process. It is collected 

 at temperatures of from 230 to 270° C, or until the 

 anthracene commence- to distil. The oil has a green- 

 ish-yellow color, and is very fluorescent, and becomes 

 progressively more so upon exposure to light and air. 

 The odor is unpleasant and extremely characteristic. 

 The oil is heavier than water, and contains naphthalene, 

 anthracene, phenanthrene, phenol, cresol, etc. It is 

 used mainly in the creasoting or preservation of timber ; 

 it is also used as a fuel, and for the production ol illu- 

 minating nas, as a lubricant, and for the production of 

 lampblack. C, Unguentum \ B.P.), for local appli-
