Dose n\j-iij . Beechwood Creasote, from Fagussyl- 

 z-atica, is best for internal use. Dose mj, every three 

 hours. C, Aqua, a one per cent, solution. Dose 

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

 Dose % j-ij. C.-oil, Heavy Oil, the third main frac- 

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

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

 anthracene commences to distil. The oil has a green- 

 ish-vellow 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 

 mainly in the creasoting or preservation of timber ; 

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

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

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

 on. C, Vapor ^B.P.), for inhalation,

 ith one molecule of water in glistening prisms, which, 

 heated to ioo°, sustain a loss of water. It has a faintly 

 iter taste and dissolves rather readily in boiling water, 

 dissolves with difficulty in alcohol and yields crys- 

 line salts with one equivalent of acid. 

 Creatinin kre-af '-in-iti) [Kpiac, flesh], C 4 H-X 3 0. An 

 dine substance, a normal constituent of urine. It 

 crystallizes in rhombic prisms, and is a strong base.
