 Thiocamph (thi'-o-kamf) [deiov, sulphur, eamphor]. A 

 fluid disinfectant, used for fumigation. It is formed by 

 the action of sulphurous acid on camphor and is used 

 in the strength of one ounce to a pint or quart. Unof.

 occurs in two forms, the dry and the liquid. It has 



sulphur for oxy-

 superior to iodoform. Unof. T., diiodid, has been 

 recommended as an antiseptic.

 a faint, agreeable, aromatic odor.
