Kaolin is contained in Cataplasina Kaolini (q. v.). It is used in 
dusting powders; also in pills containing easiW reduced bodies, such 
as silver nitrate or potassium permanganate, which can not be mixed 
with ordinary excipients. 
LIQUOR ANTISEPTICUS. 
Antiseptic Solution. 
A solution of mild aromatics and antiseptics similar to certain com- 
mercial preparations. Among other things it contains about 2 per 
cent of boric acid, 0.1 per cent each of benzoic acid and thymol, and 
25 per cent of alcohol. 
Dose. — ‘^Average dose: 4 Cc. (1 tiuidrachm).” (U. S. P.) 
LIQUOR CHLORI COMPOSITUS. 
Compound Solution of Chlorine. 
Clilorine Water. 
This takes the place of Aqua Chlori (U. S. P., 1890). The method of 
preparation (for which see the Pharmacopoeia) is materially changed 
and simplified. When freshh^ prepared it contains about 0.4 per cent 
of chlorine with some oxides of chlorine and potassium chloride. 
Dose. — “Average dose: 4 Cc. (1 tiuidrachm).” (U. S. P.) 
LIQUOR CRESOLIS COMPOSITUS. 
Compound Solution of Cresol. 
Liquor Cresoli saponatus is the official German title of a somewhat 
similar preparation. It is essentially a linseed-oil-soap solution of 
cresol, of 50 per cent strength; the soap dissolves the cresol as do 
alkalies. This is a mixture of much more definite composition than 
many commercial preparations of similar nature. 
For practical use the 50 per cent solution is diluted with water to 
various degrees according to need. 
Other preparations of this nature are known as creolin^ disinfectol^ 
enter OCT esol^ germol^ cresolin^ lysol^ h/sitol, etc. (See Cresol). 
LIQUOR FORMALDEHYDI. 
Solution of Formaldehyde. 
An aqueous solution containing not less than 37 per cent by weight 
of absolute Formaldehyde (H.COH); an assay process is provided. 
Official in the German Pharmacopoeia as Formaldehydum solutum and 
variousl}" known as formalin^ fc/nnol^ methylaldehyde^ oxy methylene^ 
methanol^ etc. 
Properties. — Formaldehyde itself is a gas at ordinary temperatures 
having a very pungent odor. The various products on the market are 
solutions of the gas in water. Formaldehyde readily undergoes a
