group, and thus its formula is represented by CoH7OH

Physical Properties. Iso-naphthol is a brilliant crys-
talline body having an odor resembling that of phenic
acid and a slight burning taste. Its melting-point is
253.4 F. (123 C.), and it boils at 546.8 F. (286 C.).
A solution in water gives a bluish-violet fluorescence on
the addition of ammonia or soda. Ferric chloride ex-
hibits a green tint by which it is distinguished from
alpha-naphtliol, which gives a violet color with the
same reagent.
Solubility.-Beta-naphthol is readily soluble in al-
cohol, ether, chloroform, benzene, and the fatty oils; it is
almost insoluble in cold water, but fairly so in hot water.
Therapeutic Applications.-Naphthol is much used
as a general antiseptic in cutaneous disorders, organic or
parasitic, and in affections of the respiratory tract. It
has been of service in the treatment of chronic middle-
ear disease, and as an intestinal antiseptic in typhoid and
typhus fevers and in chronic diarrhoeas. This remedy
has bactericidal powers. It has of late been found service-
able as a vermifuge in cases of ascarides.
Administration.-The internal dose of naphthol varies
from 2 to 15 grains (o.12 to I gramme). Externally,
alcoholic solutions of the strength of from 2 to 10 per
cent., or ointments of the strength varying from 3 to io
per cent., are employed.'
I There are other allied compounds and derivatives of naphthol, chief
among which may be mentioned naphthol-aristol or di-iod-beta-naphthol,
a mixture of iodine, iodide of potassium, beta-naphthol, and carbonate and
hypochloride of sodium; nap/thol-camphor; naph/topyrin, a combination
of naphthol and antipyrin; alpza-naphthol; alpha-oxynaphoic acid; and
others already described under various names. Most of these derivatives
and compounds have been used for the same purpose as beta-naphthol itself.
The most recent combination is the beta-nazp/hol-bismuth, which is said to
contain 80o per cent. of the oxide of bismuth. This compound is recom-
mended as an excellent intestinal antiseptic. It occurs in the form of a
neutral brown odorless powder, insoluble in water. It is decomposed in the
intestines into its component parts, the bismuth being eliminated by the
stools, the beta-naphthol by the urine. The dose of the drug is put down
as from 15 to 30 grains (I to 2 grammes). (See p. 52.)I39
