 lapellus. It is an anodyne and antineuralgic. Dose, 

 7. i-J. See Aconite.

Aphtha (naf'-thah) [vaofta, asphaltum]. Danforth's 

 I 'il ; a product obtained from petroleum, boiling at 8o° 

 a Ilo° C. ; specific gravity .690 to .700 or 76 to 70 

 ». It is used for burning in vapor-stoves and street- 

 unps, as a solvent for resins in making varnishes, and 

 ' i the manufacture of oilcloths. 



i phthalene inaf'-thal-en) [vacjtta, asphaltum], C 10 H 8 . 

 >ne of the principal constituents of coal-tar, occurring 

 i it in various proportions of from five to ten per cent. ; 

 is also formed when the vapors of organic substances 

 re passed through tubes heated to redness. The 

 oecific gravity of naphthalene when solid is 1.158 ; at 

 l melting point (79. 2° C. )the specific gravity is 0.978 ; 





it boils at 216. 6° C. The odor is pleasant, though char- 

 acteristic: Naphthalene crystallizes in large, silvery, 

 brilliant, thin, rhombic plates, that are feebly soluble in 

 hot, but insoluble in cold water, though easily soluble 

 in methyl and ethyl alcohols, chloroform, ether, and 

 benzene. It is employed in the manufacture of a large 

 series of coloring-matters ; as an enricher of illuminat- 

 ing gas ; and when specially refined, as a substitute for 

 ordinary camphor in preventing the ravages of insects 

 in woollen goods. It is an antiseptic, and, internally, 

 an active expectorant ; it is useful as a dressing for indo- 

 lent sores, and, internally, in pulmonary catarrh. Dose, 

 gr. ij-x in emulsion, or in pill, gr. 2, given every hour. 

 In large doses it is toxic, causing emesis and purgation.

 spectus of. N.-red, N. -scarlet, N. -violet. See 

 Pigments, Conspectus of.

 hypothetic substance existing in many naphthalin 

 compounds. The naphthenes are hydrocarbons present 

 in German oils, and are also contained in Caucasian 

 petroleum ; they are insoluble in sulphuric acid ; octo- 

 naphthene, C g H, 6 , and nono-naphthene, C 9 H,„, are 

 well known ; the naphthenes are considered identical 

 with the benzene hexa-hydrids. 



Naphthylamin (nafthil ' -amin). Same as Naphthal- 

 idin .

 nym of Xaphthene. N.-blue. See Pigments, Con- 

 spectus of. 



Naphthylurea (nafthil-u' '-re-ah) (raoda, asphaltum: 

 ovpw, urine]. A substance that appears in the urine 

 after free administration of naphthalin ; it colors the 

 excretion brown. With acetic acid it gives a rose 

 color; with sulphuric acid it has a green reaction. 



Naphtol, or Alpha-naphtol (naf / -tol) \yaoda, as- 

 phaltum], C^H^OH. A substance that results from 

 a-naphthylamin by means of the diazo-compound. It 

 is soluble with difficulty in hot water, readily in al- 

 cohol and ether, erystallizes in shining needles, and 

 has the odor of phenol. It melts at 95 C. , and boils 

 at 278°-28o° C. It is used in the preparation of alpha- 

 oxynaphtoic acid. N., /3-, or Beta-naphtol, 

 C 10 H..OH, is formed from ,3-naphthylamin. It is 

 readily soluble in hot water : it crystallizes in leaflets, 

 melting at 122 C, and boiling at 286 C. N.-blue. 

 See Pigments, Conspectus of. N. -camphor, a mix- 

 ture of J-naphtol one part, with camphor two parts. 

 It is antiseptic, and is used in diphtheria and pulmon- 

 ary tuberculosis. Unof. N. -green, N. -violet, N.- 

 yellow. See Pigments, Conspectus of.
