Compounds related to the first body only of this series will be noted : 



The Hydride of phenyl, C 6 H 6 , earolel, is formed on the monad type. 



Chloride of phenyl or Monochloride of benzene, is ear o laid ; and 



Bromide of phenyl or Monobromide of benzene, earolalb. 



The Hydrate of phenyl, better known as Carbolic or Phenic acid, sometimes called 

 Phenic alcohol and Phenol, has the empirical name of earlat. As an alcohol, its 

 new name would be earolelat ; as an acid, learolalt. Its relation with aniline will 

 be recognized by the empirical name of aniline (as well as of picodine), eareelan, 

 the typical name being earolilan ; or if the radical is expressed in two syllables, 

 earulelan, i.e. Monophylamine ; thus Triphenylamine is expressed by earuliman. 



In the following table are embraced the known dyad homologues of the 

 carbonic-acid and the oxalic-acid series, formed by the increment ach : 



The substitution of a dyad metal, or two atoms of a monad metal, for el in 

 this series, will form the corresponding metallic salts. 



In a similar manner may be classified alkaloids ; for instance, those obtained 

 by dry distillation of animal matter : 



Pyridine, 

 Picoline, j 

 Lutidine, 

 Collidine, 

 Pavoline, 



6 H 5 N, urlan. 



C 6 H 7 N = CH 2 C 5 H 5 N, achurlan. 



C 7 H 8 N == (CH 2 ) 2 5 H 5 N, echurlan. 



8 H 9 N = (CH 2 ) S C 6 H 5 N, ichurlan. 



C 9 HioN = (CH 2 ) 4 C 5 H 6 N, ochurlan. 



Substitutions. DUMAS s doctrine of substitutions is very clearly set forth 

 in the following examples 



1. Marsh gas = arol. Chloride of methyl (achald) = arildd. 

 Monochlorinated chloride of methyl, areled. 

 Dichlorinated chloride of methyl (chloroform), arlid. 

 Perchlorinated chloride of methyl, arod. 



2. Ethylene, erlel. Chlorinated ethylene, erlald. 

 Dichlorinated ethylene, C 2 H 2 C1 2 , erled. 

 Trichlorinated ethylene, C 2 HC1 3 , eralid. 

 Perchlorinated ethylene, C 2 C1 4 , erod. 



3. The action of chlorine on ethylene and chloride of ethyl produces metameric 



compounds having widely different boiling points, thus distinguished : 



Bichloride of ethylene (Dutch liquid), 

 Monochloretted chloride of ethyl, 

 Monochlorinated ethylene, 

 Dichlorinated chloride of ethyl, 

 Dichlorinated ethylene, 

 Trichlorinated chloride of ethyl, 

 Trichlorinated ethylene. 

 Tetrachlorinated chloride of ethyl, 

 Perchlorinated ethylene,
