H2C {c 3 H 3 ' OH > and H2G {c2lL OH > for thQ normal l jri_ 

 mary alcohol are really identical, being but different condensa- 

 tions of the one formula, CH 2 (OH).CH 2 .CH 2 .CH 2 .CH 3 , but 



that the expressions HO.HCJ^g 7 , and HO.HCJ J^ 5 



for the normal secondary alcohol, and the expressions 



fC 2 H 4 .OH fC 2 H 5 



HC^CHs and HWCH 3 



(OH 3 (CH 2 .OH 



for the isoprimary alcohol are radically different, and appli- 

 cable in each case to a different compound. 



Taking the precaution to express in all cases the hydroxy lated 

 marsh-gas residue as a separate constituent of the alcohol, 

 Kolbe's system of nomenclature is quite in accordance with 

 the system of formulation for the paraffins and paraffin radicals 

 previously explained and exemplified. It seems preferable, 

 however, to restrict the application of the term carbinol in 

 great measure to the tertiary alcohols, to accord the term 

 pseudo-alcohol or pseudol to the secondary alcohols, and to 

 employ the term alcohol specifically to designate the alcohols 

 proper or primary alcohols, which, looked upon as hydrocar- 

 bon derivatives of the type XOH 2 (OH), may also be called 

 methols.
