(6) Such titles which embrace euphonic combinations of different syl- 

 lables of the names of bodies entering into the composition of the remedy, 

 for example, Tann-albin (a compound of tannin and albumen), Amylo- 

 form (combination of starch and formaldehyde), Sali-pyri?ie (a compound 

 of salicylic acid and antipyrine, etc.). 



Class II. Descriptive Titles. 



These are specially coined euphonic titles usually of Greek or Latin 

 origin and partake of a descriptive character. These titles describe in a 

 way either the uses, properties or physical characters of the compound, as 

 for example, Pyoktanin is made up of the Greek words vuoN=pus, and 

 kteino = to kill; Thalline from the Greek Thallos meaning a green twig, 

 in allusion to the bright green color produced by the action of oxidizing 

 agents. Loretin, the valuable antiseptic, a derivative of quinolin, is an 

 adaption from Laura, being an arbitrary title. A selection made from a few 

 of the various classes are cited as follows : 



Class I. Aldehydes. 



Formalin (Formol or Formatol). Aqueous solution of formaldehyde. 



Formo-pyrine A compound of formaldehyde and antipyrine. 



Colla-form (Formacoll) (kolla =glue). A dry compound of formalde- 

 hyde and gelatin. 



Amylo-form (amylum = starch). A condensation product of starch 

 and formaldehyde. 



Chino-form. A condensation product of cincho-tannic acid and for- 

 maldehyde, etc., etc. 

 Class II. is not represented. 



Class I. Amides. 



Formamide. The amide of formic acid H.CO.NH 2 . 



Thiosinamine. An allyl-sulfo-urea (theion = sulfur + sinamoreo = 

 to destroy). This chemical title refers to the antiseptic properties of a sulfur 

 compound. 



Methoxy- also Ethoxy-caffeine. 



Urea— NH 2 — CO— NH 2 . 

 Class II. 



Somnal (somnus = sleep). A chloral urethrane alcoholate. 



Symphorol (probably from syn = together + PHERO = to carry off). 



Amido-Phenol Derivatives. 

 The following synthetics are derivates of para-phenetidin (C 6 H 4 - 

 (NH 2 )(OC 2 H 5 )), in which one or both hydrogens of the amido group 

 (NH 2 ) are replaced by various organic acid residues. The introduction 

 of such acid residues materially lessens the toxic antipyretic properties of 

 phenetidin.
