Cy, Hy2N.0 Dimethyloxyquinazine = Antipyrine. 
Thermifugin is another of these compounds. Hypnal is a com- 
pound of antipyrine with chloral. Salipyrine is a compound of 
antipyrine and salicylic acid. Iodol, a substitute for iodoform, is a 
pyrrol compound, one of the cousins of chinoline and pyridine. 
The wonderful results obtained in the use of the chinoline and 
pyridine compounds stimulated experiments on other organic bodies 
made in the chemical laboratory by building up or synthesis. 
I can only mention some of these by name. Among hypnoties 
and anesthetics we have— 
Methylal. Urethane. 
Amylene hydrate. d Sulphonal. 
Para aldehyde. Di and tri chlor methane. 
Then we have a series of antiseptics allied to carbolic acid. These 
include— 
Alpha-naphthol from naphthalene. Beta-naphthyl salicylate or Betol. 
Beta- '‘° . ts Aseptol-orthophenol sulphonie acid. 
Tribromphenol or bromol. Sozoiodoi-diiodophenolsulphonate. 
Phenyl salicylate or salol. 
Another series includes bodies allied to aniline, the substance that 
gives the well-known colors— 
Antifebrine or acetanilide. Pyrodine. 
Phenacetine. Autithermine.
