The acid was neutralized with ammonia and acetate of lead 
added. 0-2240 grm. of the lead 5 ar gave 0°1180 grm. 
‘sulphate of lead =36:21 pr. ct. lead. The formula C,,H,,;PbO,, 
- requires 36°42 p.c. The acid is therefore thenobaaia and has 
the following rational formula: (C,H;,0) CO. OH. The radi- 
cal requires one molecule of hydrogen i in order to become pho- 
ron, and an experiment with a small quantity, by heating with 
lime, made it apparent that this substance was produced as it 
is in like manner from some other camphor derivatives. I 
therefore name this body phoronylic acid. Phoronylic acid is 
isomeric with camphoric acid ; it is a syrupy fluid, not soluble 
in water, readily soluble in ether and alcohol, It has but slight 
odor, somewhat resembling cumarin. This odor is especially 
marked when the substance is heated with sulphuric acid and 
chromate of potassa. The alkaline salts of phoronylic acid are 
readily soluble in water and appear not to crystallize; the am- 
monia salt loses its area: on evaporation. The salts of the 
heavy metals are insolub 
The precipitate (A), isantionsd f in the foregoing, dissolved in 
alcohol, yielded on evaporation beautiful crystalline needles.
