 Acid. 



[Oxyhydroparacumaric 

 acid.] 



OH

 after feeding with ty- 

 rosin.

 acute yellow atrophy of 

 the liver and phospho- 

 rus poisoning. 



Oxyphenylpropionie Acid 



[Hydroparacumaric acid.] 

 OH

 urine, decomposition 

 product of tyrosin. 

 When given to an ani-

 albumin, oxidised in the 

 organism to 



Benzoic acid.
