FIELDS OF THE BIOLOGY CODE 



Field A: Physical State of the Test Compound; Dispersion or Non- 

 dispersion of the Test Compound; Indication that In- 

 formation on Correlation of Chemical Structure and 

 Biological Response Occurs in the Information Source 22 



Field B: Conditioning Agent; Miscellaneous Information about the 

 Test Compound Administration; Indication that in the 

 Data Source there is Information on the Effect of pH 

 on the Chemical Action 23 



Field C: Solvent or Vehicle for the Test Compound 24 



Field D: Secondary Compound 25
