In that constellation, as we see, we meet with pyridine, in contra- 
distinction to nitrobenzol in my case. If we leave this element, which 
is different, aside and if we take into consideration only what they 
have in common, we are in a position, in both my odour-system 
and that of Hermanides, to put two groups of odours over against 
one another. 
Grou P A - Group B. 
isoamylacetate valerian acid 
terpineol sca(o l 
guajacol 
In these two groups terpineol and guajacol, on the ground of the 
reciprocity mentioned just now, stand in the same proportion to 
each other as valerian acid and scatol. 
Cases of odour-compensations, showing both for Z and Hs 
about the same proportions.
