A Semiotic Methodology for Animal Studies we shall not discuss the theoretical analysis of coupling here since this aspect has been treated elsewhere (W 29), and, rather than successively examining the coupling constants in given series of compounds, whe shall present the results in terms of the more or less quantitative correlations which have been discussed.
