Experiments are described which have clarified the chemistry of the D.N.P. * method 1 for pyrethrum and allethrin assay. The fate during the course of analysis of a number of the non‐insecticidal contaminants has been determined and the scope and limitations of the method are reviewed in the light of the new findings.
