    Notes: [Auszug] One of us (C. G.

This produces a marked difference in the curves for normal and irradiated polythene ...

Thus, in the pea test, only 2 : 4-di-chlorophenoxyacetonitrile (n = 1) was active and this correlated with the production of the corresponding acid. No activity was shown in the pea test by any of the higher homologues, and this ...
