A number of partial methyl ethers of hydroxy flavones and related compounds have been tested for toxicity to fish and the results are discussed with reference to structural characteristics. Calycopterin and its 4′-methyl ether are markedly toxic.

An upper limit of identification exists for the lanthanum nitrate test for acetate.
A definite blue colour is obtained in the test for concentrations of acetic acid ranging from 120 mg. to 0·2 mg. per c.c.

Apigenin does not undergo persulphate oxidation satisfactorily. But acacetin, its monomethyl ether and analogous higher members do so. By the methylation of the products (quinols) the fully methylated ethers of isoscutellarein, 8-hydroxyluteolin and 8-hydroxytricetin could be readily obtained. Demethylation of the quinols or their methyl ethers with aluminium chloride is not successful. Boiling with hydriodic acid produces isomeric change yielding conveniently scutellarein and the higher members. 6-Hydroxy-tricetin and its derivatives are newly described.
