Pure and Applied Chemistry

The proceedings of the Eleventh International Congress of Pure and Applied Chemistry, held in London from July 17 to 24, covered a wide variety of topics of medical interest. Joint meetings between sections primarily concerned with human beings, animals, and plants proved of special value. Sir Henry Dale's congress lecture on "The Part of Chemistry in the New Therapeutics " was published in our last issue (Aug. 2, p. 161). The report which follows excludes also discussions on bacterial chemotherapy, the principal points from which were summarized last week in a leading article (p. 179), and the reported discovery of a lactation vitamin which was the subject of an annotation (p. 181).
