have determined the quantities of radon and of radium actually present in the water obtained from three representative radiumwater generators which were operated as directed by the manufacturers. They conclude that steady drinkers of such water are not in danger of radium poisoning.
"The alleged therapeutic value of slightly radio-active waters probably rests more on the larger daily doses of water dcunk than on 'the radon contained therein.

Glucosone.-This organic compound is a derivative of glucose and contains both an aldehyde group and a ketone group. KENDAL CARTWRIGHT DIXON AND KENNETH HARRISON (Biochem. Jour., 1932, XXVI, 1954-1958) have devised a new method for its preparation by the oxidation of fructose in aqueous solution by means of selenious acid at the temperature of boiling water. Their researches have failed to reveal any evidence of the formation of glucosone in the animal body as a product of metabolism. J. S. H.
