• DUBLIN Royal Dublin Society, December 17, 1935. H. H. DIXON: Sap movement in the bast. M. J. GORMAN and THOMAS TUBPIN: An ineffective strain of nodule organism on red clover. This strain was isolated locally and is one of those which produces numerous small nodules distributed over the finer roots. In culture the ineffective strain did not grow in the sugar broths used. An effective strain studied concurrently grew well on the sugar media and produced, as is usual, a slight amount of acid. Other differences between the strains were noted. D. A. WEBB: The nitro-chromic reaction and its application to the estimation of small quantities of alcohol. By a modification of Agulhon's reagent (potassium dichromate in nitric acid) the strength of alcoholic solutions of the order of 100 mgm. per litre can be estimated to within two per cent, and more approximate estimations made down to 2.5 mgm. per litre. The method may be applied to blood serum, urine, milk, coloured fluids and expired air.
