Resumoof the double-bond.R. MANZONI-ANSIDEI: Raman spectrum of dimethylfurazan and of dimethyloxdiazole.G. B. BoNINo, R. MANZONI-ANSIDEI and D. DINELLI: Raman spectrum of some substituted pyrrole aldehydes.These all have an intense, diffuse line at 1,620-1,650 cm.-1 due to the strongly perturbed C=O group, and a line at 1,56o-1,570 em.-', which is probably due to a double bond. A. MANGINI : Condensation products of oximes with aromatic diazo compounds.A. ORRU: Behaviour of the electrical conductivity of hen's egg yolk at increasing and decreasing temperatures.There is no hysteresis phenomenon in the case of egg yolk.D. DINELLI: Colouring substances in the shell of cassowary eggs.M. FIORE : Presence of W ielandiella angustijolia, Nath., in Veronese Lias (Rovere di Velo).F. RODOLICO : Chemical composition of the
