Diagrams, experimental equipment and results by [Arnulph] Mallock One page of diagrams of equipment used in Mallock's investigations into the determination of the viscosity of water, labelled figures 1-2, showing two coaxial cylinders mounted on a vertical axis and suspended by a long fine wire respectively and the equipment used to get the absolute value of the torsion-scale. This is followed by one page of graphs, labelled diagrams 1-2, showing the results of Mallock's experiments. Subject: Physics Prints of these diagrams were published in volume 45 of the Proceedings of the Royal Society alongside the paper 'Determination of the viscosity of water'. 1888
