Diagrams, experimental equipment and results by James Monckman Six diagrams of experimental apparatus, cut from pages 3-10, showing equipment used by Monckman in his investigations into the specific resistance and other properties of sulphur; these are followed by three graphs titled 'Effect of change of temperature on the conductivity of sulphur', 'Boiling point under varying pressure' and 'Expansion from 120 degrees to 350 degrees' respectively. Subject: Physics Prints of these diagrams were published in volume 46 of the Proceedings of the Royal Society alongside the paper 'The specific resistance and other properties of sulphur'. 1888
