Paper, 'The specific resistance of sulphur and other properties' by James Monckman Monckman writes: 'It is well known that sulphur in a solid state insulates electricity of very high potential, and conducts heat badly; also that it undergoes a curious series of changes when heated—melting at about 120° C., becoming thicker at 200° to 250°, more liquid at 250° to 300°, and boiling under atmospheric pressure at 440°.' Annotations in pencil and ink. Includes eight pages of diagrams of experimental apparatus and results. Subject: Physics Received 10 November 1888 / 16 November 1888. Read 6 December 1888.
