Paper, 'On certain ternary alloys. Part IV: On a method of graphical representation (suggested by Sir G G [George Gabriel] Stokes) of the way in which certain fused mixtures of three metals divide them selves into two different ternary Alloys; with further experiments suggested thereby' by C R [Charles Romley] Alder Wright, C Thompson and J T Leon The authors write: 'A method of graphically representing the results of the experiments described in the previous portions of these researches has been kindly suggested to one of us by Sir G G Stokes, founded on a principle which he regards as self-evident.' Annotations in pencil and ink. Includes five pages of diagrams of experimental observations. Subject: Metallurgy / Chemistry Received 29 January 1891. Read 12 February 1891.
