[303] In this connection reference should be made more especially to the paper by Roberts-Austen and Stansfield, "Sur la constitution des alliages métalliques," in the _Rapports du congrès international de physique_, 1900, I. 363; J. A. Mathews, _Journ. of the Franklin Inst._, 1902; Gautier, _Compt. rend._, 1896, 123. 109; Roberts-Austen, "Reports of the Alloys Research Committee," in _Journ. Inst. Mechan. Engineers_, from 1891 to 1904; and the papers by Heycock and Neville, published in the _Journ. Chem. Soc._, and the _Trans. Roy. Soc._ since 1897; also Neville, _Reports of the British Association_, 1900, p. 131. Reference must also be made to the important metallographic investigations by Tammann and his pupils, and of Kurnakoff (_Zeitschr. anorgan. Chem._, vol. 40 and onwards), and also to those of Shepherd, _Journ. Physical Chem._, 8. A bibliography of the alloys is given in _Zeitschr. anorgan. Chem._, 1903, 35. 249.

[310] The melting point of pure iron is given by Carpenter and Keeling (_Journ. Iron and Steel Inst._, 1904, 65. 224) as 1505°. [311] _Zeitschr. für Elektrochem._, 1904, 10. 491.
