In the CPOSS references the first number in clarendon type is the number of the
volume ; the second number refers to the chapter; and the succeeding number refers to the
" §," section. Thus 5. 88, 24 refers to § 24, chapter 38, volume 5.
The oxides, hydrides, halides, sulphides, sulphates, carbonates, nitrates, and phosphates
are considered with the basic elements ; the other compounds are taken in connection with
the acidic element. The double or complex salts in connection with a given element include
those associated with elements previously discussed. The carbides, silicides, titanides,
phosphides, arsenides, etc., are considered in connection with carbon, silicon, titanium, etc.
The intermetallio compounds of a given element include those associated with elements
previously considered.
The use of triangular diagrams for representing the properties of three-component
systems was suggested by G. G. Stokes (JFVoc. Roy. Soc.t 49. 174, 1891). The method was
immediately taken up in many directions and it has proved of great value. With practice it
becomes as useful for representing the properties of ternary mixtures as squared paper is for
binary mixtures. The principle of triangular diagrams is based on the fact that in an equilateral
triangle the sum of the perpendicular distances of any point from the three sides is
a constant. Given any three substances A9 B, and Cf the composition of any possible
combination of these can be represented by a point in or on the triangle. The apices of the
