This paper will consist of seven sections :— I. On Deformations, Mixed Integrals, Characteristics, and Correlations. II. On Synthemes. III . On Terordinals. IV. On Characteristics of Terordinals. V. On Transformation to Riccatian Forms. VI. On a Particular Terordinal. VII. Conclusion. 1. On -Deformations, Mixed Integrals, Characteristics, and Correlations. 2. Meaning by/ , F,
, respectively, the four expressions and denoting by acute accents differential coefficients taken with respect to the independent variable x, suppose that then I call either of the functions / and F a deformation of the other, and O — c a mixed integral of the system / and F. 3. The presence of Y is essential to 0, and that of y to $; but in particular cases y may be absent from <£, and Y from
