The theory of determinants in the historical order of development, by Sir Thomas Muir.

JACOBIANS (CAYLEY, 1847) 237 may say that When n n-ary rth-ics vanish, their Jacobian and each of its first differential-qutiients will vanish also. The connection of this with the problem of elimination can be indicated in a few words. Jacobi's determinant p being of the third degree in x,1 x2, x3, its first differential-quotients are like f1, f2, f3 linear in x12, X22, 32, X2x3, 31 X1s2; and consequently the resultant is at once obtained as a six-line determinant. CAYLEY, A. (1847, February). [On the differential equations which occur in dynamical problems. Cacnbridge and Dub. Math. Journ., ii. pp. 210-219; or Collected Math. Papers, i. pp. 276-284.] This is a short exposition of Jacobi's elaborate memoir of 1844 with considerable variation in the details. The portion (~ 1) which concerns us is of course that referring to the "fundamental lemma." This is established in its third form, the proof, like that originally given by Jacobi, being dependent on the theorem DR _ x7, Dx1, but differing in appearance, mainly because of the use of differentials. BERTRAND, J. (1851, February). [Memoire sur le determinant d'un systeme de fonctions. Journ. (de Liouville) de Math., xvi. pp. 212-227; abstract in Comptes Rendus.... Acad. des Sci. (Paris), xxxii. pp. 134-135.] Recalling how Jacobi had insisted on the marked analogy between a functional-determinant and a differential-coefficient, Bertrand at once intimates the adoption of a new definition of the former, which in his opinion makes the analogy still more striking, and from which the properties of the determinant are deducible like mere corollaries. Save that A and 8 are used where Bertrand without distinction uses d, the following is the definition:-If f, f2,..., f be
