‎First edition of a main paper dealing with n-dimensional geometry.""""Of the papers devoted to n-fold integrals Jacobi's 1834 paper """"De binis quibuslibit...."""" is of crucial importence in this connection (the theory of algebraic forms of variables). Here, besides the problem of computing multiple integrals, an importent problem of the theory of algebraic forms is solved."""" (Andrei Nik. Kolmogorov).‎
