Jacobi’s Lectures on Dynamics

The present supplement to C.G.J. Jacobi's collected works contains the second revised edition of the "Lectures on Dynamics" edited by A. Clebsch in 1866 without the five treatises from Jacobi's literary estate added to them at that time.
According to the plans drawn up for the publication of Jacobi's collected works the latter along with the major treatise "Nova methodus aequtionen differentiales partiellen primi ordinus inter numerum variabilium quemcunque propositas integrandi" , (New meth- ods for the integration of first order partial differential equations of any number of variables), also edited by Clebsch, and a few other shorter works will form the contents of the fifth volume. As has been remarked in the preface to the first edition of the "Lec- tures", they are based on the not es prepared with great care nad accu- racy by C. W. Borckhardt who attended the lectures given by Jacobi at the University of Königsberg in the winter semester of 1842-43. The changes made by Clebsch in the edition of Brochardt's text are minor. Also Mr. E. Lottner, the publisher of the new edition, has only made slight stylistic changes in certain places where the express ions were not precise or sufficiently clear, and for the rest has confined himself to cor- recting a few printing and computational errors remaining in the first edition.
