Only now, after a significant part of the gleanings has been prepared for printing, do we have the ninth and tenth volumes of the Erlangen correspondence. In order not to omit anything that we can do for the best possible production of our collection of letters, we add here the additions and corrections that result for us from the two volumes mentioned. Although it can already be seen from the time indications where the following pieces belong, we nevertheless also place the numbers above them, which possibly result from the improvements.
No. 1789a .
