Vernunftlehre

This was a famous book 200 years ago because the great Immanuel Kant had used *only* this book to teach his course on Logic in the University of Konigsberg before he became famous himself. Why Meier's book? Because Meier was a disciple of Leibniz, the greatest logician in German history to that point, and Meier made Leibniz' logic easier and more accessible to University students. I look forward to the time when OpenLibrary can obtain a copy of this famous set.
