 How carefully Bopp matured this work emerges from the series of monographs printed in the "Transactions of the Berlin Academy" (1824–1831), which preceded it.They bear the general title "Vergleichende Zergliederung des Sanskrits und der mit ihm verwandten Sprachen (Comparative Analysis of Sanskrit and its related Languages)".Two other essays (on the "Numerals", 1835) followed the publication of the first part of the "Comparative Grammar".
