Post Lot Text
Corrected page proofs of the offprint issue of an article published in the Revue encyclopédique c. 1830. Ampère made numerous autograph corrections to every page, which were adopted in the original edition, and one substantial addition of five lines of verse to the thirteenth stanza of his mnemonic poem, which remained excluded from the published version. A copy of the final offprint is included with the lot. After 1827 Ampère's scientific activity declined and he turned exclusively to philosophy and his system of classification of the sciences, which ultimately resulted in his Essai sur la philosophie des sciences (1834). The present Notice represents an early stage of this classification and includes a Latin mnemonic poem as an aid to the author's students at the Collège de France.
