[85] “Recherches sur les causes des principaux faits physiques,” par J. B. Lamarck. Paris. Seconde année de la République. In the preface, Lamarck says that the work was written in 1776, and presented to the Academy in 1780; but it was not published before 1794, and, at that time, it presumably expressed Lamarck’s mature views. It would be interesting to know what brought about the change of opinion manifested in the “Recherches sur l’organisation des corps vivants,” published only seven years later.
