title: [Haller and Buffon: apropos of "Réflexions"].
abstract: This paper aims to throw light on the controversial issue of A. von Haller's alleged "conversion" from epigenesis to preformation. This "conversion" is usually linked to the reaction of the Swiss scholar to the publication of Buffon's theory of generation (1749). A close study of the texts published by the author of the Physiology on this occasion reveals that, far from having adopted the theory of preformation, he continued to defend epigenesis in a moderate form, a view which was not so different from that held at the same time by Buffon's associate, J. T. Needham.
