Le cercle d'Abbeville: Paléontologie et préhistoire dans la France romantique. Edition établie par Marie-Françoise Aufrère.

In May 1940 the Boucher de Perthes Museum in Abbeville was destroyed by bombing. However, in the years before the war Leon Aufrère made copies of archives and correspondence, which became the source material for this book on the circle of scientific amateurs associated with Boucher de Perthes. The book was published posthumously by Aufrère's daughter.
