“ Franks, who, it is well known, has paid very great attention to prehistoric matters—in fact he had been attracted to Switzerland by these very discoveries. With great kindness he allowed me to accompany him to Schaffhausen, where a large portion of these relics are deposited in the Museum there, and also to the cave itself. Dr. Von Mandach, the President of the Schaffhausen Natural History Society, accompanied us. ”
