Archives des sciences physiques et naturelles
A French-language scientific journal issued in 1919 by the Société de Physique et d'Histoire Naturelle in Geneva for researchers in physics and natural history. Plates mix line diagrams of circular microscope fields scattered with diatom and desmid forms, outline sequences of dividing algal cells with numbered captions, and a halftone rubbing of a Chinese stone star chart — usable as pattern fields, cell silhouettes, and inscribed-stone texture.
