Atti della Accademia di scienze, lettere e arti di Palermo.
Proceedings of the Accademia di scienze, lettere e arti di Palermo for 1845, issued by the academy itself in Palermo for Sicilian scholars and exchanging learned societies. The plates hold numbered microscope studies of small spiral, coiled and spined shells and seed-like bodies, drawn in soft pencil-toned lithography on cream paper, useful as isolated round motifs, spiky silhouettes and spiral diagrams.
