This is a hand-colored lithograph titled "The Mineralogist," published in January 1830. It depicts a man, presumably a mineralogist, seated on a rocky outcrop in a rugged landscape. The man is dressed in somewhat eccentric clothing. He wears a tall, elaborate hat adorned with flowers and what appear to be mineral specimens. His coat is a vibrant green with a contrasting yellow collar and cuffs. He has on brown breeches and high, patterned boots. A colorful bag hangs from his shoulder, and he's equipped with tools of his trade: a hammer, a chisel, and a small bag for collecting specimens. He is intently examining a mineral specimen with a magnifying glass, while sketching it on a piece of paper with a pencil. The rocky outcrop he sits on is covered in small plants and mineral formations. The background shows a mountainous landscape with a body of water in the distance. The overall style is somewhat caricatured, with exaggerated features and vibrant colors. The image is signed by C. Spratt and G.E. Madeley.
