This is a hand-colored lithograph depicting a geological formation. The illustration shows a cross-section of sandstone with reddish-pink veins running through it, labeled as 'Trap Veins in Sandstone'. The sandstone itself is depicted as horizontal layers of a light yellow-tan color. The 'trap veins' appear as irregular, branching lines of reddish-pink that cut through the sandstone layers. Below the sandstone layer is a darker, bluish-gray layer, possibly representing a different geological stratum or the underlying bedrock. The image is labeled at the bottom with the text 'TRAP VEINS in SANDSTONE. Scotland, 14'. The illustration has a slightly aged appearance, with some discoloration and wear around the edges. The image is divided into sections by vertical lines, possibly indicating different areas or samples.
