'Mount Vesuvius, as represented at the Surrey Zoological Gardens', London, 1837. A recontstruction of an eruption of the volcano Vesuvius, showing lava, flames and smoke pouring from the crater. A note below the title explains that the image can be held up to the light to enhance the effect: This print is first seen by day, & upon holding it before the light it exhibits the eruption, conveying the idea, the wonderful works of nature.
