This etching gives diagrams of "The Eclipse of the Sun as it will appear at London on July 14 1748" and of the motion of the Earth around the Sun. In the background is a view over the city of London, with St Paul's Cathedral prominent to the left. In the foreground is what appears to be a water reservoir, so it is possible that this was close Sadler's Wells and, as a pencil annotation suggests, within Islington. There is a group of a dog and two male figures, one of whom is observing the eclipse with a hand-held telescope, at the bottom right. The image was originally published in the Universal Magazine in 1748 at the time of an eclipse that was partial in London and total only north of the Firth of Forth.
