This plan is meant to convey a "perfect idea" of the original arrangement of Stonehenge as it once was, rather than in a familiar state of ruin. The horizontal stones are not represented, but Silliman asks the reader to supply them with their imagination. More information can be found on page 91.

This plate is from A Journal of Travels in England, Holland and Scotland, and of Two Passages Over the Atlantic, in the Years 1805 and 1806, Vol. 2., published in 1812. This travel log of Benjamin Silliman (1779-1864) details his research In England, Holland, and Scotland. Silliman founded the American Journal of Science and discovered a way to distill petroleum. Written in first-person, this book gives an insight into Silliman's personal feelings and observations about his experiences in several cities and towns across England, Holland, and Scotland, as well as his journey back to the United States. It notably contains several fold-out diagrams of Stonehenge.
