The English general Elliott commanded the post of Gibraltar, against which the combined forces of France and Spain made a vigorous but fruitless attack in the year 1781. This attack furnished the subjects for two celebrated pictures alluded to in the eighth book: _The burning of the Floating Batteries_ painted by Copley; and _The Sortie_, painted by Trumbull.

The instrument known by the name of Hartley's Quadrant, now universally in use and generally attributed to Dr. Hartley, was invented by Thomas Godfrey of Philadelphia. See Jefferson's Notes on Virginia; likewise Miller's Retrospect of the Eighteenth Century, in which the original documents relative to Godfrey's invention are fully detailed.
