Scull revised and extended his 1759 map, that was also dedicated to the Penn brothers, but which was published in London in 1770, and appeared subsequently in several editions through the decade including this one by Sayer & Bennett from 1770. Much of the geographical information is the same, but interestingly the earlier map is both larger and evinces greater aesthetic satisfaction. It was the first map of Pennsylvania since Thomas Holme's 1687 map of the then much smaller settlement, and represents a vast amount of on-site surveying. Dedicated to the Penn brothers, Scull's map is among the largest and finest maps produced in America in the 18th century. It was an extraordinary achievement. The map depicts Philadelphia, Bucks, Northampton, Berks, Chester, Lancaster, Cumberland, and York Counties."
