Pinnock's Guide to Knowledge
It's still the second ugliest map on the site - engraved on wood, incising the places/names so that they appear in white against a generally printed black background.
Displayed scale of 7 miles = 25mm, or 7.1 miles/inch; actual scale = 7.7 miles/inch, or 1:490,000.
The Guide was first published in 1833, and for this second issue they have engraved the sea and added a more complex border. We have also lost the Guide to Knowledge title, plate number and price. It will be back again in 1847, but looking very different.
