On the Map of northern Greece.

1. This map has upon the whole been constructed in the same manner as that of the Peloponnese. It has been founded on mathematical calculations of the longitude and latitude, and bearings taken by the compass: the routes of ancient and modern travellers have been entered; and in this manner was obtained a more certain foundation than most of the modern maps could afford, as these must themselves be examined by the same process before they can be followed with confidence. Of the maps whose assistance was then called in, no one was more used, because none furnishes more details, and appears in general to be executed with such accuracy as the “Carte physique historique et routière de la Grèce,” published in four sheets at Paris in 1826, and prepared with great care by Lapie, the “géographe du “roi,” from materials collected by the French ambassador at the Porte, count Guilleminot, and by count Fromelin, as well as from the accounts of modern travellers, and the astronomical observations of Gauttier and Smith.

The following remarks are intended merely to state the chief authorities on which my map is grounded, and to enter into detail only in fixing the boundaries between the different tribes and states; one of the chief objects of this map being to give a clear view of the outward political condition of Greece at the beginning of the Peloponnesian war.
