Excerpt from A Journey Through Persia, Armenia, and Asia Minor, to Constantinople, in the Years 1808 and 1809: In Which Is Included, Some Account of the Proceedings of His Majesty's Mission, Under Sir Harford Jones, Bart, K. C., To the Court of the King of Persia. "Amasia, is the result of my own observation, corrected by the same masterly hand. It terminates at Amasia, because my journey from that place to Constantinople was performed as much by night as it was by day, and prosecuted with too great speed to permit me to observe with accuracy. Besides which, in Turkey, where the people are much more jealous and watchful of travellers than in Persia, I found that I could not make my remarks so much at my casc as I wished, although assisted by the of a Persian dress. The courses and distances, noted in the journal, are only to be regarded as a kind of dead reckoning, subject to correction by the application of latitudes in certain places, and of approximated positions in others."
