Note 71 — CHAP. VIII.
Reading edition
The only authentic survey of the eastern coast of Japan with which I am acquainted, is that published by Jansen in his Atlas, and compiled with great accuracy from the charts and journals of the Castricom and Breskes. I have therefore adopted, wherever the identity of the situations could be nearly ascertained, the names given in that map to the corresponding points and head lands seen by us along the coast.
Jansen places the northern extremity of Japan in latitude 40° 15ʹ The point seen by us was in latitude 40° 27ʹ.
