NOTICE EXPLANATORY OF A CHART
OF
THE SOUTH SIDE OF THE GULF OF PE-CHE-LEE, YELLOW SEA.
[Sidenote: First meridian used in constructing the chart.]
In constructing this chart, I have assumed the longitude of the fort at the mouth of the Pei-ho to be 117º 49' east of Greenwich, or 11' west of the place where the squadron lay at anchor. From this the difference of longitude was measured by two chronometers. The latitudes were ascertained by frequent observations of the stars, as well as of the sun.
