Notes difficulty of setting an east-west boundary to coral islands.

Summary

"I could think of nothing for days after your lesson on coral reefs, but of the top of submerged continents. It is all true, but do not flatter youself that you will be believed, till you are growing bald, like me, with hard work & vexation at the incredulity in the world."
