Summary:

Discusses GCW’s Notes on the presence of animal life at vast depths [1860]. Asks for information on the decay of exuviae of organisms at bottom of sea. Has GCW reason to believe extensive areas of sea-bottom are bare? Is he sure rounded pebbles were not dropped by icebergs? Curious that water at such depths retains oxygen.
