First Paragraph
The Oceans opens with a discussion of bottom topography and closes with a discussion of sediments. These chapters are not so much introduction and summary, however, as sturdy bookends to hold the Physics, Chemistry, and General Biology, of the book’s subtitle. In fact, the last chapter seems to have been an afterthought, inasmuch as it was penned into the original typed list of chapters (SIO Archives Collection 81-123, v. 1, p. 8).
