Zero of Animal Life probably about 300 fathoms.

The corals do not look much worn, but still appear to have been dead. There are some delicate shells of molluscs from depths beyond 500 fathoms, where they were certainly living.

...It is a very remarkable fact that the species of shell-fish common to Greenland and Finmark are not all inhabitants of deep or moderately deep water .... That these littoral mollusks indicate by their presence on both sides of the Atlantic, some ancient continuity or contiguity of coast-line is what I firmly believe.

Palaeontological research exhibits, beyond question, the phenomenon of provinces in time, as well as provinces in space. Moreover, all our knowledge of organic remains teaches us, that species have a definite existence, and a centralization in geological time as well as in geographical space, and that no species is repeated in time.

As to giving credit to whom credit is due, rest assured the best way to do good to one's-self is to do justice to others. There is plenty for everybody in science, and more than can be consumed in our time. One may get a fair name by suppressing references, but the Jewish maxim is true, 'He who seeks a name loses fame.'

The naturalists of our own time hold equal faith in the wonders of the sea, but seek therein rather for the links of nature's chain than for apparent exceptions.
