Neptunian

Though the account is very interesting, I do not perceive its exact bearing on the Neptunian and Plutonian hypotheses.

In six Neptunian months a forest of graceful larches would spring up to a height of seventy or eighty feet.

But to admit the "Plutonic" origin of such widespread formations was practically to abandon the Neptunian hypothesis.

An instance of this tendency, drawn from physical science, is supplied in the Neptunian geology of Werter.

The Neptunian leader began to gesture again, and conveyed to Burl that they wanted to attack as soon as possible.
