In fact, four miles to windward a certain bubbling indicated that a huge marine mammifer was moving in the midst of the red waters. Whalers could not be mistaken in it. But the distance was still too considerable to make it possible to recognize the species to which this mammifer belonged. These species, in fact, are quite distinct.
If one species only of the whole animal kingdom died out in forty years, no more than one mammifer might disappear in forty thousand years, in a region of the dimensions of Europe.
"Perhaps there are some unhappy shipwrecked ones on that raft," said Mrs. Weldon. "We shall find out," replied Captain Hull. "But that wreck is not a raft. It is a hull thrown over on the side." "Ah! is it not more likely to be some marine animal some mammifer of great size?" observed Cousin Benedict. "I do not think so," replied the novice. "Then what is your idea, Dick?" asked Mrs. Weldon.
The germ of a higher animal a mammifer, for instance is the representative of a lower animal full-grown, like the volvox globator; the latter remaining in this initial stage, as an animalcule, through its whole existence; while the former is developed out of it, by successive stages, into a quadruped, or even into a man.
At Punta Alta in B. Blanca, I remarked how marvellous it was, that the Toxodon, a mammifer so unlike to all known genera, should have co-existed with twenty- three still living marine animals; and now we find that the Macrauchenia, a quadruped only a little less anomalous than the Toxodon, also co-existed with eight other still existing Mollusca: it should, moreover, be borne in mind, that a tooth of a pachydermatous animal was found with the other remains at Punta Alta, which Professor Owen thinks almost certainly belonged to the Macrauchenia.
The frog, for some time after its birth, is a fish with external gills and other organs, fitting it for an aquatic life, all of which are changed as it advances to maturity, and becomes a land animal. The mammifer only passes through still more stages, according to its higher place in the scale. Nor is man himself exempt from this law. His first form is that which is permanent in the animalcule.

These facts clearly shew how all the various organic forms of our world are bound up in one how a fundamental unity pervades and embraces them all, collecting them, from the humblest lichen up to the highest mammifer, in one system, the whole creation of which must have depended upon one law or decree of the Almighty, though it did not all come forth at one time.

It is generally admitted to be vapor, which, condensing suddenly by contact with the cold air, falls again as rain. However, the presence of this mammifer preoccupied the colonists. It irritated Pencroft especially, as he could think of nothing else while at work. He ended by longing for it, like a child for a thing which it has been denied.
