In the primary division of the animal kingdom, we find the type in the radiata, not one of which lives out of water. In the vertebrata, it is in the fishes. In both of these, feet are totally wanting. Descending to the class mammalia, we have this type in the cetacea, which present a comparatively slight development of limbs.
While I was observing this phenomenal creature, two jets of steam and water sprang from its blowholes and rose to an altitude of forty meters, which settled for me its mode of breathing. From this I finally concluded that it belonged to the branch Vertebrata, class Mammalia, subclass Monodelphia, group Pisciforma, order Cetacea, family . . . but here I couldn't make up my mind.
The teeth are much more numerous, although the molars exhibit the zeuglodont double fang; the nasal bones are very short, and the upper surface of the rostrum presents the groove, filled up during life by the prolongation of the ethmoidal cartilage, which is so characteristic of the majority of the Cetacea.
Yet no single transitional form has yet been met with in spite of the multitudinous individuals preserved. Again, with their modern representatives the Cetacea, one or two aberrant forms alone have been found, but no series of transitional ones indicating minutely the line of descent.
Now then, this hole didn't make itself, and since it hadn't resulted from underwater rocks or underwater machines, it must have been caused by the perforating tool of some animal. Now, for all the reasons put forward to this point, I believed that this animal was a member of the branch Vertebrata, class Mammalia, group Pisciforma, and finally, order Cetacea.
The same moral is inculcated by the study of every other order of Tertiary monodelphous Mammalia. Each of these orders is represented in the Miocene epoch: the Eocene formation, as I have already said, contains Cheiroptera, Insectivora, Rodentia, Ungulata, Carnivora, and Cetacea.
This method of whaling being quite new to our whalemen, it was necessary, at great cost, to hire American officers and harpooners to instruct them in the ways of dealing with these highly active and dangerous cetacea.
This powerful creature is heard a long way off when he throws to a great height columns of air and vapour, which look like whirlwinds of smoke. These different mammals were disporting themselves in troops in the quiet waters; and I could see that this basin of the Antarctic Pole serves as a place of refuge to the cetacea too closely tracked by the hunters.
VIII. CETACEA. Whales are so frequently seen that they have been captured within sight of Colombo, and more than once their carcases, after having been flinched by the whalers, have floated on shore near the lighthouse, tainting the atmosphere within the fort by their rapid decomposition.
Even the comparatively scanty Eocene fauna yields examples of the orders Cheiroptera, Insectivora, Rodentia, and Perissodactyla; of Artiodactyla under both the Ruminant and the Porcine modifications; of Carnivora, Cetacea, and Marsupialia.
