, which resembled our alligators. It was thirty-five feet
in length. Then there was the Hylaeosaurus, a monster twenty-five
feet in length, with a cuirass of bony plates."

"But none of these correspond with More's description of the monster
that fought with the galley."

"No," said the doctor, "I am coming to that now. That monster could
have been no other than the Plesiosaurus, one of the most wonderful
animals that has ever existed. Imagine a thing with the head of a
lizard, the teeth of a crocodile, the neck of a swan, the trunk and
tail of a quadruped, and the fins of a whale. Imagine a whale with its
head and neck consisting of a serpent, with the strength of the former
and the malignant fury of the latter, and then you will have the
plesiosaurus. It was an aquatic animal, yet it had to remain near or
on the surface of the water, while its long, serpent-like neck enabled
it to reach its prey above or below with swift, far-reaching darts.
Yet it had no armor, and could not have been at all a match for the
ichthyosaurus. More's account shows, however, that it was a fearful
enemy for man to encounter."

"He seems to have been less formidable than that beast which they
encountered in the swamp. Have you any idea what that was?"

"I think it can have been no other than the Iguanodon," said the
doctor. "The remains of this animal show that it must have been the
most gigantic of all primeval saurians. Judging from existing remains
its length was not less than sixty feet, and larger ones may have
existed. It stood high on its legs; the hind ones were larger than the
fore. The feet were massive and armed with tremendous claws. It lived
on the land and fed on herbage. It had a horny, spiky ridge all along
its back. Its tail was nearly as long as its body. Its head was short,
its jaws enormous, furnished with teeth of a very elaborate structure,
and on its muzzle it carried a curved horn. Such a beast as this might
well have caused all that destruction of life on the part of his
desperate assailants of which More speaks.

"Then there was another animal," continued the doctor, who was
evidently discoursing upon a favorite topic. "It was the one that came
suddenly upon More while he was resting with Almah after his flight
with the run-away bird. That I take to be the Megalosaurus. This
animal was a monster of tremendous size and strength. Cuvier thought
that it might have been seventy feet in length. It was carnivorous,
