The Lord Jesus Christ was "the Seed," the One who loved us and gave Himself for us: the One whom "God so loved the world" as to give, "that whosoever believes in Him should not perish, but have everlasting life;" the One who "once suffered for sins, the just for the unjust, that He might bring us to God."

We have been learning something of how dreadful the bites of serpents are, how full of deadly poison: and we have been reading how, by listening to the old serpent, the poison of sin—having our own will, and thinking hard thoughts of God—came into the hearts of God's creatures, bringing sorrow, and shame, and death with it. How beautiful that the righteous One in whom was no sin, and who come to take away our sins, should tell us that "As Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up." The serpent of brass was not kept in Moses's tent; it was lifted high, for all to see it. God, who knew His people's sin, and had sent those fiery serpents to bite them, had Himself told Moses to make that serpent of brass, and those who were bitten had only to look at it and live. If they looked at their own hurt, or at each other, or at Moses—all was of no avail; but "it came to pass that if a serpent had bitten any man, when he beheld the serpent of brass, he lived."

God—who knew that every one of us born into this world is born away from Him, and with the dreadful poison of sin, like the serpent's bite, in us—gave His only begotten Son to be lifted up, that "whosoever believeth in Him should not perish, but have everlasting life." And He tells us to look at Him and live, just as the poor sinful people, dying of the serpent's bite, looked at the serpent of brass, and their deadly wound was healed. God has told us to look straight to His Son, dying for sin, dying in our stead; but it is not our looking that saves us, it is the blessed Saviour whose name is called Jesus, "for He shall save His people from their sins."

I must not forget to tell you that many of the extinct animals whose skeletons are to be seen in museums belonged to the class of Reptiles.

We read that "God created great whales"—or sea monsters—and remains have been found of enormous lizard-like creatures. One has been called the Fish-lizard; it seems to have had a crocodile's head, with a body like that of a small whale.

Another had a long swan-like neck, the body and tail of a quadruped, and paddles like a turtle.

Another, called the Winged-lizard, had bat-like wings and dreadful jaws armed with numerous teeth. All these "Saurians" are believed to have frequented the sea or rivers; but another called the Great-lizard, was a land-animal, as was the Forest-lizard, and a monster kind of Toad with very curiously formed teeth. But no description will give you an idea of the size of these creatures, though I may tell you that a party of gentlemen dined inside the body of one great extinct lizard at the Crystal Palace, where models, not very accurately made, of the most remarkable ancient animals are to be seen. I think my first thought when I see the actual remains of these old-world monsters, with their terrible jaws, is that of thankfulness that they have passed away from sea and land. But we know that God who created them "saw that it was good," and in the Book of Job we may read His description of mighty and terrible creatures which show forth His power.

We were speaking of a monster toad whose fossil remains have been found; and I must tell you that before we had done with the "Creeping Things," I was asked a difficult question. "To what class do the frogs and toads and newts belong? Are they Vertebrate animals? Do they belong to the land or the water?"

I said they certainly do belong to the great Backboned family, and are placed in a class by themselves, as they are neither Mammalia, Birds, Fishes, nor Reptiles, properly speaking, and are called Amphibia, because they live, as it were, a double life.
