It was the same author who, in a subsequent work, described and figured the fossil skeleton of a large salamander which he believed to be that of a child destroyed in the flood, and which he called “Homo diluvii testis.” In this specimen, which was discovered in the Tertiary rocks of Oeningen, and which is still preserved among the historically as well as scientifically famous fossils of the museum at Haarlem under the name _Andrias Scheuchzeri_, Scheuchzer thought that he detected, not only the skeleton of a child, but even its brain, liver, muscles, etc.! His engraving of this “Witness of the Flood,” the “sorrowful skeleton of an old sinner drowned in the Flood,” as also that of the ichthyosaur vertebrae of Altorf, were afterward printed in the famous “Copper Bible” as positive proof of the literal accuracy of the biblical record. Earlier than the publication of these figures by Baier and Scheuchzer, at the very close of the seventeenth century, a Welsh naturalist by the name of Lluyd, in a large and beautifully illustrated work, figured—perhaps for the first time—remains of ichthyosaurs, which he believed to be those of fishes. But Lluyd accounted for these and all other fossil remains by a very different theory from that of Scheuchzer and the theologians—a theory which at one time had many adherents among scholars. He believed that the spawn of fishes or the eggs of other creatures had been carried up from the seas and lands in moist vapors into the clouds, whence they had descended in rain, penetrating the earth to give origin to the fossils; in other words, he believed that all fossils grew in the earth from germs of the living animals that inhabited the land and seas. Certainly the old philosophers were hard driven to make facts agree with theories! Remains of ichthyosaurs, abundant as they were and are in many deposits in England and Germany, attracted very little attention from the naturalists of the eighteenth century after the time of Scheuchzer and Baier, and nothing more was written about them until 1814, when Sir Everard Home, an English comparative anatomist, in an extensive series of large and finely illustrated, though rather discursive, works, described and figured a number of good specimens. To the animal the remains of which he rather vaguely and imperfectly described, he gave in 1819 the name _Proteosaurus_, in the belief that it was allied to the living _Proteus_, a salamander.
