The strata around Horsham, (which is situated in the Wealden formation) are celebrated for the abundance of the exuviÆ, of large saurian animals.—Many of the bones of the Iguanadon, an enormous reptile, which was formerly an inhabitant of these districts, are now in the possession of Mr G. B. Holmes, of Horsham, by whom these particulars are obligingly communicated. The animal which more nearly approximates to it, than any other now in existence, is the Iguana Cornuta a native of the tropical parts of America, and from its resemblance to which it has received its name; but more particularly on account of the teeth of the Iguanadon, which resemble those of no other animal than the Iguana, of which one species (the Cornuta,) has, like the Iguanadon, a single horn. If we take the Iguana as our model, and attempt to reconstruct the enormous Iguanadon in just proportion, from the relics which have been frequently exhumed, we shall produce a monster 100 feet in length, which there is every reason to believe is not an exaggeration.—Besides the Iguanadon, we find the bones of the crocodile, the Plesiosaurus, the turtle, and other amphibious reptiles; with the carbonized remains of monocotyledoneous plants, arborescent ferns, and palms, &c.
