They were clumsy brutes, and though their limbs were evidently built with reference to powerful movements, perhaps climbing, or at least rising on their hind quarters, the act of climbing with them cannot have had anything of the nimbleness or activity generally associated with it. On the contrary, they probably were barely able to support their huge bodies on their hind limbs, which are exceedingly massive, and on the stiff, heavy tail, while they dragged down with their front limbs the branches of the trees, and fed upon them at leisure. The Zoölogical Museum at Cambridge is indebted to the generosity of Mr. Joshua Bates for a very fine set of casts taken from the Megatherium in the British Museum. They are now mounted, and may be seen in one of the exhibition-rooms of the building. Large Reptiles, but very unlike those of the Cretaceous and Jurassic epochs, belonging chiefly to the types of Turtles, Crocodiles, Pythons, and Salamanders, existed during the Tertiary epochs. The wood-cut below represents a gigantic Salamander of the Tertiary deposits. It is a curious fact, illustrative of the ignorance of all anatomical science in those days, that, when the remains of this reptile (Audrias, as it is now called) were first discovered toward the close of the seventeenth century, they were described by old Professor Scheuchzer as the bones of an infant destroyed by the Deluge, and were actually preserved, not for their scientific value, but as precious relics of the Flood, and described in a separate pamphlet, entitled, "Homo Diluvii Testis." Among the Tertiary Reptiles the Turtles seem to have been a very prominent type, by their size as well as by their extensive distribution. Their remains have been found both in the far West and in the East. The fossil Turtles of Nebraska are well known to American naturalists; but the Oriental one exceeds them in size, and is, indeed, the most gigantic representative of the order known thus far. A man could stand under the arch of the shield of the old Himalayan Turtle preserved in the British Museum. [Illustration] [Illustration]
