Fossil reptiles have been found in this formation inNorth Carolina, Prince Edwards Island, and Phoenixviile,Penn. In the Bunter Scmdstein, or colored sandstone ofGermany, and in Lancashire and Cheshire in England,many footprints of an enormous, frog-like re[)tilc ha\elieen found, called originally cheiroiheriuiii, or hand-beast: for the impression made by the foot of the animalresembled that of a rude, human hand. One slab con-taining them (Fig. 20), from the new red sandstone at Fig. ClicirothciiuDl Uurthi. Jena in Germany, is now in the Ward .Museum, Roches. ler, Tlie tracks of the -Iiind-fect are about eight inches louLT and five wide; and the fore-feet, Umit . . • I inches long and three wide. Ri-iiiains of this aimii d have since been discovered; and it is now known as IGG LECTURES ON GEOLOGY.
