The climate of Greenland nmst have greatlychanged since such vegetation fiourished there. In the neiglibtuhood of G^ningen, near Coustance, inGermany, are miocene beds of marls, limestone, andlignite or im[)erfect coal. The Rhino flows throughthera, exposing beds on both sides in clilfs from sevenhundred to nine hundred feet in heiulit. In these beds Fig. ( ClCiiin^iiiHia. have been found leaves of the poi)lir, willow, mapb-, nn-den. and olm. The buckthorn has also been found, and 224 LKCTURES ON GEOLOCJf. wluit is supposed to be a speci(?s of wheat. In tl)e sarnobeds liave been foiuid insects, shells, fislies, turtles, tor-toises^birds, and an animal rescniblinj^ the conuuon fox,Galecynus (Emngensis (weasel-dog of G^ningen), Fig gives it an intermediate position between thenule-cat and dog. Amber has been found in the beds at Marthas Vine-yard and at Brandon ; but the greatest amount has beenobtain(;d on tie shores of the Baltic, washed out of thelignite ]>eds Iiy the waves. Species of pines existpd,from which gum, or resin, flowed ; and, becoming fossil-ized, amber Avas the result. In flowing down the tree,insects, spiders, small crustaceans, and leaves werecover(jd; and thus we find them pieserved in the trans-jjarent ami)er.
