XIX.] CLIFFS OF CHALK IN NORMANDY. Fig. 350. ,355 Side view of the Tete d'Homme. 'White chalk -with flints. from 50 to 80 feet high.: several of their summits terminate in pinnacles; and one of them, in particular, is so completely detached as to present a perpendicular face 50 feet high toward the sloping down. On these cliffs several ledges are seen, which mark so many levels at which the wraves of the sea may be supposed to have encroached for a long period. At a still greater height, immediately above the top of this range, are three much smaller cliffs, each about 4 feet high, with as many intervening terraces, which are continued so as to sweep in a semicircular form round an adjoining coomb, like those in Sicily before described (p. 76). If we then descend the river from Yatteville to a place called Senne- ville, we meet with a singular needle about 50 feet high, perfectly iso- lated on the escarpment of chalk on the right bank of the Seine (see fig. 351). Another conspicuous range of inland cliffs is situated about 12 Fisr. 351
