340 FOSSIL REPTILES. 



first is yet, in part, concealed under the cranium. The second 

 is very entire, and exactly of the same form as in our living 

 aquatic salamanders. Thus, there can be no doubt but that the 

 pretended anthropolite of CEningen was an aquatic salamander, 

 of a size gigantic in its genus. 



We shall conclude this account by saying a few words re- 

 specting those celebrated quarries where the above described 

 fossil was found^ and an immense number of others of various 

 kinds. 



The Rhine, after having formed the lake of Constance, and 

 narrowing near the town of the same name, widens again 

 to form the lake called Zellersee, and does not resume the 

 ordinary width of its bed until it approaches the little town of 

 Stein. 



On the right bank, a little above Stein, is the village of 

 CEningen, formerly belonging to the Bishop of Constance, and 

 at present, like the rest of the bishopric, to the Grand Duke 

 of Baden. 



The quarry, which abounds in impressions of fish, &c., is 

 three-quarters of a league from this, on the southern declivity 

 of a mountain termed Schiener-berg, and at least five hundred 

 feet above the level of the lake. A small stream runs along its 

 eastern side. The elevated part of the mountain is of a soft 

 micaceous sandstone, and rolled blocks of red and green granite 

 are found in the fields. 



The quarry is extended over about two hundred and seventy 

 feet in length, and is about thirty deep, but its bottom is often 

 full of water. Beneath the vegetable soil is found, at first, a 

 friable bluish marl, two feet in thickness, which is employed 

 in making tiles and bricks, for want of better clay. Under 

 this marl are many feet of a primitive schistus, yellowish 

 grey, soft, with very thin laminae, and filled with vegetable 

 impressions. Then comes a second bluish marl, like Uie first, 

 about half a foot in thickness, and without organized bodies. 

 All the succeeding strata are calcareous, and when they are
