referred them to the tertiary because they were covered by the eocene 

 fossiliferous sands ; but the bones were found on the shore of the 

 Washita River, where the debris of the tertiary has enveloped them, 

 and led to the mistake. I traversed the section of Alabama where 

 the Zeuglodon occurs, and collected the organic remains of the lime- 

 stone which contains the bones, and therefore I can say without hesi- 

 tation or doubt, that the gigantic animal is restricted to this limestone, 

 the vertebrae of the different specimens lying in a relative position to 

 each other that could only occur where an animal has remained undis- 

 turbed upon the spot where it died. T. A. Conrad. 



11. Professor Jolinsuri's Analyses of Anthracite and Iron Ore. — In 

 the Journal of the Franklin Institute, November, 1S39, is a valuable 

 paper by Prof. Walter R. Johnson, Prof. Chem. and Nat. Phil. Med. 

 Dept. Penn. Coll., entitled — Analysis of some of the Anthracites 

 and Iron Ores found on the head waters of Beaver Creel:, in the 

 Counties of Luzerne, Northampton and Schuylkill, Pa. The paper 

 contains an account of the geological arrangement of the coal fields^ 

 lying near the head waters of the Beaver Creek, which were explored 

 by Prof. J. in the summer of 1838, and from which the specimens 

 analyzed were obtained. From the cutting made for the railroad 

 leading to the mines of the Beaver Meadow Coal Company, it is evi- 

 dent that there is more than one flexure in the Beaver Meadow Coal 

 Trough. " In this cutting there is displayed a nearly vertical bed of 

 coal, more than 30 feet in thickness ; having, however, a real posi- 

 tion or dip of S. 10° E. 85°, and consequently a course or strike N. 

 80° E." To the geological account succeed the descriptions and 

 analyses of various specimens of anthracite. 



No. 1. Sp. grav. 1.613. Water, 3.43; gaseous matter volatile at 

 bright red heat, 4.08; carbon not volatile by simple heat, 87.48; 

 earthy matter, 5.01=100. 



No. 2. Sp. grav. 1.594. Water, 3.26; other matter volatile at red 

 heat, 1,05; carbon, 91.69; earthy matter, 4. = 100. Analysis of the 

 ashes of No. 1 and 2, gave, on an average, silica, 52.375 ; alumina, 

 36.745; peroxide of iron, 8.125; lime, 1.550; magnesia, 1.275. 



No. 3. Sp. grav. 1.630. Volatile matter, 9.6; carbon not volatiliza- 

 ble by simple heat, 85.337; earthy matter, 5.063=100. The com- 

 bustible gas given out in the distillation of this coal is of considera- 

 ble amount, and indicates it as a fuel well adapted for use under steam 

 boilers. 



No. 4. Sp. grav. 1.560. Water and combustible gases, 6.89; car- 

 bon not volatile by simple heat, 91.64 ; earthy residuum, 1.47=100.
