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 vertebre 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. Conrap. 
1. Professor Johnson’s Analyses of Anthracite and Iron Ore.—In 
the Journal of the Franklin Institute, November, 1839, 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 Creek, 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 arclonieni aceount 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. gray. 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, 5.063100. 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.
