Analysis of Scott Spring. — Skeleton of the Zygodon. 409 



Art. XVII. — Analysis. of the Scott Spring, Scott County, Vir- 

 ginia; by C. B. Hayden, of Abingdon, Va. 



The uniform temperature of this spring, (G8£°,) fifteen or six- 

 teen degrees higher than the average temperature of the springs 

 of the vicinity, classes it among the thermal waters, and renders 

 it a natural medicated warm bath, subserving ah the purposes of 

 health and luxury, without being sufficiently high to impart to it 

 the usual disagreeable flavor of warm waters.

Art. XVIII. — Notice of the Discovery of a nearly complete Skeleton of 

 the Zygodon of Owen (Basilosaurus of Harlan) in Alabama ; by 

 S. B. Buckley, A. M. 



Some years ago a few imperfect vertebra? of this animal were sent 

 to Philadelphia, which were found near the Wachita River in Louisi- 

 ana. These were described by Dr. Harlan in 1834, and referred to a 

 lost genus of the Saurian order. From the great size of the bones, he 

 called it the Basilosaurus. Subsequently Harlan obtained other bones 

 of his Basilosaurus, which were found on the plantation of Judge Creagh, 

 of Clark County, Alabama, and forwarded to Philadelphia by that gen- 

 tleman. These were one or two fragments of the jaws with teeth, of 

 which the upper portion was broken off and lost, also pieces of ribs, 

 with some other long bones belonging to its paddles, and several verte- 

 brae with the processes broken off. These Harlan also described in the 

 " Transactions of the American Philosophical Society." Part of these 

 bones were taken by Harlan to London, where they were pronounced 

 by Owen, from a microscopical examination of the teeth, to belong to 

 a genus of mammalia between the Saurians and Cetacea. He named 

 it the Zygodon, in allusion to the curious form of the molar teeth.
