–Pp. 116-117: {{"Dr. J. Lawrence Smith, of Charleston, S. C., made a communication on some fossil bones from the vicinity of Charleston. The bones noticed were fragments of a rib, resembling that of the Manatus, and of a marine turtle and ray. The character of [117] the formation in which they occur was described, it being that extensive calcareous bed which underlies a large portion of South Carolina and some of the neighboring states. "A discussion arose upon the geological age of the formation furnishing the specimens exhibited by Dr. Smith."}}
