Dr. Hanckel's plantation I had good opportunity of examining these fragments; and at Drayton Hall they have been gathered from the lawn and thrown into heaps." Professor Tuomey goes on to state that, though at first disposed to refer these fragments to a different formation from the underlying marl, he had found that nearly all the fossils were common to both, and concluded that the fragments were only the surface of the marl torn up and scattered. He concluded, also, that the dispersion of the fragments was of comparatively recent occurrence, and was probably due to the recession of the waters of the ocean at the time of the elevation of the Post Pleiocene to its present level. He says in continuation; "I have more than once alluded to the removal, by solution, from calcareous rocks, of a portion or all of the lime. This has taken place, to a great extent, in the beds under consideration. In many instances there is little more left than the silica and alumina of the marl, with a trace of lime; and the latter ingredient rarely exceeds 6 per cent." In making this statement Professor Tuomey doubtless had in mind the marl analyses of Ruffin, which he quotes further on in his report, particularly that of the "lumps of stony hardness," previously alluded to in the present article, when speaking of Ruffin's work. By the term "lime," also, he doubtless meant carbonate of lime. Tuomey evidently did not suspect the presence of phosphoric acid in the lumps in question, doubtless misled by the fact that, while he was aware that the agricultural value of the marls was enhanced by the presence of the phosphate of lime which had been shown to exist...
