Organic Remains. — My attention having been directed by Mr. 

 Prestwich to the above-named locality, I went to Salisbury and 

 spent several days there, during which I received every assistance 

 from Mr. Harding, the proprietor of the pit. The freshwater-shell- 

 bed is 1 foot 6 inches thick, and is composed of calcareous matter 

 and fine sand, the latter insoluble in acids. I could not well ascertain 

 the order in which the shells lie. They are perfectly white, and the 

 land and freshwater shells are apparently intermingled. The condition 

 of some of the very thin, delicate shells, such, for instance, as Pisidium, 

 Ancylus^ and others equally thin and fragile, would indicate that 

 they cannot have been drifted far. Many of the shells are as perfect 

 as when living, and as much so as the shells from the Copford or 

 Clacton freshwater deposit, where the shells are lying about appa- 

 rently where they died. There are, however, fragments of shells 

 in greater number at Fisherton. It is difficult, therefore, to say, 

 until further investigation is made, how far the fossils of that bed or 

 beds have been drifted, or whether they have been drifted at all.
