86 Geology of the South East of Dorsetshire. 



Dr. M. says he "has never heard of any fossils being found" 

 in the Swanwich Bay sands. Has he then never read Dr. 

 Buckland's paper, (G. T. vol. 3), on the discovery of the bones 

 of the Iguanodon, Plesiosaurus, Megalosaurus, and Crocodile, 

 in these very cliffs, by the Rev. Mr. Bartlett and Col. White, 

 and which I have seen in the former gentleman's museum ? 

 Has he never seen Mr. De la Beche's Geological Manual, 

 wherein are distinctly named, from Swanwich Bay, a Cardi- 

 um, a Pinna, a Venus, three species of Cyclas, a Paludina, 

 two species of Melania, and a Cypris? (2nd Ed. p. 304). — 

 Or has he never become acquainted with Dr. Fitton's learned 

 paper before alluded to ; in which he will find that the mine- 

 ralogical characters given by Dr. Fitton, are a vast deal more 

 to be depended on, than his own generalising similarities ? — 

 " In the coast section on the east of Purbeck, the whole series 

 from the chalk down to the Portland stone is disclosed : " 

 (this is represented in my fig. 35, p. 417). "The upper green 

 sand, gault, lower green sand, and weald clay, in strata highly 

 inclined, occurring in a nook or recess called Pemfield, at the 

 southern foot of Ballard Hill ; and the Hastings sands, occu- 

 pying the whole of the range of cliffs thenCe to the town of 

 Swanage, (see fig. 9) ; the section of which is so distinct, 

 that with sufficient labour all the details can be made out. — 

 The strata correspond, however, precisely with what I have 

 mentioned in the preceding account of the Isle of Wight, and 

 of the coast near Hastings, and, as at those places, consist of 

 sand and sand rock, including concretions of calcareous grit, 

 and alternating with a very large proportion of reddish and 

 greenish cohesive sandy clay. Detached portions of lignite 

 are frequent also throughout the series here. Fragments of 

 the trunks of silicified coniferous trees have been found in 

 dark brown masses ; and detached bones of the Iguanodon 

 sometimes occur loose on the shore, beneath the cliffs near 

 the town of Swanage." (G. T. iv. p. 207). 



Fragments of nearly perfect coal are also found at the side 

 of the road from Studland. 



Dr. Fitton also gives the following, (in a list of fossils) from 

 these cliffs.
