on the surface of a raised Beach near Plymouth. 543 



Lastly, Mr. Strickland notices the occurrence of precisely analo- 

 gous bone-beds in the Upper Ludlow rock, described by Mr. Mur- 

 chison in the ' Silurian System' (p. 198), and in Caldy Island, near 

 the junction of the carboniferous limestone with the old red sand- 

 stone ; and he offers some remarks on the bone-beds being found in 

 all the three cases near the passage from one great geological system 

 of rocks to another. 



January 5, 1842. — " A Notice on the Fossil Bones found on the 

 surface of a raised Beach at the Hoe near Plymouth," by Edward 

 Moore, M.D., F.L.S., was. first read. 



At the Meeting of the British Association at Plymouth, Dr. 

 Moore read a paper on the same subject as that which forms part of 

 the present communication*. In this notice he first alludes to the 

 discovery of the beach by the Rev. R. Hennah in 1827f, and to 

 Mr. De la Beche's account of numerous anciently raised beaches in 

 Devon and Cornwall J ; he then briefly describes the characters of 

 the beach, its position in a hollow in the limestone rock, 100 feet 

 wide, 70 feet deep, and, at its base, 35 feet above the present high 

 water mark. He also notices a projecting ledge of limestone stretching 

 several hundred feet southward from this spot, and which sustained a 

 mass of sand, with rolled pebbles and blocks, some of them two or 

 three feet in circumference, and forming a hill twenty to twenty-five 

 feet high, containing patches of loose sand with fragments of Patella 

 and Buccinum. It was, says the author, easily traced by several 

 patches along the rocks, and proved, by its structure and contents, 

 to be a continuation of the same beach. Dr. Moore likewise briefly 

 describes another deposit 100 yards westward of the beach, and at a 

 greater elevation, being 88 feet above high water, 50 feet in extent, 

 and 10 in thickness, covered irregularly by soil. 



The animal remains more particularly enumerated by Dr. Moore 

 consist of a molar and part of the jaw of a young elephant ; a femur 

 of a rhinoceros ; maxillary bones of a bear, with the malar and pala- 

 tine processes, and two teeth in each ; an entire right lower ramus 

 with teeth and tusks, the latter much worn ; four separate tusks ; 

 several fragments of long bones ; fragments of jaws of the horse con- 

 taining teeth, numerous loose teeth, portions of long bones, and two 

 caudal vertebrae ; likewise portions of a deer's jaw containing teeth. 

 The quantity of the bones which has been found is stated to be equal 

 to several bushels. The vertebrae of a whale, much rounded, were 

 also discovered, with undeterminable portions of ribs. The animals 

 to which the above remains belonged, are considered by Dr. Moore 

 to have coexisted with those which inhabited the caves of Devon- 

 shire. 



The author then enters upon a defence of the opinions contained

 ciation for 1841, Trans, of the Sections, p. C2 (published 1842).
