and the manner in which the perpendicular joints, the stratiform beds, and the 

 spheroidal structure combine to produce the tors and rocking-stones, and the 

 most characteristic features of the moor. 



In conclusion, the author said that he had not seen any glacial markings on the 

 Dartmoor granite, but that Professor Otto Torrell, when visiting the Moor with 

 him last autumn, gave an unqualified opinion that many of the gravels were the 

 remains of moraines. 



Notice of the Discovery of Organic Remains in the Rods hetiveen the Nare Head 

 and Porthalla Cove, Cornwall. By C. W. Peach, A.L.S. 



In May last, after assisting to arrange a collection of Cornish fossils in the new 

 Museum of the Geological Society of Cornwall, at Penzance, the author examined 

 there the interesting series of the rock specimens of Cornwall, made by Dr. Boase 

 many years ago, to see whether any of them contained organisms. One of them, a 

 dark limestone, marked 733, from Porthalla Cove, attracted his attention ; it evi- 

 dently contained organisms which were so indistinct that they had hitherto escaped 

 notice. 



The authorities kindly had it rubbed down and polished, and thus Encrinites and 

 a coral, probably Favosites pohpnorpha, were well shown. 



Owing to this interesting discovery, the author resolved to visit the spot and to 

 try to find the rock in situ. He met with a few specimens of blackened remains, 

 enclosed in a dark slaty rock, between tide-marks, in Nelly's Cove, called " Betsey's 

 Cove " at page 95 of the ' Geology of Cornwall, Devon, &c.,' by the late Sir Henry 

 De la Beche. One of the specimens shows one septum of an Orthoceras and part of 

 another. The others are evidently portions of organisms. Similar blackened 

 Orthocerites, Szc. are not imcommon in a similar kind of rock at Fowey, Polruan, 

 &c. ; many such obtained there by the author are in the Museum at Penzance. 

 Those from Nelly's Cove are to be added to them. 



On the alleged occurrence of Hippopotamus major a7id Machairodus latidens 

 in Kent's Cavern. By W. Pengellt, F.R.S., F.G.S. 



The author, having reminded palaeontologists that Prof. Owen (Brit. Foss. Mam. 

 &c. pp. 410 and 175, &c.) had mentioned Hippopotamus major and Machairochis 

 latidens as having been found in Kent's Hole, and that the late Dr. Falconer had 

 not been convinced that either of them had been met with there, proceeded to give, 

 in each case, a brief summary of the evidence furnished, first, by the published and 

 impublished statements of the early explorers of the Cavern, Mr. Northmore, Mr. 

 (now Sir) W. C. Trevelyan, Rev. J. M'Enery, Rev. Dr. Buckland, and Mr. God- 

 win-Austen ; secondly, by their figures of the specimens they found ; and, thirdly, 

 by the specimens themselves. 



The following are the chief conclusions at which he anived : — 



1st. That there is no trustworthy evidence that Hippiopiotamus major had been 

 found in the Cavern. 



2nd. That Mr. M'Enery found five canines of Machairodus latidens there. 



3rd. That at present one of the five is in the British Museum, one in the Museum 

 of the Royal College of Surgeons, one in the Museum of the Geological Society of 

 London, one in the Oxford Museum, and one in the private collection of Sir W. C. 

 Trevelyan. 



Source of the Miocene Clays of Bovey Tracey. 

 By WiniAM Pengellt, F.R.S., F.G.S. 



In this communication the author stated, in reply to some remarks by Mr. Maw 

 (Quart. Joum. Geol. Soc. vol. sxiii. pp. 392-393, 1867), that he had been led to the 

 conclusion (Phil. Trans, part ii. 1862, p. 1027) that the clays in question were 

 derived from the degradation of the Dartmoor granite, by the following facts : — 



First, the proximity to Dartmoor ; secondly, tliat all the beds of clay and of sand 

 thin out eastward, that is, with increased distance from Dartmoor; thirdly, the beds
