An account of the Fossil Organic remains of the southeast 

 coast of Cornioall and of Bodmin and Me?iheniott, by C. W. 

 Peach. — The line of coast examined commences at Veryan, four 

 miles south of Tregoney, and extends eastward by Gorran, the 

 Blackhead, and Fowey, to East'Looe. The cliffs are composed 

 throughout of quartzose and slaty rocks, hitherto supposed by Mr. 

 Conybeare and others to be destitute of fossils. But along the 

 whole line, Mr. P. has detected traces of Brachiopodous shells and 

 corals, 'and the stems of encrinites are of frequent occurrence. 

 From Veryan to Gorran the quartzose rocks rarely contain traces 

 of shells, but in the calcareous slates in contact with dykes of 

 greenstone at Blackhead, remains of corals resembling Turbino- 

 lepsis, and of the genera Cyathocrinus, Spirifera, and Orthoceras 

 occur. Eastward, at Pridmouth, a fine specimen of the Platy- 

 crinite was found, with the column, pelvis, arms, &c. In the 

 slate quarries of Fowey, remains supposed to be those of fish, 

 and corals of the genus Favosites were detected. Near Polman, 

 occur encrinital stems nearly a foot long, together with remains 

 of trilobites, corals of the genera Cyathophyllum, and Favosites, 

 Spirifers, Orthoceras, and a fossil with a structure resembling that 

 of the Sepiadas. At Pentlooe, an equal-valved bivalve, resem- 

 bling Uncula, and a species of Orthis, have been found ; and at 

 East Looe another fine specimen of an encrinite, with column, 

 arms and tentacula attached; also specimens of Cyathocrinus, 

 Fenesiella, Turbinolopsis and Orthis. At Bodmin, the author has 

 detected encrinites in the slate quarries, and in those of Menhe- 

 niott in Liskeard the eye of a trilobite in good preservation. On 

 the beach below the cliffs at Port Mellin, near Mevagissey, the 

 author observed traces of a lacustrine deposit, containing roots 

 and branches of trees, and the elytra of beetles, exposed after a 

 heavy gale. 



A letter was read from Mr. T. B. Jordan, of the Museum of 

 Economic Geology, on copying Fossils by a galvanic deposit. — 

 In applying the method ordinarily used in electrotyping, some 

 difficulty was experienced by the author in consequence of the 

 irregular form of the fossils, parts of which would not relieve 

 from the wax or plaster matrix in which the copper is afterwards 

 deposited. Mr. J. therefore adopted a compound of glue and 

 treacle, (used by printers for their inking rollers,) as the material 

 of the moulds, the elasticity of which admits of its leaving the
