caribbceum. Associated with this supposed Eozoon, the author has 

 found other remains. These include fragments of coral, some of 

 which are stated to resemble Favosites, although no pores or 

 tabulae could be detected in them. These fragments are thought 

 by the author to have belonged to a minute branching Favosites, 

 which he proposes to name F. fenestralis. Plates and stems of 

 Echinoderms are scattered through the rock. The author par- 

 ticularly described a specimen consisting of 5 ambulacra! plates, 

 with 4 pairs- of pores, and another fragment showing portions of 

 at least 20 ambulacral or pseudo-ambulacral plates, reminding one 

 of those of the Devonian Eleacrinus. The author has found that 

 the bands of calcareous matter interstratified among the slates are 

 seldom devoid of organic remains, except when they are very 

 highly metamorphic. In a finely laminated limestone he found 

 great abundance of obscure fossils, many of which appeared to be 

 remains of Oystidea, whilst others resemble annelid-tubes, like 

 Salterella. The author suggested that the function of Eozoon in 

 pre-Cambrian times was auologous to that of corals at subsequent 

 periods. He considered that there is the highest probability that 

 the Caribbean series will ultimately prove to be pre-Silurian. 



In the discussion which followed the reading of this paper, Dr. 

 Carpenter, from the slight examination he had been able to make 

 of the fossils, was unwilling to speak decidedly about them. 

 There was, however, no doubt of numerous organic remains 

 occurring in the rocks, and among them serpuline shells and 

 echinoderms. As to the supposed Eozoon, he had not been able 

 to recognize any of the characteristics of that fossil ; and by treat- 

 ing the Trinidad specimens with acid he found no traces of struc- 

 ture left, and yet there had not been sufficient metamorphism to 

 destroy other organisms. In some dredgings from the ^Egean 

 Sea he had found fragments of echinoderms and other organisms, 

 in which a siliceous deposit had replaced the original sarcode in 

 the same manner as had occurred in the Canadian Eozoon, thus 

 proving the possibility of this form of constitution, which had been 

 warmly contested. Quar. Jour. OeoL Soc., xxvi.'*(1870), pp.

Evidences of Recent Changes of Level on tlie Mediterranean 

 Coast. Mr. (r. Maw presented a paper with the above title at 

 the Liverpool meeting of the British Association. He described 

 the structure of the coast, the general absence of the sea-cliffs 

 within the Straits of Gibraltar, clue to the shelving contour of the 

 land under the sea. He considered the inset current from the 

 Atlantic as indicating a general subsidence of the whole Mediter- 

 ranean basin; Sir Charles Lyell, however, considered that the 

 outward current balanced the inward current, and that therefore 

 this evidence of submergence was of no weight. Mr. Maw 

 alluded to the submarine springs passing through channels of sub- 

 aerial origin occurring in the coast caverns, and considered this
