have been found in the cave-earth, but nothing of the kind in the 

 breccia. That the implements of the breccia are of earlier date than 

 those of the cave-earth is certain ; that they belong to a ruder age may 

 be inferred. Great as may be the antiquity of the cave-earth men, 

 that of the breccia men must be at least double. W. T.

 glacial period, and the theory of evolution. W. T.

Ramsay, Prof. A. C. On the Comparative value of certain geological 

 ages (or groups of formations) considered as items of Geological 

 Time. Proc. Roy. Soc. vol. xxiii. p. 334. 

 The Cambrian and Silurian may be divided into three groups, sepa- 

 rated by unconformities, and each characterized by a fauna of its own. 

 The Devonian may also be divided into three groups, each characterized 

 by a fauna of its own. On these grounds the author thinks that the 

 time occupied in the deposition of the Devonian rocks may have been 

 as long as that occupied in the deposition of the Cambrian and Silurian 

 together. Again, the Jurassic, Neocomian, and Cretaceous formations 

 form a similar threefold group, which may be comparable either with 

 the Silurian or Devonian trilogy. The Carboniferous is then correlated 

 with the Eocene, the Permian with the Miocene, and the Trias with 

 the Pliocene, on the strength of sundry resemblances in the conditions 

 under which they were formed ; and thus the conclusion is arrived at 

 that the great local continental era, extending from the beginning of 

 the Old Red Sandstone to the end of the Triassic period, is comparable 

 in point of time to all the time that has elapsed from the beginning of 

 the Lias down to the present day. Considerations follow tending to 

 the same conclusion from a pala?ontological j)oint of view. A. H. G.
