of the Country around Licerpool. 567 



Not much has been added to our knowledge of the local Coal- 

 measures, the Permian, and the Banter Sandstone. Permian fossils, 

 however, have lately been found by Mr. E. Dickson at Skillavv 

 Cloiigh, near Parbold, namely : GerviUia aiitiqiia, MijtUns Kquamosun, 

 Fleiirophorus costntm, ScJtizodus ohscnrus, and S. rutnndatus in the 

 l)ur|)le shales, and S. Schlotheimi in the limestone; thus adding to 

 tlie late 'Sh: E. W. liinney's fossils from the same limestone, and 

 coiifirming Dr. E. Hull's discovery of the Formation in that district. 



The Eed Keuper Marl has been proved to have a much greater 

 thickness tlian was formerly supposed, being 1,000 instead of 400 

 feetj the whole thickness of the Liverpool Trias is now calculated at 

 3.350 feet (p. 297). In the equivalents in Cheshire of the Bunter 

 Pebble-beds of the ]\Iidlands, the pebbles occur only scattered in the 

 lower GOO feet, and are altogether absent in the upper -100 feet. 

 Hence these cannot be well termed Pebl)le-beds ; and Mr. Morton 

 has replaced that name, as far as his district is concerned, by the 

 " Ui)per " and the '• Lower Hard Sandstone." 



At l.idston. in Wirral, a boring has been made to the depth of at 

 least 2,SoO feet ; but the characteristics of the several strata are not 

 known, the i)articulars having been withheld by the promoters. 

 Some brine was met with, but no coal, though it was expected to 

 have been found at 2,000 feet, according to the calculated thickness 

 of the Triassic beds in the locality. Probably a local depression 

 of the Coal-measures was met with there. 



At page 299, Mr. Morton explains that he has now reason to 

 believe in there being six kinds of fossil footprints in the Keuper 

 Sandstone at Storeton and elsewhere, which he here names, describes, 

 and figures, namely : — 



Chelone rotundatn, ]\Iorton, pi. xii, fig. d. 



Clieirotherinm (known also as Labyrinthndon and Cheirosnnrm) 



Storetonense, Morton, pis. viii-xi. 'J'he trail of the animal's 



tail [or body (?)] is figured on pi. xxii. 

 C. minus, Morton, pi. xxi, figs, a and b. 



lilii/uchosnunis articeps, Owen, pi. xii, fig. a (three largest). 

 It. viininiHs, Morton, pi. xii, fig. c. 

 B. tumidus, Morton, pi. xii, fig. a (two smallest). 



Uquisetites Keuperina, Morton, p. 115, pi. xii, fig. /, is another 

 fossil named by Mr. Morton. It was determined by Mr. F. M. Webb 

 in or before 189 L 



Lists of characteristic fossils are given for the different formations 

 successively described in detail, with the necessary sections, from the 

 lowest upwards, throughout the volume. This book is invaluable 

 to those who have, either persistently or incidentally, to study the 

 physical features, the geological structure, the products, and the 

 capabilities of the country. The changes which the surface, from 

 the earliest times, whether along the coasts, or in the river-valleys, 

 or on the more elevated grounds, has undergone from the action of 

 the air, water, or ice, enlarge the field of inquiry for the physicist ; 

 and their study is a source of pleasure to the scientist, whether 

 professional or amateur.
