recent 'deposits. The coal-seams, of which numerous sections are given, 
vary in number, thickness and character, in the different counties ; one seam, 
the “ block coal,’’ has a great reputation for smelting iron ores, and is also 
in great demand at Chicago, Louisville, Cincinnati, and other places. 
Parke county appears to expose almost a complete series of the regularly 
recognised coal-seams found in the State ; these alternate with beds of shale, 
clay, sandstone and limestone, sometimes full of marine remains, and many 
identical with species of Brachiopoda and other mollusca characteristic of 
British carboniferous limestone, showing, as in our coal-fields, intercalations 
of marine remains with a land vegetation; although Professor Collett 
remarks in the Report on Dubois county, The internal evidence recorded 
by either the coal or the limestones considered separately, shows facts which 
can scarcely be harmonized with the adopted ‘ bog or swamp ’ theory for 
the deposition of coal and coal-measure limestones.” The prevailing rocks 
of Dearborn, Ohio and Switzerland, are chiefly lower Silurian, the upper 
Silurian occupying small areas in the north-west parts of the last two 
counties,^ more or less drift being found on all the high land. 
There is an interesting Report by Professor Cope, on the Wyandotte 
cave, which traverses the St. Louis carboniferous limestone of Crawford 
county in south-western Indiana, and which seems, from its extent and 
stalactites, to be as well worthy of popular favour as the Mammoth Cave 
in Kentucky, with the fauna of which the life of the Wyandotte cave has 
much resemblance ; of sixteen forms noticed the genera are identical, and 
one, the blind fish Amhlyopsis spaleus, is the same in both caves. 
The concluding chapters contain papers on the Meteorology of Switzer- 
land county by C. B. Boerner, and on the manufacture of Spiegeleisen by 
Hugh Hartmann. 
THE SEA AND ITS WONDERS.* 
I F anything were wanting to assure the publishers of this book that it 
has met the wants of the general public, assuredly it must have been 
met by the demand for a fourth edition. Indeed the fact is almost sur- 
prising, the more so when we remember that] the book made its first 
appearance little more than a dozen years since. And it is equally 
astonishing from the fact that many and infinitely superior books have 
been for a vastly longer period in their first and only issue. This of course 
maybe intelligible enough if the explanation be offered that the entire 
number of volumes in each edition was something extremely small ; other- 
wise, in our opinion, it is a singular and remarkable circumstance. For the 
book is simply an enlarged zoology, to which has been added a certain 
amount of lore anent the ancient discoveries of the continents and islands 
which now form our globe. Furthermore, the illustrations are, with the 
exception of a few page-plates, of the worst possible description. They are
