the species selected for illustration are from the Silurian rocks of 
America, two are from Europe, and about four from Britain. 
The series of well-executed woodcuts and plates illustrating the 
microscopic structure, copied from sections and drawings prepared 
by the author himself, together with the clear and elaborate deserip- 
tions, will render this work a valuable guide for future observers on 
a puzzling group of Paleozoic corals; for, as Prof. Nicholson 
observes, the subject is far from exhausted. ‘he main object has 
been to record the characters of a number of partially known forms 
rather than to describe new species—a laudable object in the 
present state of Paleontology, where in certain groups, such as that 
now under consideration, the identification and recurrence of species 
in particular horizons are chiefly based on the characters of external 
form and aspect.

Amone the various contributions to geological literature, scarcely 
any having a similar object and tendency to the above work have 
appeared, excepting the ‘Sections and Views illustrative of Geolo- 
gical Phenomena,’ by De la Beche, published in 1830. 
The facts collected in this volume embody the results of visits to 
some of the more interesting geological localities in this country and 
on the continent during the last fifty years; and the sketches and 
diagrams made on the spot are now given in more than two hundred 
plates with ninety pages of descriptive letterpress. The author has 
endeavoured to make the description of the sections and sketches as 
brief as possible—in fact, to let the sketches speak for themselves, 
so that any one with a geological eye will at once see why the section 
or sketch was drawn. 
Among the various subjects illustrated we may notice the Lias 
and Trap rocks of Portrush, the chalk and basalt of the Giant’s 
Causeway, the extinct volcanos and crater-lakes of the Eifel, the 
granite rocks of the Land’s End, the parallel roads of Glenroy, 
various sketches of the Silurian, Devonian, and Carboniferous rocks, 
the moraines and glaciers of the Alps, the scenery and rocks of the 
Auvergne, the physical and geological features around Rome and 
Naples, the geological structure of parts of Sweden and Denmark, 
the contours produced by the weathering of different kinds of rocks. 
Considering the range of time through which the work extends, 
one or two of the earlier descriptions might now perhaps be slightly 
modified and improved; among the later ones a further and more 
detailed account of the Faxoe beds would have been interesting, in 
showing the nature and relation of the strata and their fossils, of 
the Stevensklint and Faxoe limestones to the underlying white chalk 
with flints. 
There appears to be some confusion about the crustacean figured 
on plate 204, from the Lower ‘Greensand of Atherfield, and referred 
to Mecochirus Pearcei, M‘Coy ; the latter species is from the Oxford
