REVIEWS. 301 
The geological survey of Illinois was inaugurated by vote of 
the Legislature in 1851, and was continued for several years with- 
out any very important results having been made public. Soon 
afterwards a strong opposition was made to the survey, but thanks 
to the stand taken by the Hon. Richard Yates, at the time Govern- 
or of the state, a bill discontinuing the survey was vetoed, and 
in 1858, Mr. Worthen was appointed by Governor Bissell as State 
Geologist, and from that date the survey has had the continued 
and liberal support of enlightened legislators, Mr. Worthen being 
thus enabled to furnish a series of volumes that will rank second 
only to those of the New York survey, which has been contin- 
ued for so many years, and has embraced the kindred departments 
of Zoology and Botany. May we not hope that Illinois will 
also continue her survey until not only her geology and palæ- 
ontology are thoroughly reported on, but her Zoology and Botany 
as well, and a State Museum established that will have within 
its walls a complete representation of the Natural History of 
the state. Alas that the building for such a museum was delayed 
a moment after Mr. Worthen had called attention to its necessity 
in his first report, for his fears have proved true, and the fine 
museum of geology and palzontology which had been brought to- 
gether by the survey has been, since the publication of the last 
volume, subjected to the fate that sooner or later seems to be the 
destiny of all museums not placed in fire proof buildings. 
The first volume of this survey was published in 1866 and con- 
tains a general account of the geology of the state. 
The second volume, published in the same year, is devoted to 
the paleontology, and has fifty plates on which are figured several 
hundred species of fossils. Especially important is this volume 
to the student of the fossil fishes and plants of our Coal Measures, 
in which the strata in Illinois are most remarkably rich. 
The third volume of the survey, published in 1868, contains a 
continuation of the detailed geology of portions of the state, and 
description of many more fossils, illustrated by twenty plates and 
many cuts. 
The fourth volume, published late in 1870, contains first a con- 
tinuation of the special geology of thirty-three of the counties in 
the state, by the Director of the survey and his assistants, Messrs. 
Bannister, Bradley and Green; and secondly, the continuation of 
the palzontology of the state, in two sections; first, the fishes by
