1879. } Recent Literature. 645 
counties, with a general survey of the geology of the State, and 
special reports on the economic geology. Considerable space is 
given to palzontology, Mr. S. A. Miller contributing a catalogue 
of fossils found in the Hudson river, Utica slate and Trenton 
groups, as exposed in the south-east part of Indiana, south-west 
part of Ohio and the northern part of Kentucky; while Prof. J. 
S. Newberry supplies a list of certain sub-carboniferous fishes, 
with descriptions of several new species; among them teeth 
much like those of the living rays, especially Myliobatis, the writer 
expressing “little doubt that they represent the oldest and most 
gigantic members yet known of the ray family.” A good deal 
of space is devoted to the archeology of the State, but the chief 
interest of the report lies in the full account of the famous Wy- 
andotte cave, illustrated by alarge map. The geology and topog- 
raphy of the cavern, with adjoining caves, is given in detail, and 
for the first time we have mapped out one of the largest and most 
beautiful grottoes in the world. On one of the maps illustrating 
the reports is laid down the position of the numerous caves 
occurring in the subcarboniferous limestone called the St. Louis 
or cavernous limestone. Appended are Prof. Cope’s observations 
on Wyandotte cave and its fauna, revised for this report. 
Hyartt’s Common Hynprorps, CORALS AND EcHINODERMS.!—This 
is the fifth brochure of the series of Guides for teachers of sci- 
ence in schools. It is intended to supply such information as 
they need in teaching and are not likely to get from other 
sources. The style is clear and attractive, and the illustrations 
fresh and good enough for the purpose, and some of them drawn 
by Mr. Van Vleck for the book. In this connection we may 
draw attention to what was done the past winter by the Boston 
Society of Natural History, through its custodian, Prof. Hyatt. 
t was found in October that the assistance of the society was 
was resolved to institute appropriate courses of lessons for the 
teachers, if the means of paying expenses could raised by 
donations. The necessary funds were secured by two ladies who 
are members of the society, which may congratulate itself upon 
such evidence of the activity and usefulness of this new class of 
its members. Fortunately for their success, these ladies met with 
appreciation from Mrs. Augustus Hemenway, without whose 
assurances of support and interest the society would not have 
dared to begin these courses at an estimated cost of three thou- 
sand dollars. Many of the schools contributed, in varying sums, 
to the amount of seven hundred and twenty-six dollars. The
