EDITORIAL STATEMENT. 
In presenting the Fifth Volume of the Bulletin to the public, it 
has been our intention to bridge over, as far as possible, the break 
which is the result of the change in the administration of the Geological 
and Natural History Departments. We take this opportunity to thank 
those who have contributed to our museum and otherwise encouraged 
the work of the departments. Obligations are expressed : To Prof. 
B. F. McKibben, for a collection of Lower Silurian fossils; to Mr. E. 
Clark, for a collection of minerals and lithological material from vari- 
ous points in the Rocky Mountains ; to Mrs. Delano, for a large col- 
lection of shells, star fishes and numerous other zoological specimens; 
to C. J. Herrick and W. H. -Cathcart, for much time and labor spent 
in identifying, labeling and arranging the Herbarium ; to Prof. C. L. 
Herrick, for a large collection of minerals ; to numerous scientific so- 
cieties and persons who have contributed to our library ; to others who 
have aided in various ways the work of the departments, but whose names 
may not appear, caused by change of the administration. We pub- 
lish elsewhere the list of those persons and societies which give equal 
exchange of publications, but would ask the pardon also of any who 
may have been omitted from this list by mistake. As this issue is 
supported entirely by voluntary contribution we would mention our 
indebtedness for the larger part of the means to Hon. E. J. Barney, 
Hon. J. B. Thresher, Hon. E. M. Thresher, Hon. Albert Thresher, 
of Dayton; Prof. C. L. Herrick, of University of Cincinnati; Prof. 
A. D. Cole, Prof. G. F. McKibben, Prof. H. L. Jones and Prof. W. 
H. Johnson, of the Denison Scientific Association. We would also 
thank Prof. C. L. Herrick for his aid in planning the work and read- 
ing some of the proof sheets. 
It is hoped that this volume will partly represent the original plan 
of the publication and that its scope may be extended as larger means 
are provided for the work.
