EDirORIAL STATEMENT. 



In presenting the Fifth Volume of the Bulletin to the i)ul)iic, 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 (ieological 

 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. K. 

 Clark, for a collection of minerals and lithological material from vari- 

 ous points in the Rocky Mountai;^; to Mrs. Delano, for a large col- 

 lection of shells, star fishes and numerous other zoological specimens ; 

 to C. J. Herrick and \V. 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 e«pial 

 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 

 su])j)orted entirely by voluntary contribution we would mention our 

 indebtedness for the larger part of the means to Hon. K. J. Barney, 

 Hon. J. B. Thresher, Hon. K. M. Thresher, Hon. .Mbert Thresher, 

 of Dayton; Prof. C. L. Herrick, of I'niversity 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 al.so 

 thank Prof. C. L. Herrick for his aid in i)hinning 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 scof)e may be extendctl as larger means 

 are provided for the work.
