INTRODUCTORY. 



In submitting the subjoined Preliminary List of 

 Fossil Elephant and Mastodon Remains in Illinois and 

 Iowa, which is believeS to be the first of its kind in 

 these states, the compiler does not intend to imply 

 that the list is nearly complete ; she is impelled to pub- 

 lish the result of her research, thus far, in the hope that 

 such a list may be of assistance in securing further 

 data along this line. The difficulty in securing reliable 

 information can be easily appreciated, for compara- 

 tively seldom does the working Geologist see such re- 

 mains in situ, and the museums, their ultimate reposi- 

 tories, appear to keep scant record of the circumstan- 

 ces connected with such finds, their geographical and 

 geological position, date of their discovery, etc. 



In presenting this list the compiler would therefore 

 make her humble plea for more complete and more 

 carefully kept data from which the specialist must pro- 

 ceed in determining more nearly the true horizon of 

 these huge Proboscidians. She also wishes to express 

 her gratitude to the State Geologists and Assistants, 

 to Librarians, Curators of different museums, and to 

 numerous private' individuals, all of whom have so 

 cheerfully assisted her, and in particular to Dr. J. A. 

 Udden, of Augustana College, does she feel indebted for 

 invaluable assistance and encouragement.
