PREFACE. 



AT the 1898 winter meeting of the Ohio State Academy 

 of Science, Mr. Emerson E, McMilHn, already a life 

 member, through Professor W. R. Lazenby, tendered 

 the Academy the sum of $250.00 to be expended by the 

 trustees in furthering original scientific researches in 

 Ohio. The donor placed no restrictions upon the use of 

 this fund except to express a desire that, so far as possible, 

 it be used in aiding those who are competent and willing to 

 give their time, but unable to contribute their expenses while 

 employed in their researches ; thus giving aid to such inde- 

 pendent workers as lacked the necessary financial resources. 

 Among the grants made by the trustees during 1899, from 

 this fund, were $50.00 each to Professors Tight and Bow- 

 nocker, and $10.00 to J. H. Todd, M. D., for the purpose of 

 aiding them in studying the Preglacial Drainage of certain por- 

 tions of Ohio. From this fund for 1900, Mr. Gerard Fowke 

 was granted the sum of $25.00, for a similar purpose. The 

 results from the work prosecuted under these grants are here- 

 with transmitted as No. 3 of the Series of Special Papers. Mr. 

 Fowke has kindly consented to prepare an introduction, giv- 

 ing a short review of work previously done along this line of 

 research in Ohio. The map facing preface illustrating the pre- 

 glacial drainage of the entire State, so far as it has been worked 

 out, has been prepared by Professor Tight. 



The expense of publication has also been taken from Mr. 

 McMillin's research fund, which he has been kind enough to 

 continue for 1900. 



Professor Raymond Osburn was granted $50.00 in 1899 to 

 aid in the study of the fishes of the State, and a similar sum was 

 granted him in 1900. The results of Professor Osburn's re- 

 searches are being prepared for publication and will constitute 

 No. 4, of this series, and will be issued early in 1901.
