by assistantS/Working under his direction. Since the beginning of this work 

 it has been merged in that of a Clhemical Siir\-ey of the waters of the State 

 established at the University in consequence of appropriations made by the 

 State legislature to that end during the winter of 1895, One hundred and 

 ninety-three analyses in all have now been completed and a report setting 

 forth the comparative results will be published during the current year. 



REPORTS AXD PUBLICATIONS. 



The tinal major product of our Station work must be in the form of pub- 

 lished papers and reports, our material accumulations being of merely secondary- 

 interest and value and often of only temporary use. Necessarily, however, so 

 soon after the organization of the work, it has not been possible to prepare and 

 to publish papers of a sort adeciuately to represent the ideals of the Station 

 management or to illustrate its final ends. Nevertheless, considerable contri- 

 butions to science resulting from the investigations of the Station staff have 

 already been printed or are now in press and the preparation of manuscript 

 is going actively forward in several departments. Quite in accordance with 

 our original expectation, visiting students who have availed themselves of the 

 facilities of the Station have prepared or are now preparing papers embody- 

 ing the results of their investigations, credit for which must belong in part 

 to our establishment, without which they would not have been written. 



The principal contributions now in print are papers by Mr. Hart, Mr. Hempel, 

 and Professor Smith, The first of these is an article by Mr. Hart on the ento- 

 mology of the Illinois River and adjacent waters, filling one hundred and 

 twenty-five pages of our Laboratory- Bulletin and illustrated by fifteen half- 

 tone plates. Professor Smith's additions to a knowledge of our oligoeha?te 

 worms have appeared as two papers of the Laboratoiy Bulletin, describing 

 four new species and a new genus of these animals, with a large amount of 

 anatomical and histological detail. We have also printed an article Viy Mr. "W. H. 

 Ashmead, of the United States National Museum, on pai-asitic Hj-menoptera 

 bred from aquatic insects at Havana, containing descriptions of three new- 

 species. Four new species of Protozoa and three of Rotifera from Station 

 situations have been described by Mr. Hempel in an article of the State 

 Laboratory Bulletin, accompanied by five plates of illustrative figures. 



We have now going through the press a third paper by Professor Smith, 

 containing a description of a new genus and two new species of oligochiete 

 worms from Havana, and of one from Florida, together with a description of 

 the reproductive oi'gans of Pristina, upon which subject nothing has hereto- 

 fore been known. This article will be accompanied by four plates. A paper 

 on the Ostracoda of North America, by Mr. R. W. Sharpe. a graduate stu- 

 dent of the University, is also in press. This article has been made to include 

 the product of a careful examination of the collections made in this group 

 from the opening of the Station to the midsununer of 189(5. It is accompanied 

 by ten plates. 



Mr. Heyipel's observations on the Protozoa and the Rotifera of the Station, 

 accuinulated during two veavs' continuous studv. are in hand in the form of
