form of published papers and reports, our material accumula¬ 
tions 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 adequately to represent the ideals of 
the Station management or to illustrate its final ends. Never¬ 
theless, considerable contributions 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 embodying the results of their investiga¬ 
tions, 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 entomology 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 
oligochsete worms have appeared as two papers of the Laboratory 
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 by Mr. W. H. Ashmead, 
of the United States National Museum, on parasitic Hymenop- 
tera bred from aquatic insects at Havana, containing descrip¬ 
tions 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 descriptions of a new genus and two 
new species of oligochaete worms from Havana, and of one new 
species from Florida, together with a description of the reproduc¬ 
tive organs of Pristina, upon which subject nothing has heretofore 
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 student of the University, is also in press. 
This article has been made to include the product of a careful
