for two of the summer months of 1895 by !Mi'. Ernest B. Forbes. Mr. Hart's 

 share in tlie regular routine of Station opei-ations has been the making of the 

 inshore and longshore collections at the various substations. In addition to 

 his studies of the habits and life histories of aquatic insects, he has listed 

 the Mollusca of the collections from the beginning. From September 8, 

 18!)4, to July 1, 1895, he was the sole continuous occupant of the Station, 

 being responsible during that period for the regular field work, canned on 

 with the assistance of visiting parties from the State Laboratory at Urbana. 



Mr. Adolpli Henipel was engaged withox;t interruption upon a study of the 

 Protozoa and Rotifera of the Station from its opening to Jime 1, 1896. At 

 this time the condition of his eyes forbade further iise of the microscope and 

 he was placed in charge of the Station launch as its licensed engineer. He 

 occupied the Station alone during the winter of 1895-96, keeping up, with 

 such assistance as it was necessary to engage from time to time, the regular 

 routine of collections and observations at the various substations. 



Miss Lydia M. Hart, Artist of the State Laboratory, has devoted a large 

 part of her time to drawings in illustration of the various papers prepared by 

 the Station force. She was at Havana during about a month of 1895, the 

 remainder of her work in this direction having been done at the State Labora- 

 tory. 



Mr. Ernest B. Forbes has served during the vacation period of three seasons^ 

 the first as a general zoological assistant, the second as an assistant in the 

 entomological field work, and the third in making a special studj- of the 

 Cyclopida^ of the Station collection. 



Periodical chemical analyses of various waters collected at the Station have 

 been made, from the first opening, under the direction of Professor A. W. 

 Palmer, of the chemical department of the University of Illinois. Mr. C. F. 

 Hottes, Botanical Assistant in the University, made several trips to the Station 

 with Superintendent Smith during his regular visits in the winter of 1894-95 

 and both he and Professor T. J. Burrill, of the University department of 

 botany, have made occasional collections of aquatic plants. 



Mr. Miles Newberry, an experienced fisherman of Havana, has served the 

 Station veiy efficiently from the beginning as a general assistant. He has 

 been particularly serviceable as an aid in plankton work and has had imme- 

 diate charge of the boat and of the aquatic equipment generally. 



GENERAL EXHIBIT OF RESULTS. 



Although the first report of results accomplished in a field so extensive and 

 complicated as that occupied by our Biological Station must necessarily be 

 largely an exhibit of work in progress, it seems possible to make a statement 

 which shall give a comprehensive, if somewhat indefinite, idea of the outcome 

 of operations thus far undertaken. This report uuiy be made most conven- 

 iently under the heads of plankton operations, collections accumulated ento-
