_ for two of the summer months of 1895 by Mr. Ernest B. Forbes. Mr. Hart’s 
‘share in the regular routine of Station operations has been the making of the 
ashore 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 
1894, to July 1, 1895, he was the sole continuous oceupant of the Station, 
being responsible during that period for the regular field work, carried on 
with the assistance of visiting parties from the State Laborator y at Urbana.

Mr. Adolph Hempel was engaged without inter ruption upon a study of the 
Protozoa and Rotifera of the Station from its opening to June 1, 1896. At 
this time the condition of his eyes forbade further use 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 abr iees 
Miss Lydia M. Hart, Artist of the State Laboratory, has devoted a large 
part of her time to dr awings 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 zoélogical assistant, the second as an assistant in the 
entomological field work, and the third in making a special study of the 
Cyclopide 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 Univer sity, 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 
Biation very 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 aé¢complished 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 outeome 
‘of operations thus far undertaken. This report may be made most conven- 
dently under the heads of plankton operations, collections accumulated ento-
