A Circulatory Apparatus for keeping Aquatic Organisms under 
definite Physical Conditions.—Interim Report of the Committee, 
consisting of Mr. W. EH. Hoye (Chairman), Professor S. J. 
Hickson, Mr. F. W. KEEBLE, and Mr. F. W. GAMBLE (Secretary). 
THE apparatus has been constructed, and Messrs. Keeble and Gamble 
have used it for making an investigation on the colour-physiology of 
Hippolyte varians. It is intended to submit a full account of these 
researches at the Bradford meeting next year.

Tue table in the Naples Zoological Station hired by the British Asso- 
ciation has been granted during the past year to Dr. H. Lyster Jameson, 
of Trinity College, Dublin, the Royal College of Science, London, and the 
University of Heidelberg, who occupied it from October 7, 1898, to April 
17, 1899. He specially investigated the anatomy of certain Gephyrea 
and allied vermiform organisms, and has published a paper upon the lead- 
ing species obtained, in the Naples ‘ Mittheilungen.’ Other papers are in 
hand and ready for the printer, as set forth in his accompanying report. 
Prior to Dr. Jameson’s tenure of the table it was occupied but for a 
couple of weeks by Mr. Eliot, Secretary to the English Embassy in Con- 
stantinople. Mr, Eliot commenced work upon the Mollusca, with a view 
to certain economic considerations, but did not carry his enquiry far 
enough to justify the presentation of a report. 
Your Committee have been informed by the resident officials at the 
Naples Zoological Station that the numbers of investigators who yearly 
make use of the institution are steadily on the increase, and that the 
material sent out during the year to workers and centres of instruction 
and research in all parts of the world has been greater than on any pre- 
vious occasion. They would direct attention to this proof of the increas- 
ing utility of the Naples station, and to the thoroughly international 
character of the accompanying list of workers. In respect to the latter 
feature the Naples station stands alone among marine observatories, 
now numerous, and your Committee are of opinion that the advantages 
associated with the conference of distinguished workers of all nationalities, 
taken in conjunction with the richness of the Neapolitan fauna, present te 
the individual table-holder a combination not to be obtained elsewhere, 
which they regard as sufficient to justify the continued support of the 
British Association.
