ANNIVERSARY ADDRESS. 9 
for dredging, and the equipment included diving apparatus, 
arrayed in which Dr. Dohrn sometimes takes a walk at the 
bottom of the sea for the mere pleasure of it. There are forty 
tables available for work, but only fifteen were at that time 
occupied. Each table is charged £80 per annum. The German 
Government pays for ten, Cambridge one, and the British Associa- 
tion one. Each table has glass tanks with streams of sea-water 
running through them, besides other appliances. Three publica- 
tions are carried on to report the work of the station, all published 
at Leipsic. One of them is beautifully illustrated. 
The aquarium on the ground floor is admirably contrived, and 
is filled with most interesting and beautiful objects. A living 
torpedo is usually kept in a convenient place for giving shocks to 
visitors. I was told that the annual expense of said whole 
establishment amounts to about £5,000. 
Dr. Dohrn has attained to great success in preserving specimens 
of the most delicate forms of animal life without change of colour. 
Different species require different treatment. Some are killed 
by immersion in strong corrosive sublimate before transference to 
alcohol ; and it was discovered accidentally that the use of tobacco 
smoke in stupefying some jelly-fish was successful in preserving 
delicate colours that had always hitherto proved evanescent. Dr. 
Dohrn sent a large collection to the late Fisheries Exhibition, 
and the specimens (nearly 400 in number) were much admired 
for the extraordinary success attending their preservation. 
You may remember that in my address to the Society three 
years ago I called your attention to this Zoological Station at 
Naples, and to the efforts then being made by Baron Maclay to 
establish such a station here, and I asked you for contributions to 
assist in this enterprise. The Council, on behalf of the Society, 
made such a donation to the funds as to entitle it to nominate a 
worker in the laboratory, but no one applied for this privilege. 
I call your attention to the matter again, in the hope that some 
member of the Society may be disposed to take up biological investi- 
gations, and make use of the convenient laboratory now available.
