The upper floors of the zoölogical station are seldom shown to visitors, but these are almost more interesting than the tank room below. Here the great scholars who make a life study of these strange inhabitants of the deep have their tables; here the dredgings of the sea are brought by fishermen and divers for them to assort; here sea animals are developed by them from the egg, and even from invisible germs. Each investigator into the strange lower world is furnished with his own aquaria, suited to the special branch he may be studying, for nearly all are interested in a special branch of zoölogy. One man has come a long distance to pursue the study of sponges, and he is furnished with a perfect garden of them, for they are brought up from this part of the Mediterranean in infinite variety. Another student is studying the habits of mollusks, and basins and jars of these and their eggs are near him. There are divers' costumes hanging on the walls in which the _savants_ may themselves descend to the bottom of the sea and study the inhabitants in their native houses. There are laboratories and libraries here, adapted to the most exhaustive study, and a fleet of small boats is also kept exclusively for the use of the zoölogical station. Fishermen constantly bring in baskets filled with what seems to be only wet rubbish, heaps of stones, and worthless bits of pulp. This is examined and assorted by trained eyes, and placed in tanks of water where siphons are constantly pouring fresh sea water, after which the rubbish is quietly left until accustomed to its new quarters. Then cautiously this rubbish begins to move, the stones stir, and the pulp opens into the beautiful colors, the plants, the gauzy scarfs, and the numerous other strange things afterward shown to the public in the aquarium below. Along the walls of these upper rooms are jars wherein are preserved many curious denizens of the sea that have been killed by powerful chemicals, which have surprised the delicate animals before their sensitive tentacles have had time to close, thus preserving to science many rare creatures impossible to keep long in captivity. The great cost of this establishment is maintained in several ways--by the issuing of publications and scientific papers in several languages, by the rents from the desks or tables used by the investigators, and by the unusually large price of admission demanded from the public at the aquarium entrance. In addition to this are the fees from the students who come from afar to study here. A payment of four hundred dollars each gives students the right to study in the Naples zoölogical station for ten months of the year. SCIENCE IN EDUCATION.[40] BY SIR ARCHIBALD GEIKIE, D. C. L., F.
