These glimpses will suffice, perhaps, to give at least a general idea of the manner of thing which the worker at the marine laboratory is seeking to discover when he interrogates the material that the sea has given him. In regard to the publication of the results of work done at the Naples laboratory, the same liberal spirit prevails that actuates the conduct of the institution from first to last. What the investigator dis* covers is regarded as his own intellectual property, and he is absolutely free, so far as the management of this institution is concerned, to choose his own medium in giving it to the world. He may, and often does, prefer to make his announcements in periodicals or books issued in his own country and having no connection whatever with the Naples laboratory. But, on the other hand, his work being sufficiently important, he may, if he so desire, find a publisher in the institution itself, which issues three different series of important publications, under the editorship of Professor Mayer. One of these, entitled _Mittheilungen aus der Zoologische Station zu Neapel_, permits the author to take his choice among four languages--German, English, French, or Italian. It is issued intermittently, as occasion requires. The second set of publications consists of ponderous monographs upon the fauna and flora of the Gulf of Naples. These are beautifully illustrated in color, and sometimes a single volume costs as much as seventeen thousand dollars to issue. Of course only a fraction of that sum is ever recovered through sale of the book. The third publication, called _Zoologischen Jahresbericht_, is a valuable résumé of biological literature of all languages, keeping the worker at the laboratory in touch with the discoveries of investigators elsewhere. The latter end is attained further by the library of the institution, which is supplied with all the periodicals of interest to the biologist and with a fine assortment of technical books. The library-room, aside from its printed contents, is of interest because of its appropriate mural decorations, and because of the bronze portrait busts of the two patron saints of the institution, Von Baer and Darwin, which look down inspiringly upon the reader.
