Many of the polypidoms or habitations of the Zoophytes are so minute as only to be accurately discerned under the microscope;—lucky will the investigator of them be if its powers will reveal the Polyp itself;—and there are many methods of preparing them for the purpose;—the Sertulariæ, Plumulariæ, and similar ones may either be mounted in Canada Balsam, or in distilled water, and the Flustra, Membranipora, Lepralia, Catenicella, &c, as opaque objects, gummed down in cells made of dark cardboard, covered with thin glass.
Most earnestly do we recommend our readers not to pass lightly by these many lovely forms of Marine life, such as we have only casually and but faintly depicted here, so sure are we that they will soon exclaim with the Poet—
"————Can such things be,
And overcome us like a Summer's cloud
Without our special wonder?"
