OUR FRESH-WATER POLYZOA.
BY THE REV. W. HOUGHTON, M.A., F.L.S.
F all the beautiful forms of animal life that tenant the waters of our rivers and ponds in marvellous profusion, there are none, I think, that excel, and few that equal in elegance and interest, the Polyzoa. It is invidious, perhaps, to draw comparisons in nature, where all is perfect; the naturalist will see as much to admire in the common earthworm as in the rarest and most prized zoological treasure, not that in external form the humble worm recommends itself as an object of attraction, but because its structure, like that of every created thing, is so admirably adapted to the wants and habits of the animal. Be this, however, as it may, there is no doubt that beauty of external form, although it may be the only point for which the uninitiated care, is an additional charm in the eyes of the zoologist. Who does not remember the thrill of pleasure that ran through him when first he beheld, through the magic crystals of the microscope, a group of Vorticelle with their delicate spiral stems and ciliated glassy bells? or who that has ever watched the beaded Melicerta mould its tiny round bricks, and then bend itself down and add pellet after pellet to its tube, will say he has not experienced a more than ordinary treat, and a kind of gratification which it is impossible to describe?
This is the month of April, and it is too early to attempt to find specimens of any of the species of Polyzoa, with the exception of Fredericella Sultana, of which more anon. Still, take your collecting bottles and pocket lens, and come along with me: I shall be able, I know, to teach you a useful lesson in the art of discovering Fresh-water Polyzoa; for you must know that it is quite possible you may be living close to a pond in which live hundreds of one of the most prized species, and yet be quite unable to find a single specimen. We will go to this large reservoir, which supplies the canal; here the water is beautifully clear, and in the summer time the willows and alders on the margins of the bank form a pleasant shade, and ever and anon let fall their dead branches into the water, a
