"So safe in waves prolific Volvox dwells, And five descendants crowd his lucid cells; So the male Polypus parental swims, And branching infants bristle all his limbs; So the lone Taenia, as he grows, prolongs His flatten'd form with young adherent throngs; Unknown to sex the pregnant oyster swells, And coral-insects build their radiate shells; 90 Parturient Sires caress their infant train, And heaven-born STORGE weaves the social chain; Successive births her tender cares combine, And soft affections live along the line. [Footnote: _Prolific Volvox_, l. 83. The volvox globator dwells in the lakes of Europe, is transparent, and bears within it children and grandchildren to the fifth generation; Syst. Nat.] [Footnote: _The male polypus_, l. 85. The Hydra viridis and fusca of Linneus dwell in our ditches and rivers under aquatic plants; these animals have been shown by ingenious observers to revive after having been dried, to be restored when mutilated, to be multiplied by dividing them, and propagated from portions of them, parts of different ones to unite, to be turned inside outwards and yet live, and to be propagated by seeds, to produce bulbs, and vegetate by branches. Syst. Nat.] [Footnote: _The lone Taenia_, l. 87. The tape-worm dwells in the intestines of animals, and grows old at one extremity, producing an infinite series of young ones at the other; the separate joints have been called Gourd-worms, each of which possesses a mouth of its own, and organs of digestion. Syst. Nat.] [Footnote: _The pregnant oyster_, l. 89. Ostrea edulis dwells in the European oceans, frequent at the tables of the luxurious, a living repast! New-born oysters swim swiftly by an undulating movement of fins thrust out a little way from their shells. Syst. Nat. But they do not afterwards change their place during their whole lives, and are capable of no other movement but that of opening the shell a little way: whence Professor Beckman observes, that their offspring is probably produced without maternal organs; and that those, who speak of male and female oysters, must be mistaken: Phil. Magaz. March 1800. It is also observed by H. I. le Beck, that on nice inspection of the Pearl oysters in the gulf of Manar, he could observe no distinction of sexes. Nicholson's Journal. April 1800.]
