Curiosities Respecting Animals
Animal Generation-Formation of Animals-Preservation of Animals-Destruction of Animals-Animal Reproductions. See, thro' this air, this ocean, and this earth, All matter quick, and bursting into birth.
Above, how high progressive life may go!
Around, how wide! how deep extend below!
Vast chain of Being! which from God began, Nature s ethereal, human, angel, man, Beast, bird, fish, insect, what no eye can see, No glass can reach; from Infinite to thee, From thee to nothing.
Pope.
In entering upon the subject of Curiosities respecting Animals, we shall first introduce to the reader some interesting observations respecting the generation, formation, preservation, destruction, and reproduction, of animals in general; and, first, of animal generation.
Animal generation holds the first place among all that raise our admiration when we consider the Works of the Creator, and chiefly that appointment by which he has regulated the propagation, which is wisely adapted to the disposition and mode of life of every different species of animals, that people earth, air, or sea. "Increase and multiply," said the benevolent Author of nature, when he pronounced his blessing on the new made world. By virtue of this powerful mandate, all the various tribes of sentient beings have not only been preserved, but increased in an astonishing degree.
It is not in our province to describe the laws of gestation; we will content ourselves with a few brief hints upon this subject; and we shall find, that in different animals, nature operates in different ways, in order to produce the same general end.
The human female, and the female of quadrupeds, are possessed of a temperate cherishing warmth; this fits them for easy gestation, and enables them to afford proper nourishment to their young, till the time of birth.
Birds are intended to soar in the air, or to flit from place to place in search of food. Gestation, therefore, would be burdensome to them. For this reason, they lay eggs, covered with a hard shell: these, by natural instinct, they sit upon, and cherish till the young be excluded. The ostrich and the cassowary are said to be exempt from this law; as they commit their eggs to the sand, where the intense heat of the sun hatches them.
Fishes inhabit the waters, and most of them have cold blood, unfit for nourishing their young. The all-wise Creator, therefore, has ordained that most of them should lay their eggs near the shore; where, by means of the solar rays, the water is warmer, and also fitter for that purpose; and also because water insects abound more there, which afford nourishment to the young fry.
Salmon, when they are about to deposit their eggs, are led by instinct to ascend the stream, where purity and freshness are to be found in the waters: and to procure such a situation for its young, this fish will endure incredible toil and hazard.
The butterfly-fish is an exception to this general law, for that brings forth its young alive. The species of fish whose residence is in the middle of the ocean, are also exempt. Providence has given to these, eggs that swim; so that they are hatched among the sea-weeds, which also swim on the surface. The various kinds of whales have warm blood, and therefore bring forth their young alive, and suckle them with their teats.
Some amphibious animals also bring forth their young alive, as the viper, &c. But such species as lay eggs, deposit them in places where the heat of the sun supplies the want of warmth in the parent. Thus the frog, and the lizard, drop their's in shallow waters, which soon receive a genial heat by the rays of the sun; the common snake, in dunghills, or other warm
