The Natural History of Selborne [23]
of animals, sometimes analogous to that of the cryptogamia in the sexual system of plants: and the case is the same as regards some of the fishes: as the eel, etc.
The method in which toads procreate and bring forth seems to me very much in the dark. Some authors say that they are viviparous: and yet Ray classes them among his oviparous animals; and is silent with regard to the manner of their bringing forth. Perhaps they may be ' eso men ootokoi, exo de dzootokoi,(in Greek), as is known to be the case with the viper.
The copulation of frogs (or at least the appearance of it; for Swammerdam proves that the male has no penis intrans) is notorious to everybody: because we see them sticking upon each other's backs for a month together in spring: and yet I never saw, or read, of toads being observed in the same situation. It is strange that the matter with regard to the venom of toads has not yet been settled. That they are not noxious to some animals is plain: for ducks, buzzards, owls, stone curlews, and snakes, eat them, to my knowledge, with impunity. And I well remember the time, but was not eye-witness to the fact (though numbers of persons were), when a quack, at this village, ate a toad to make the country people stare; afterwards he drank oil.
I have been informed also, from undoubted authority, that some ladies (ladies you will say of peculiar taste) took a fancy to a toad, which they nourished summer after summer, for many years, till he grew to a monstrous size, with the maggots which turn to flesh flies. The reptile used to come forth every evening from an hole under the garden-steps; and was taken up, after supper, on the table to be fed. But at last a tame raven, kenning him as he put forth his head, gave him such a severe stroke with his horny beak as put out one eye. After this accident the creature languished for some time and died.
I need not remind a gentleman of your extensive reading of the excellent account there is from Mr. Derham, in Ray's Wisdom of God in the Creation (p. 365), concerning the migration of frogs from their breeding ponds. In this account he at once subverts that foolish opinion of their dropping from the clouds in rain; showing that it is from the grateful coolness and moisture of those showers that they are tempted to set out on their travels, which they defer till those fall. Frogs are as yet in their tadpole state; but in a few weeks, our lanes, paths, fields, will swarm for a few days with myriads of these emigrants, no larger than my little finger nail. Swammerdam gives a most accurate account of the method and situation in which the male impregnates the spawn of the female. How wonderful is the oeconomy of Providence with regard to the limbs of so vile a reptile! While it is aquatic it has a fish-like tail, and no legs: as soon as the legs sprout, the tail drops off as useless, and the animal betakes itself to the land.
Merret, I trust, is widely mistaken when he advances that the rana arborea is an English reptile; it abounds in Germany and Switzerland.
It is to be remembered that the salamandra aquatica of Ray (the water-newt or eft) will frequently bite at the angler's bait, and is often caught on his hook. I used to take it for granted that the salamandra aquatica was hatched, lived, and died in the water. But John Ellis, Esq., F.R.S. (the coralline Ellis), asserts, in a letter to the Royal Society, dated June 5th, 1766, in his account of the mud inguana, an amphibious bides, from South Carolina, that the water- eft, or newt, is only the larva of the land-eft, as tadpoles are of frogs. Lest I should be suspected to misunderstand his meaning, I shall give it in his own words. Speaking of the opercula or covering to the gills of the mud inguana, he proceeds to say that 'The forms of these pennated coverings approach very near to what I have some time ago observed in the larva or aquatic state of our English lacerta, known by the name of eft, or newt; which serve them for coverings to their gills, and
