See Leisure Hours, 3-779, for accounts of small frogs, or toads, said to have been seen to fall from the sky. The writer says that all observers were mistaken: that the frogs or toads must have fallen from trees or other places overhead.
Tremendous number of little toads, one or two months old, that were seen to fall from a great thick cloud that appeared suddenly in a sky that had been cloudless, August, 1804, near Toulouse, France, according to a letter from Prof. Pontus to M. Arago. (Comptes Rendus, 3-54.)
Many instances of frogs that were seen to fall from the sky. (Notes and Queries, 8-6-104); accounts of such falls, signed by witnesses. (Notes and Queries, 8-6-190.)
Scientific American, July 12, 1873:
"A shower of frogs which darkened the air and covered the ground for a long distance is the reported result of a recent rainstorm at Kansas City, Mo."
As to having been there "in the first place":
Little frogs found in London, after a heavy storm, July 30, 1838. (Notes and Queries, 8-7-437);
Little toads found in a desert, after a rainfall (Notes and Queries, 8-8-493).
To start with I do not deny—positively—the conventional explanation of "up and down." I think that there may have been such occurrences. I omit many notes that I have upon indistinguishables. In the London Times, July 4, 1883, there is an account of a shower of twigs and leaves and tiny toads in a storm upon the slopes of the Apennines. These may have been the ejectamenta of a whirlwind. I add, however, that I have notes upon two other falls of tiny toads, in 1883, one in France and one in Tahiti; also of fish in Scotland. But in the phenomenon of the Apennines, the mixture seems to me to be typical of the products of a whirlwind. The other instances seem to me to be typical of—something like migration? Their great numbers and their homogeneity. Over and over in these annals of the damned occurs the datum of segregation. But a whirlwind is thought of as a condition of chaos—quasi-chaos: not final negativeness, of course—
