Note 169 — Chapter IV · VEGETABLE LIFE IN THE FORESTS OF THE NEW WORLD.
W. H. Davenport (William Henry Davenport) Adams translation
The genus Vibris is the type of a tribe of animalcules commonly known as microscopic eels, remarkable for their extraordinary minuteness. One species is parasitic upon wheat, and when full grown attains a quarter of an inch in length; but the young are so microscopically small that 30,000 might be contained in a single grain of wheat.
