Scientific illustration of desmids (algae)

Single-celled algae, magnified 500 times.

They float in ponds and stream banks. I found them in the Biodiversity Heritage Library, in the Rev. Francis Wolle’s 1884 book Desmids of the United States and list of American pediastrums : with eleven hundred illustrations on fifty-three colored plates .

They look a lot better up close, don’t they?
