Marvels of pond-life; or, A year's microscopic recreations among the polyps, infusoria, rotifers, water-bears and polyzoa
A popular microscopy handbook by Henry J. Slack, published in London by Groombridge in 1871 for amateur naturalists working through a year of pond collecting. The figures are numbered outline drawings of rotifers, infusoria, polyps and water-bears, each specimen isolated on blank paper with fine hatched stippling for internal organs and radiating hair-thin lines for cilia and tentacles \u2014 usable as line silhouettes, pattern fills, or diagrammatic spot art.
