Cast

Try as we might, we cannot autopsy (from Greek, to see for oneself) the whole natural world. As diversity of life reduces, we further lose the ability to be amphibious (from Greek, to lead dual lives), to be above a surface and below, not to mention "achieving focus" in a single plane. Texts include A Treatise on Optics (1845) by David Brewster; Atlas of Nerve Cells (1896) by Moses Allen Starr; and The Microscope (1899) by Simon Henry Gage.
