Bichat revolutionized descriptive anatomy. Where Morgagni and others had conceived of whole organs being diseased, Bichat showed how individual tissues could be separately affected. He covered tissue pathology, system by system in the Anatomie générale, showing that tissues from different organs are similar and subject to the same diseases, and identifying 21 different types of tissues. This was done essentially without a microscope, but marks the beginning of modern histology. The above work and No. 404 are remarkable in their total reliance on verbal description to convey anatomical detail, since neither work contains a single illustration. Translated into English by George Hayward as General anatomy, applied to physiology and medicine. 3 vols., Boston: Richardson and Lord, 1822.
