Cellular Pathology: as Based Upon Physiological and Pathological Histology. Twenty Lectures Delivered in the Pathological Institute of Berlin During the Months of February, March and April, 1858

Cellular Pathology: As Based Upon Physiological And Pathological Histology. Twenty Lectures Delivered In The Pathological Institute Of Berlin During The Months Of February, March And April, 1858 by Rudolf Ludwig Karl Virchow. This concise volume presents Virchow's cellular paradigm, delivered as lectures at the University of Berlin in early 1858, arguing that life and disease are rooted in cells—the fundamental units of both physiology and pathology. The text traces the primacy of the cell across plant and animal life, rejects spontaneous generation, and emphasizes an organized intercellular matrix and cell territories that govern nutrition and tissue behavior. It surveys epithelial, connective, and higher tissues, the role of the nucleus, cytoplasm, and cell membranes, and outlines how glands originate from epithelial proliferation. The lectures discuss nutrition through vascular and cellular networks, and introduce concepts such as vascular territories, endogenous cell formation, histological substitutions, and the social metaphor of the organism as a community of cells. The work blends historical debate with experimental illustration, using numerous preparations and wood engravings to advance a unified, cell-centered view of life and disease.
