"Les Grands Processus Morbides" by Jean Joseph Picot. This nineteenth-century treatise on inflammation surveys exudation, pus formation, and tissue regeneration, and engages in the debate over etiology and origin theories. It distinguishes two main classes of exudates—coagulable fibrinous exudates that can form false membranes and may accompany serous, mucous, pleural, peritoneal, and pulmonary inflammations, and non-coagulable exudates that are largely serous or purulent and often absorbed during healing. It describes pus as serum plus leukocytes, its variable characteristics, and its potential to yield granulations and microzymas in putrefaction, along with reactions to pyic acids and necrotic debris. The discussion moves to granulation tissue (blastema), embryoplastic nuclei, neovascularization, and the developmental paths of healing by regeneration or by granulation that may progress to pus or scarring. It surveys competing leukocyte origins (cell-centric, diapedesis, endogenous leukocyte generation) and the tendency to emphasize generation within the inflammatory milieu. The author treats inflammation as a process that destroys or hypertrophies tissue, outlines external and internal causes, critiques the concept of “irritation,” and details tissue changes, the spectrum of resolution, suppuration, and gangrene, and practical diagnostic implications. Overall, it frames general pathology as a biology-based enterprise with the blood and circulation as the central milieu.
