LEGALLOIS, Julien Jean Csar (1770-1814). Expriences sur le principe de la vie, notamment sur celui des mouvemens du coeur, et sur le sige de ce principe; suivies du rapport fait la premire classe de l'Institut sur celles relatives aux mouvemens du coeur. Paris: d'Hautel, 1812.
8o (214 x 140 mm). (Minor spotting to some text.) Folding engraved plate. Original blue wrappers, uncut, some leaves unopened (rebacked, retaining original paper spine label, slightly soiled); modern cloth case.
FIRST EDITION. Legallois discovered the site of the respiratory center in a circumscribed area of the medulla oblongata, a discovery that replaced the belief that respiration depended on the entire brain. He also described the action of the vagus nerve on respiration, showed that bilateral section of the vagus can produce fatal broncho-pneumonia, and revived the neurogenic theory of the heart's action (that the motor power of the heart comes from the spinal cord via the branches of the sympathetic nervous system). Cushing L31; Garrison-Morton 928; Waller 5679; Wellcome III, p.479; Norman 1324.
