FIRST EDITION; four memoirs on the dynamics of the circulatory system. “Through a chance discovery in 1771… Spallanzani first established the existence of arteriovenous anastomoses in a warm-blooded animal. He also studied the effects of growth (in the chick embryo and tadpole) upon circulatory mechanisms; the influence of gravity and the consequences of wounds on different parts of the vascular system; and changes in the languid or failing circulation in dying animals. Finally, Spallanzani demonstrated that the arterial pulse is due not to mere cardiac displacements but to lateral pressure upon an expansile wall from cardiac impulsions conveyed by the blood column. A total of 337 experiments were outlined and expounded in four dissertations…” (DSB). Prandi, Bibliografia, pp. 35–36. Willius & Dry, p. 89.
