On the Nature of Mitochondria: Parts I–IV, VIII & IX. Four Offprints, 1922–1925
Philadelphia: The American Journal of Anatomy, 1922. First Separate Editions. Four slim quartos, 203-229; 451-471; 403-419; 131-149 pages, publisher's original stapled wraps. Illustrated with black-and-white plates. A significant group of four original scientific offprints by Ivan E. Wallin documenting his pioneering investigations into the nature and origin of mitochondria, published in the American Journal of Anatomy between 1922 and 1925. The group comprises the first two installments in Wallin’s series, On the Nature of Mitochondria, encompassing Parts I–IV (March and July 1922, pp. 203–229 and 451–471), together with Part VIII, Further Experiments in the Cultivation of Mitochondria (July 1925, pp. 403–419), and Part IX, Demonstration of the Bacterial Nature of Mitochondria (September 1925, pp. 131–149). Wallin was among the earliest scientists to advance a sustained version of what would later become known as the endosymbiotic theory, arguing that mitochondria were bacterial in nature and had originated through a symbiotic relationship between primitive cells and bacteria. Although some of his experimental claims—notably his belief that he had successfully cultured mitochondria independently—were later shown to be mistaken, his broader interpretation anticipated by decades the modern understanding of the bacterial ancestry of mitochondria. Particularly notable is Part IX, in which Wallin states his thesis explicitly in the title, making this group an important primary-source record in the early history of cell biology, evolutionary theory, and the development of endosymbiotic thought. A few markings, some slight discoloration, a few small tears, else in very good condition. Item #538
