The small color mezzotint printed by the painter Jan Ladmiral included with this pamphlet on the arteries and veins of the human intestine was among the earliest applications of full color printing, and the first use of the three-color printing  process in a medical or scientific book. Between 1736 and 1741 Albinus issued six pamphlets, each containing a color mezzotint by Ladmiral, forming the first series of full-color, color-printed anatomical illustrations ever made. The other dissertations included De sede et causa coloris Aethiopum et caeterorum hominum (1737), a treatise on the anatomy and color of human skin; Icon durae matris in coava superficie visae (1738), on the anatomy of the brain; Icon durae matris in convexa superfice visae, ex capite (1738); Icon membranae vasculosae (1738), on the vascular membranes; and Effigies penis humani (1741), on the anatomy of the penis. These six images are  the only color prints produced by Jan Ladmiral, who had learned the process of color printing from the artist Jacob Christoph le Blon, the inventor of the process for printing color mezzotints using the three primary colors.
