All four offprints housed in a brown cloth backed custom folder with ex-libris of H F. Norman M D on inner cover. ---- Norman 1668, 1669, 1670, 1672 (these copies). FIRST EDITION, offprint issues. Rudolf Magnus (1873-1927) was a German physiologist who is best known for his studies of physiology of posture (see Garrison-M. 661 and 663.1). Pavlov received the 1904 Nobel Prize in physiology / medicine for his studies of the physiology of digestion, which revealed the part that the nervous system plays in controlling digestive secretions. Most of Pavlov's later scientific career was devoted to the physiology of the brain and of higher nervous activity. "In conducting his researches, Pavlov introduced the method of long-term or continuous experimentation, which - in contrast with traditional vivisectional methods - allowed him to study the operation of physiological processes in healthy animals under normal conditions over extended periods of time. His investigations of the nervous system's role in digestion led him to explore the phenomenon of "psychic" stimulation; i.e., salivary secretion prompted by the sight or smell of food rather than by direct contact. In Pavlov's hands this became a powerful tool for investigating the functions of the cerebral cortex and the physiology of behavior. The most famous outcome of his researches is, of course, the artificial conditioned reflex, in which physiological processes such as salivation are arbitrarily associated with stimuli such as the ringing of a bell."
