The accompanying photo shows de Kleyn, Magnus and Rademaker at the time they were working together on this topic. , “Flexion reflex of the limb, crossed extension-reflex, and reflex stepping and standing”, Journal of Physiol. 40, 28–121, 1910; see p. 112. 32 book ii Fig. 2-4. Magnus, de Kleyn en Rademaker seated at a table in the Physiology laboratory in Utrecht. Rudolf Magnus (1873–1927) became the first professor of pharmacology in the Netherlands in the University of Utrecht in 1908. Before that he worked in Heidelberg, where he had already published a number of original papers on the action of digitalis, the water-balance of the tissues, kidney function and edema, the measurements of pressure in an exposed artery, and the diuretic action of pituarity extracts.

Physiol. 92, 623–643, 1902). At Gottlieb’s Institute of Pharmacology in Heidelberg, he had developed a new technique for studying the automatic rhythm and local reflexes of the intestinal wall. As a student, Magnus had already been deeply impressed by the work of the physiologist W. Kühne (1837–1900), and had attended lectures by the neurologist W. Erb (1840–1921). He had worked under eminent scientists at various laboratories abroad, such as Von Uexküll in Naples as mentioned above (1902), Schäfer (1850–1935) in Edinburgh (1900), Langley (1852–1925) in Cambridge (1905) and Sherrington (1859–1952) in Liverpool in 1908.

The precise nature of the zero condition depends on the nature of the patient’s complaints. For example, if a deaf and dumb subject without labyrinths is immersed in water the body righting reflex will not be operative since there are no optical aids to orientation and as mentioned the labyrinths do not work. Such patients will thus drown if there is no one at hand to help them out of the water. Magnus sketched various such examples in his Cameron Prize lecture delivered at the University of Edinburgh in May 1926.
