Author of: “Zur Kenntniss der Functionen des Rückenmarkes,” Pflüger’s _Archiv._, Vol. XVI.; “Neue Versuche zu einer Lehre von der Schweiss secretion, ein Beitrag zur Physiologic der Nervencentren,” _Ibid._, Vol. XIV., p. 869; “Zur Physiologie der Schweiss secretion,” Virchow’s _Arch._, Vol. LXXVI., p. 529; “Zur Allgemeinen Physiologie der irritabeln Substanzen,” Bonn, 1879; “Ueber gekreutzte Reflexe,” Pflüger’s _Archiv._, Vol. XXII., p. 179, etc., etc. Made experiments in the Physiological Laboratory of Zurich (jointly with Drs. von Borosnyai, Steger, and Pestalozzi) on electrical stimulation of the cerebral cortex. Also experiments on dogs, horses, cats, pigs, oxen, and goats. Cut the nervus ischiadicus to study the action of muscarin and pilocarpin on the excretory glands. Also experiments on cats and kittens with Miss J. A. Kendall. “At the sight of a strange dog, still more so on being bound to the vivisecting table, the cat often breaks out in a violent perspiration on all four feet. It strikes us naturally that the first thing to do is to remove totally all these psychical influences, if it is wished to study thoroughly other causes which may have the effect of stimulating the perspiratory centres. A method frequently employed--narcosis--I have purposely never used; indeed, I _never_ make use of it except for preliminary operations. If the brain is really narcotised, the other nerve centres must also have lost much of their excitability, lesser degrees of narcotisation seem to me to offer very little advantage for the purpose we have in view.”--Pflüger’s _Archiv._, Vol. XIII., p. 375.
