“Horner’s syndrome”, due to lesion of the cervical sympathetic. The same syndrome was evoked in animals by Pourfour du Petit in 1727 (see No. 1313). It is a proof that the sympathetic governs the pupillary, vasomotor, sudomotor, and pilomotor functions. It was also described by Claude Bernard, Leçons sur la physiologie et la patbologie du système nerveux, 1858, 2, 473-74, and, less impressively, by E. S. Hare, Lond. med. Gaz., 1838-39, 1, 16-18.
