The reactions of the pupil in the chloralosed animal are described, and evidence is put forward which indicates that they may be used as an index of sensation not only from areas supplied by the spinal nerves, but also from those supplied by the autonomic nervous system. Light is thrown on the so‐called sensitisation of the pupil by removal of the superior cervical sympathetic ganglion. The afferent impulses from the heart are shown to pass, at least partly, by way of the spinal cord.
