Paper, 'The innervation of the renal blood-vessels' by John Rose Bradford Bradford writes: 'The following work was undertaken in order to map out the origin, course, and nature of the renal nerves more accurately than had hitherto been attempted. It was considered (more especially in the light of Gaskell’s well-known work on the sympathetic) important to decide whether the renal and other abdominal vascular nerves were of two kinds, i. e., vaso-constrictor and vaso-dilator, or whether the latter nerves could not be demonstrated to exist. This research was carried out exclusively on the dog, inasmuch as this was the animal used by Gaskell in his work.' Annotations in pencil and ink. Subject: Physiology Received 1 February 1889.
