Note on the Spinal portion of some Ascending Degenerations

This is the spinal root on which the classical degeneration experiments of Waller were performed (in Cat). Its sensory division is particularly large, and is, in Macacus as in Man (Swan, Henle), the topmost of the cutaneous spinal, so that its skin-field abuts immediately on that of the cranial Vth. According to the older nomenclature used by Swan, etc. this is the first cervical nerve, what is now called 1st being termed suboccipital. In the Dog Singer and Munzer (Wiener Denkscltr. 57, 1891) figure excellently a degeneration of this root in the posterior column but give little further description.
