For the analysis of the symptoms of nervous disease in terms of normal function, the fundamental importance of the experimental physiology of the nervous system can scarcely be overestimated. Unfortunately, the demands of clinical neurology rarely allow us the opportunity of studying at first hand the experimental side of neurology. Moreover, although the fruits
