“The Journal of Anat. and Physiol. for May, 1869, contains a short communication by Prof. Rutherford relating to the action of the section of the vagus on the blood pressure. According to Rutherford’s experiments the results of section of the vagus depend upon the condition of the alimentary canal; when the canal is full, the section of the nerves occasions heightened pressure, whereas in starving animals this operation causes no alteration in the blood pressure. Rutherford thinks this phenomenon is caused by the depressory distention of the intestinal vessels by the food contained in them. He supposes that the sensory nerves ending in the vagus root are stimulated by the food. The division of these ducts occasions a reflex narrowing of the vessels and hence heightened pressure. This important hypothesis of Rutherford’s (neither the amount nor the duration of blood pressure has been given, nor the time of feeding, etc.), has, as far as we know, not been tested experimentally, although the fact is often brought forward. This was the chief incentive which prompted me to make the following experiments:—All the experiments (twenty in all) were made exclusively on dogs, the directions given by Rutherford being carefully followed. The animals were immediately placed under the effects of curare.… The nervus vagi were cut through one after the other … other sensory nerves (mostly the Nervus dorsalis pedis) were cut.… The results of the experiments made by me in this manner were, excepting in two cases, diametrically opposed to the results described by Rutherford.”—Zur Lehre ueber die Innervation der Blutbahn, Pflüger’s Archiv., Vol. XX., p. 210.

Made experiments in the Pharm. Lab., Strasburg, also at Physiol. Lab., Turin, on the exposed bladders of dogs. The bladders were sometimes “left in the abdominal cavity.”—Arch. Ital., Vol. II., p. 303. Also experimented on the effects of curare and strychnine.
