At a very early period of the history of the glycogenic function of theLiver, it was found that the formation of sugar could be influenced throughthe nervous system. Bernard, for instance, observed that when the floor ofthe fourth ventricle, between the origin of the Pneumogastric and Auditorynerves (see Fig. 180) was pricked with a needle,* so great an increase inthe quantity of sugar generated was effected in the course of an hour that was discharged by the urine, a con-dition of diabetes, lasting at most fortwenty-four hours, being , however, the same point be prickedafter the branches of the sympathetic tothe liver, which chiefly proceed fromthe splanchnics, have been divided, or theliver be removed entirely, no Nor does any diabetes followpricking the floor of the fourth ven-tricle in winter frogs, or in animals keptlong fasting, or which have been sup-plied with arsenious acid in their food,in all o
