In tbis way we sball often be led to conclude tbat tbe sympathetic nervous system is at fault when we observe its functions to be disturbed, notwith- standing tbe absence of observed structural change in its chief ganglionic centres. I might say that in some other diseases of the nervous system the same process of reasoning is pursued. In many cases of insanity, for instance, evidence of structural change is wanting; yet who doubts the implication of the brain in the disease? In epilepsy, whose cerebro- spinal origin no one doubts, are there not many cases where visible alteration of structure does not exist ? Let us hope that researches with the aid of the microscope and chemical re-agents will, at no distant day, reveal structural changes in the S3rni- pathetic ganglia to account for the symptoms which we now ascribe to their disordered action. We do not here include those cases of disordered action of the ganglia, which are solely dependent on an eccentric irritant exciting these centres to increased action, and thus inducing sympathetic action in distant parts : in such cases the excitement in a ganglion must as yet be looked upon as dynamical.
