    happening altogether apart from malarial influences, hut usually seen in cachectic subjects. In such cases the dilating wave occurs as a condition of used-up nerve-force, the vessel equilibrium maintained up to the time of commencement of pain having exhausted the supply of nerve-energy necessary to support it. Vessel-relaxation follows where the mobility of a gan- glionic centre is greatest, with the consequent disten- sion and stretching of sentient tissues indicated. All of which conditions cease when sufficient force has again collected to enable the inhibitory centre to re- assert its control over the vessels in the disturbed area. With this re-establishment of the normal calibre of the arterioles, the pain intermits.0 Here it is necessary to insist on the essential part played by the (jamjlia in this role of events, they being the co-ordinating media determining, by the relation- ships of their afferent and efferent fibrillae, the exact region which shall exhibit the reflected tissue metamor- phoses. But they have another and wider action, due likewise to the anatomical communication of nerves which join them from distant regions, and which thus bring internal organs, especially the intestinal mucous tract, within the sphere of then- influence. In this way there is established very intimate relationships between, e.g., the skin, and visceral mucous membranes, so that * The practical result of this aspect of the association of herpes and neuralgia was the suggestion by the Author of the use of ergot for the relief of the pain accompanying shingles, in a paper read at the meeting of the British Medical Association at Oxford, August, 1868, and published in the Brit.
