Science and experience have thus far revealed no other way of making tolerable the agonizing pain which Mr. Edgerton now endures. This pain is quite inconceivable by the ordinary mind. It can not be described, and the only hint by which an outsider can be let into something like an inkling of it is the supposition (which I have elsewhere used) that pain has become _fluidized_, and is throbbing through the arteries like a column of quicksilver undergoing rhythmical movement. If the arteries were rigid glass tubes, and the pain quicksilver indeed, there could not be a more striking impression of ebb and flow every second against some stout elastic diaphragm whose percussion seems the pain which is felt. This is especially the case along the course of the sciatic nerve and all its branches, where the pulse of pain is so agonizing that the sufferer can not keep his legs still for an instant. There is occasionally severe pain of this kind in the arms also, but this is very rare. The suffering which usually accompanies that of the legs is a maddening frontal headache, and a dull perpetual ache through the region of the kidneys, described as a sensation of "breaking in two at the waist;" nausea, burning, and constriction about the epigastrium, and intense sensitiveness of the liver--besides general nervous and mental distress which has neither representative nor parallel. All these symptoms are instantaneously met and for the time being counteracted by the hot-bath. When the patient gets tired of it, and it temporarily loses its efficiency from this cause, great advantage may be gained by substituting either the Russian bath or the common box vapor-bath, with an aperture in the top to stick the head out of, and a close-fitting collar of soft rubber to prevent the escape of the steam.
