danger of the first injury was _now_ only to be estimated by its threatening consequences at the stage of progress of the case when it arrived at the Mountain. All too plainly marked by fearful features the true character of the effects of the assault in the Senate, and plainly showed their fatal tendencies in the condition of the man. At this stage of the case, whatever might have been or might now be the condition of the suffering internal organs, debility and exhaustion of life was manifestly the clearest phenomenon visible. “‘This was accompanied with an interrupted action of the muscles of voluntary motion, great weakness of the loins, inability to protract beyond a few minutes any mental effort without pain, weight and uneasiness in the head, together with soreness in the region of the cervical vertebræ; all of which symptoms, taken together, demonstrate a case ravaged by severe disease in the great nervous centre, and showing in that region still a highly pathological condition of parts. All the symptoms being of a depressed order, exhaustion and weakness predominating in all the functions, the clear indication in the case was to reënergize the man in every way and by every influence. This, it seemed, would be most effectually secured by a judicious diet, mild tonic agents, constant exercise in the open air on horseback or in a carriage, and by cessation of all active efforts of the diseased parts, and a gradual stringing up and intonation of the whole body under the influence of mountain air, mountain water, and change of climate. Within five weeks, the effects of this treatment were marked and clearly visible to all. So emphatic were they in the consciousness of Mr. Sumner, that he could not be persuaded he was still an invalid, and not almost well and ready for the field of active operations. He left the Mountain prematurely, before he was hardened and his body restored to its normal tone. This was done contrary to my urgent advice and entreaties. It was clearly apparent, that, with one more month of the bracing influences of the Mountain, he would have been much better than at present, and the perfect final restoration of the Senator’s health greatly facilitated. “‘Yours truly, “‘R.
