“Since Mr. Sumner’s return to Boston, he has been gradually improving. He has followed a rigid system of exercise in the open air, and carefully avoided all intellectual excitement. The pressure in his head, or sensation of weight, which formerly came on after the slightest mental or physical exertion, and which was very oppressive, is now felt only after great fatigue, or considerable effort of the mind. He still complains, after sitting up for a long time, of pain in his back; and when he rises from his bed or chair, he finds at first some difficulty in using the muscles of the lower extremities, but after walking a short time they become quite flexible and under the complete control of the will. His appetite is good, he sleeps much better than he did, and is gaining flesh and strength. I see no reason why he may not entirely recover, unless he allows himself too soon to enter upon his Senatorial duties. He has already assumed the external appearance of health. Time and mental repose will do the rest. “I think it is impossible to decide with absolute certainty what the pathological condition of Mr. Sumner’s brain has been; but I am inclined to the opinion of Dr. Jackson, ‘that the brain, as well as the spinal cord, has been the seat of some serious lesion.’ The long continued sense of weight in his head, the pain along the spine, the partial loss of power in the lower extremities, the loss of flesh during the first three months after the attack, and the wakefulness, without any affection of the mind, would lead, I think, to this conclusion. Had the patient died, a _post-mortem_ examination would have determined conclusively the character of the injury; but we can only make an approximation to a true appreciation of the case by a cautious interpretation of the symptoms.” * * * * * This diagnosis does not extend beyond December, 1856. Subsequent newspapers contain notices of the case. The diagnosis, at a later day, by Dr. Brown-Séquard, has never been published. “WHATEVER MASSACHUSETTS CAN GIVE, LET IT ALL GO TO SUFFERING KANSAS.” TELEGRAPHIC DESPATCH TO BOSTON, JUNE 6, 1856. On the 3d of June, 1856, a resolution for the relief of Kansas failed in the Massachusetts Legislature, mainly, it was alleged, through the hostility of Governor Gardner. On the next day a message from the Governor was received by the Legislature, recommending the payment of the expense of the illness of Mr. Sumner. This was followed in the Senate by a resolution to the same effect. On learning these proceedings, Mr. Sumner dictated the following telegraphic despatch, which was signed by his immediate representative in Congress. WASHINGTON, June 6, 1856.
