In "The Crime against Kansas" there are two or three sentences which Sumner afterwards expunged, and this shows that he regretted having said them; but it is the greatest of his orations, and Webster's reply to Hayne is the only Congressional address with which it can be compared. One is in fact the sequence of the other; Webster's is the flower, and Sumner's the fruit; the former directed against the active principle of sedition, and the latter against its consequences; and both were directed against South Carolina, where the war originated. Sumner's speech has not the finely sculptured character of Webster's, but its architectural structure is grand and impressive. His Baconian division of the various excuses that were made for the Kansas outrages into "the apology _tyrannical_, the apology _imbecile_, the apology _absurd_, and the apology _infamous_," was original and pertinent. Preston S. Brooks only lived about six months after his assault on Sumner, and some of the abolitionists thought he died of a guilty conscience. Both in feature and expression he bore a decided likeness to J. Wilkes Booth, the assassin of President Lincoln. It might have proved the death of Sumner, but for the devotion of his Boston physician, Dr. Marshall S. Perry, who went to him without waiting to be telegraphed for. It was also fortunate for him that his brother George, a very intelligent man, happened to be in America instead of Europe, where he lived the greater part of his life. The assault on Sumner strengthened the Republican party, and secured his re-election to the Senate; but it produced nervous irritation of the brain and spinal cord, a disorder which can only be cured under favorable conditions, and even then is likely to return if the patient is exposed to a severe mental strain. Sumner's cure by Dr. Brown-Sequard was considered a remarkable one, and has a place in the history of medicine. The effect of bromide and ergot was then unknown, and the doctor made such good use of his cauterizing- iron that on one occasion, at least, Sumner declared that he could not endure it any longer. Neither could he tell positively whether it was this treatment or the baths which he afterwards took at Aix-les-Bains that finally cured him. His own calm temperament and firmness of mind may have contributed to this as much as Dr. Brown-Sequard. When Sumner returned to Boston, early in 1860, all his friends went to Dr. S. G. Howe to know if he was really cured, and Howe said: "He is a well man, but he will never be able to make another two hours' speech." Yet Sumner trained himself and tested his strength so carefully that in the following spring he delivered his oration on the barbarism of slavery, more than an hour in length, before the Senate; and in 1863 he made a speech three hours in length, a herculean effort that has never been equalled, except by Hamilton's address before the Constitutional Convention of 1787.
