You request me confidentially, to examine the question, whether the Supreme Court has advanced beyond its constitutional limits, and trespassed on those of the State authorities? I do not undertake it, my dear Sir, because I am unable. Age and the wane of mind consequent on it, have disqualified me from investigations so severe, and researches so laborious. And it is the less necessary in this case, as having been already done by others with a logic and learning to which I could add nothing. On the decision of the case of Cohens vs. The State of Virginia, in the Supreme Court of the United States, in March, 1821, Judge Roane, under the signature of Algernon Sidney, wrote for the Enquirer a series of papers on the law of that case. I considered these papers maturely as they came out, and confess that they appeared to me to pulverize every word which had been delivered by Judge Marshall, of the extra-judicial part of his opinion; and all was extra-judicial, except the decision that the act of Congress had not purported to give to the corporation of Washington the authority claimed by their lottery law, of controlling the laws of the States within the States themselves. But unable to claim that case, he could not let it go entirely, but went on gratuitously to prove, that notwithstanding the eleventh amendment of the constitution, a State _could_ be brought as a defendant, to the bar of his court; and again, that Congress might authorize a corporation of its territory to exercise legislation within a State, and paramount to the laws of that State. I cite the sum and result only of his doctrines, according to the impression made on my mind at the time, and still remaining. If not strictly accurate in circumstance, it is so in substance. This doctrine was so completely refuted by Roane, that if he can be answered, I surrender human reason as a vain and useless faculty, given to bewilder, and not to guide us. And I mention this particular case as one only of several, because it gave occasion to that thorough examination of the constitutional limits between the General and State jurisdictions, which you have asked for. There were two other writers in the same paper, under the signatures of Fletcher of Saltoun, and Somers, who, in a few essays, presented some very luminous and striking views of the question. And there was a particular paper which recapitulated all the cases in which it was thought the federal court had usurped on the State jurisdictions. These essays will be found in the Enquirers of 1821, from May the 10th to July the 13th. It is not in my present power to send them to you, but if Ritchie can furnish them, I will procure and forward them. If they had been read in the other States, as they were here, I think they would have left, there as here, no dissentients from their doctrine. The subject was taken up by our legislature of 1821-'22, and two draughts of remonstrances were prepared and discussed. As well as I remember, there
