"Much curiosity and some comment have been exerted by the marvellous identities in a plan of Government proposed by Charles Pinckney in the Convention of 1787 as published in the Journals with the text of the Constitution, as finally agreed to. I find among my pamphlets a copy of a small one entitled Observations on the Plan of Government submitted to the Federal Convention, in Philadelphia, on the 28th of May, by Mr. C. Pinckney, a Delegate from S. Carolina, delivered at different times in the Convention. "The copy is so defaced and mutilated that it is impossible to make out enough of the plan, as referred to in the Observations, for a due comparison of it with that printed in the Journal. The pamphlet was printed in N. York by Francis Childs. The year is defaced. It must have been not very long after the close of the Convention, and with the sanction, at least, of Mr. Pinckney himself. It has occurred to me that a copy may be attainable at the printing office, if still kept up, or in some of the libraries or historical collections in the city. When you can snatch a moment, in your walks with other views, for a call at such places, you will promote an object of some little interest as well as delicacy, by ascertaining whether the article in question can be met with. I have among my manuscript papers lights on the subject. The pamphlet of Mr. P. could not fail to add to them. "April, 1831." At some time subsequent to the 6th of April he wrote to Mr. Paulding, saying that in a previous letter "I requested you to make an inquiry concerning a small pamphlet of Charles Pinckney printed at the close of the Federal Convention of 1787;" and on the 6th of June he again wrote to Mr. Paulding, "June 6th, 1831. "DEAR SIR.--Since my letter answering yours of April 6th, in which I requested you to make an inquiry concerning a small pamphlet of Charles Pinckney printed at the close of the Federal Convention of 1787, it has occurred to me that the pamphlet might not have been put in circulation, but only presented to his friends, etc. In that way I may have become possessed of the copy to which I referred as in a damaged state. On this supposition the only chance of success must be among the books, etc., of individuals on the list of Mr. Pinckney's political associates and friends. Of those who belonged to N. York, I recollect no one so likely to have received a copy as Rufus King. If that was the case, it may remain with his representative, and I would suggest an informal resort to that quarter, with a hope that you will pardon this further tax on your kindness."
