Your favor of the 25th inst., recd today, induces me to do immediately what I had mentally arranged to do after my return from Trenton—answer your interesting letter of the 4th July. But first allow me to excuse myself from the censure to which I am apparently obnoxious for having postponed the performance of this duty to this late day. I took that letter out of the office in Alexa.

Your three letters of the 25th Jany, 6 & 22d february have been recd, but not duly, the first written having been detained at the Alexandria post office until three days ago, when it was forwarded to me. As to the one containing observations upon the case of Conn. vs. Penn., I must postpone an answer until I can look again over my notes, which I left at Mount Vernon, as also the opinion in extenso.

Last Monday was the commencement of my stated February session. It was also the day to which the Circuit Court stood ajourned. All the Lawyers concerned in the Penn. causes were engaged in the State Courts. I sent Mr Caldwell to inquire if they had anything to do in the Circuit Court; & particularly in the Case of Conn. & Penn.
