At the time I recd your letter of the 7th July, I was engaged in completing some business which would not admit of delay, & as I wished to examine with attention, & a reference to books, the decisions you had given, I determined to postpone my answer until this could be done. In the mean time, our domestic misfortunes occurred, which compelled me to take my family to the mountains, where I remained until it was necessary to commence my circuit duty.

I have not yet completed my Circuit & shall defer to a future time a statement of the decisions which have been already made— My present object in writing is to ascertain what has been the practice, if any, in the District or circuit Courts of Pennsylvania & New Jersey upon Summary applications to repeal patents under the 10th Sect. of the Patent act 1793. A case is now before me from the District Court upon a writ of error from its decisions under that Section— Several questions have arisen. 1.

I had a short session at Phila, and decided but few Cases, but most of these are interesting. Without further preface, I proceed to give you an abbreviated report of them.

I was about to sit down to give you an account of my autumnal Circuit, when I had the pleasure of receiving your late letter— Before I say one word on this subject, I beg to apologize for not acknowleging before the barrel of hams which you sent me— The barrel of hams safely arrived at Boston, & there by the carelessness of the Captain or Consignee or both, it was left on the wharf for a day or two, & thus all were stolen except five— These I received & they were so good that I regretted extremely my loss—& a

I had the pleasure of receiving your late letter yesterday. The question which you state is indeed an important & delicate one. I have never yet had reason to decide it although it has been twice within my view.

I have not yet heard whether your session in Philadelphia is over & you have returned to Mount Vernon. I had supposed from your last letter that your tour would be a short one; but not having heard of its being over, I doubt whether you may not be still engaged in Philadelphia.

I am grieved to learn by your late letter of your continued indisposition— I heard in the autumn quite by accident of your sickness at Philadelphia; but I presumed it was temporary. I most earnestly hope & pray that a good Providence will restore you to health & enable you to attend at the February Term. I shall feel quite lost <illegible> without you; & must say in all sincerity & frankness that I know not in whose judgment I have implicit a reliance, as in yours.

I thank you for your late letter containing the Decisions of your spring & autumnal Circt.¹ I shall confine my Answer to your own Cases, intending to bring you an abstract of mine when I come to Washington this winter. Until very lately I thought it would be unnecessary, as the 4th volume of Mason is partly through the press, & I supposed it would include them. I think now it will not— But I shall bring you the printed sheets, as far as they go, which will be about 400 pages.
