From Jan Ingenhousz (unpublished)
Paris 9th of August 1788
My dear friend

I received some time ago your kind lettre dated Philadelphia Febr. 11. 1788 which gave me the greatest satisfaction because it was an authentic proove of your being still an inhabitant of this world, which was become very problematic. I was at that time preparing for a literary excursion to Paris and London, in which places I intended to publish some new works, which are now under the Press here. I arrived here some days ago and saw yesterday Mr. Jefferson for the first time; and as he told me he should send a paquet to Philadelphia to morrow by a lady, who set out for America, I proposed him to make up immediately the power of atorney according to the model sent to me by Mr. Vaughan. He did it very willingly and was in every respect very civil and oblidging to me. Which power of atorney I inclose in the paquet. It will empower him to act in my name in the affaire with Mr. Wharton; tho I should not like to spend much money with little or no hope to recover what is due to me. I wanted two things. Viz. the account of what is still du to me of the sale of the marchandises belonging, for one third part, to me and, of the parcel which Mr. Vaughan wrote me was found still in Mr. Wharton’s warehous marked as a parcel belonging to me and not yet sold. I wanted allso the copy of all the letters of Mr. Wharton accompanying the remittances which he sent to Mr. Coffyn, and which letters slong can proove, whether Mr. Coffyn wrong’d me by keeping my money, or whether there had been made a private agreement between Mr. Wharton and Coffyn, by virtu of which Mr. Coffyn kept allmost the whole amount of the remittances to himself. Mr. Vaughan, if fancy had forgot to inclose in his last lettre the account of my affairs with the Whartons, as you informed me that account was now made up.

Your advise and that of Mr. Vaughan to wait with the Congress certificates of the 7000 dollars till the new gouvernment be establish’d is certainly very good and I will follow it, and prefere land for money. Mr. Jefferson approoves allso much of it, and the more so as he thinks the new gouvernment is allready adopted, by the plurality of states. He thinks the value of paper currency will soon increase and that the States will grant about an aker for every dollare borrow’d. Now, as there was never any interest payd of my 7000 dollares, rated at 6 per cent, the capital must now   nearly doubled. Thus he computes I may very likely got for every dollar or the whole sum an aker. If this shoiuld be the case I may possibly send some more money to purchase more land. But I should like first to know thereabout, how much land could be got by a certain sum remitted by a bill of exchange.

As the time to dispatch the packet is but short, I will not be able to add more reflexions on that head. I need not tell you who   you make me by whriting me a lettre, as every one of them gives me the greatest pleasure and reflect upon me an additional honour and importance. Your reflexions on the present Turkish ware being very pointed pleased every one to whom I showed them, but they would have made a contrary impression on those souverains, who are not free from ambition of glory.

Mr. Paradise, which whom I dined yesterday, gave me the happy news he saw you in good health in the month of April last. May you injoye still many years in good health and see your Country settled on a basis of good law and enjoying peacably that happiness, which it ows to your services. I am with great respect Your most obedient humble servant and old friend

Letters sent to the care of Mr. Jefferson will come to hand, as he will know where I am. The power of atorney is signed by Mr. Jefferson, and two American gentlemen, which will certainly be sufficient, the more so as all acts and powers of atorney signed by the brittish ministre here have their full effect in Brittain.
to his Excellency Benj. Franklin president of the Executif Council of Pensylvania at Philadelphia
