There appears to be due to Mark & co. for Messrs. de Vernon & Danguard

Besides this, Mark & co. have received from the treasury of the U.S. the interest on 48917/90D from the respective dates at which the sums were placed therein up to the 31st. Dec. 1784. amounting to 1550 Dollars or 8137₶10s. As to the 4691 7/90 Dollars = 24,628₶4s due from the U.S. it bears an annual interest of 281.46 Doll. = 1477₶13s which appears to have been regularly paid. As to the 1823£-5s-4d = 32,818₶16s principal and 632£-16s = 11,390₶8s. interest due from the state of Virginia, I know not the reason why the whole interest and a part of the principal have not been paid; as it appears by the letter of Mr. Bannister and other information I have received that the principal of that debt is in a course of paiment. The whole will probably be discharged in a very few years. I would advise Messrs. Danguard and DeVernon to execute a power of Attorney in the form I send them, leaving a blank for the attorney’s name. That I will send to Mr. Bannister praying him to insert the name of some trust-worthy attorney. This will authorize that attorney to call Messrs. Mark Nephew & co. to account, and in the mean time stay the paiment of any more money to them. If Mark, nephew & co. have not made themselves citizens of any of the American states, this matter will be determined summarily before Mr. Oster the French consul residing in Virginia; but if Mark has made himself a citizen, it must be decided in the courts of justice of the country, in which case it may require a couple of years to settle it. The power of attorney, of which I send a form, must be signed by Messrs. Danguard & de Vernon before a Notary, and there must be a certificate that the person is a Notary, which certificate must be signed by the Prevot de Marchands of Paris with the seal of his office. Besides this, these gentlemen should draw up a full state of their case, and prepare authentic vouchers to support it, and send them to their attorney.
