I heard yesterday, by accident, that an honorable gentleman in Congress had made a calculation from the general account, which I gave in my narrative of the price of the clothes purchased in France, and that given by M. Holker, in a memorial of his, and had drawn consequences very injurious to me therefrom. In my narrative I informed Congress that the clothes cost 32s. or 33s. sterling complete, delivered on board. This was nearly the average price, and of that, and not of the particular, I spoke. 32s. sterling is equal to 36 livres, 11 sols, 5 deniers. The clothes bought of Messrs Sabbatier and Desprez cost 36 livres nearest, delivered on board; those of Mons. Monthieu a few sols more; those by Mr Williams, the same, nearly as I recollect; and about a thousand suits of M. Coder, of a different fashion, more than 40 livres each. I have before related to Congress, that Mr Lee himself approved of these purchases, having been present at the contracting for a part of them, those of M. Coder in particular, and had signed the settlement of the accounts, and orders or draughts for the money. Surprised at the calculation made, and the injurious inferences drawn therefrom, I wrote to M. Holker the enclosed letter, and received his answer thereto, a copy of which I take the liberty of enclosing. 37 livres being equal to 32s. 4-1/2d. sterling, it is evident that the calculation made is wrong, even if I had fixed the price positively at 32s. or 33s. sterling. I will not trouble Congress at present with any further observations on the subject, But am, with much respect, &c. SILAS DEANE. * * * * * TO M. HOLKER. Philadelphia, 26th April, 1779. Sir,
