The file comprises two Middlesex deeds apparently unrelated to the Morgan family of Tredegar, unless they relate to the Gould family. One is a surrender by Colonel Samuel Horsey of the palace of Whitehall, Middlesex, to John Ewer of the parish of St Martins in the fields, Middlesex, goldsmith, for £2,000 of one-third of the benefit of letters patent dated 21 July 1726, which granted to William Hinton of the parish of Vauxhall, Surrey, gent., the sole use for fourteen years (according to the statute) of his improvements in the extraction and calcining of the lixiviate salt of wood ash and the ashes of other vegetables by using a mixture of aluminous or vitriolic salt, which might be the means of supplying his majesty's dominions with potash, pearl ash and other fixed salts of ashes, and which letters patent Hinton had sold to Horsey, 1726. The other is a lease for 18 years by John Harison of the parish of Westminster St James, Middlesex, gent., to Henry Bennett of Heath, Oxfordshire, carpenter, of a new-built brick tenement on the south side of Pall Mall Street in the parish of Westminster St James (further described), 1712, endorsed with a sale of the lease to John Ewer of the parish of St Martins in the fields, Middlesex, goldsmith, 1730.
