Concerning the writer I have gathered the following particulars: they are to some extent derived from statements scattered up and down his works. For the references to _Notes and Queries_ I am particularly indebted to Mr. W. R. Morfill, the distinguished Reader in Slavonic at the University of Oxford. Our Gyll was born on August 1, 1803 (_History of Wraysbury_, p. 100), being the third son of William Gill (at one time an officer in the army), and the grandson of a City alderman. William Gill, the elder, was a partner in the firm of Wright, Gill, and Dalton, wholesale stationers in Abchurch Lane, London. He was elected alderman in 1781, served as Sheriff in 1781-1782, was appointed Treasurer of Christ's Hospital in 1784-1785, and in due course became Lord Mayor for 1788-1789. He died in the Treasurer's house at Christ's Hospital on March 26, 1798, being then seventy-four years of age: his brother-in-law and partner, Thomas Wright, died on April 9, 1798. An obituary note in _The Gentleman's Magazine_ (vol. lxviii., p. 264) states that the elder William Gill "was a respectable tradesman and died immensely rich." The younger William Gill died on February 16, 1806, at the age of thirty-one. I do not know to what school Gordon Willoughby James Gill was sent. He speaks of himself as "a member of the University of Oxford" (_A Tractate on Language_, First Edition, p. iii.). This is confirmed by the appended note in the Matricula Book, which am enabled to print through the kindness of my friend Mr. H. Butler Clarke:-- "From the Register of Matriculations of the University of Oxford. 1822 Jan. 15. Coll. Pemb. Gordon Willoughby Jacobus Gill, 18, Gulielmi, de par. S. Mariæ bonæ Arm. fil. 3^{ius}. A true extract, made 30 Jan^{y.}, 1903 by T. Vere Bayne, Keeper of the Archives."
