_Dog Latin_.--The answer of one of your late correspondents (E. M. B., Vol. vii., p. 622.) on the subject of "Latin--Latiner," has revived a Query in your First Volume (p. 230.) as to the origin of this expression which does not appear to have been answered. I do not remember having seen any explanation of the term, but I have arrived at one for myself, and present it to your readers for what it is worth. Nothing, it must be admitted, can be more inconsistent with the usual forms of language than the Latin of mediaeval periods; it is often, in fact, not Latin at all, but merely a Latin form given to simple English or other words, and admitting of the greatest variety. Now of all animals the distinctions of breed are perhaps more numerous in the canine race than any other. The word "mongrel," originally applied to one of these quadruped combinations of variety, has long been used to signify anything in which mixture of class existed, especially of a debasing kind, to which such mixture generally tends. Nothing could be more appropriate than the application of the term to the "infima latinitas" of the Middle Ages; and from "mongrel" the transition to the name of the genus from that of the degenerate species appears to me to be very easy, though fanciful. J. B--T. _Thomas Wright of Durham_.--In the _Philosophical Magazine_ for April, 1848, I gave an account of the "Original Theory or new Hypothesis of the Universe" of Thomas Wright, whose anticipations of modern speculation on the milky way, the central sun, and some other points, make him one of the most remarkable astronomical thinkers of his day. In the biography in the _Gentleman's Magazine_ for 1793, he is described as struggling for a livelihood when a young man, and no account is given of the manner in which he obtained the handsome competence with which he emerges in 1756, or thereabouts. A few days after my account was published, I was informed (by Captain James, R.E.) that a large four-foot orrery, constructed by Wright for the Royal Academy at Portsmouth, was still in that town; and that by the title of "J. Harrises Use of the Globes" it appears that he (Wright) kept his shop at the _Orrery_, near Water Lane, Fleet Street (No. 136), under the title of instrument-maker to his Majesty. In an edition of Harris (the 8th, 1767), which I lately met with, the above is described as "late the shop of Thomas Wright," &c. By the advertisements which this work contains, Wright must have had an extensive business as a philosophical instrument-maker. The omission in the biography is a strange one. Possibly some farther information may fall in the way of some of your readers. A. DE MORGAN. _A Funeral Custom_.--At Broadwas, Worcestershire, in the valley of the Teame, it is the custom at funerals, on reaching "the Church Walk," for the bearers to set down the coffin, and, as they stand around, to bow to it.
