The book contains printed copies of the depositions of witnesses who beheld Lunardi's descent; and Mr. Baker, who, as a magistrate, took those depositions on oath, to establish what he thought so wonderful a fact, erected on the spot where the balloon descended, in a field near Colliers End, in the parish of Standon, Herts, on the left of the high road from London to Cambridge, a stone with the following inscription on a copper plate. It is still {381} legible, though somewhat defaced. It is engraved in lines of unequal length, but to save your space I have not adhered to those divisions. "Let posterity know, and knowing, be astonished, that on the fifteenth day of September, 1784, Vincent Lunardi of Lucca, in Tuscany, the first aërial traveller in Britain, mounting from the Artillery Ground in London, traversing the regions of the air for two hours and fifteen minutes, in this spot revisited the earth. On this rude monument for ages be recorded, that wondrous enterprise, successfully achieved by the powers of chemistry and the fortitude of man, that improvement in science, which the great Author of all knowledge, patronising by His providence the inventions of mankind, hath graciously permitted to their benefit and His own eternal glory."

"Gwyn," says Mr. Croker, "proposed the _principle_, and in many instances the _details_, of the most important improvements which have been made in the metropolis in our day." Was this copied into the _Literary Gazette_?

(_Suggestions_, &c., 8vo. 1834, p. 23.) J.H.M. Bath. _Gwyn's London and Westminster_ (Vol. ii., p. 297.).--Under this head § N. inquires, "Will you permit me, through your useful publication, to solicit information of the number and date of the _Literary Gazette_ which recalled public attention to this very remarkable fact:" namely, that stated by Mr. Thomas Hunt, in his _Exemplars of Tudor Architecture_ (Longmans, 1830), to the effect that the _Literary Gazette_ had referred to the work entitled _London and Westminster Improved, by John Gwynn_. London, 1766, 4to., as having "pointed out almost all the designs for the improvement of London which have been _devised_ by the civil and military architects of the present day." In answer to the above, your correspondent will find two articles in the _Literary Gazette_ on this interesting subject; the first in No. 473., Feb. 11. 1826, in which it is mentioned that _Mr. Gwynn_, founding himself in some degree upon the plan of _Sir C.
