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

"Let posterity know, and knowing, be astonished, that on the
fifteenth day of September, 1784, Vincent Lunardi of Lucca, in
Tuscany, the first aerial 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

chemistry and the fortitude of man, that improvement in science,

(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

In answer to the above, your correspondent will find two articles in the
