on._--Will you have the goodness to inquire for me
among your readers and contributors, for the _titles of any works
on_--or references to good _articles in encyclopaedias or dictionaries_
on--or for remarkable isolated passages relating to--_Aerostation_, or
the arts of, or attempts at, flying, either by means of mechanical
wings, &c., or by the aid of balloons.

_Pilgrims' Road to Canterbury._--Can any of the readers of "Notes and
Queries" point out the route which was pursued by Chaucer and his
fellow-travellers on the pilgrimage which his genius has immortalised?
Is the route of the old pilgrims' road laid down upon any early maps?
(it is not, I believe, marked on the Ordnance Survey;) and would it be
possible to traverse it at the present time? Any hints upon these
points, and any references to objects of interest on the line of road
inquired after, will be thankfully received by

Philo-Chaucer.

"_AEdricus qui signa fundebat._"--In a chronicle of Battel Abbey,
compiled in the twelfth century, there is a list of the abbey's tenants
in the town of Battel. Among many such names as Gilbertus Textor,
Godwinus Cocus, Rotbertus filius Siflet, Rotbertus de Havena, I find
that of "AEdricus qui signa fundebat." As this phrase is susceptible of
several widely different renderings, I shall be grateful to any of your
ingenious readers who will give me their opinions as to its actual
meaning. I may add that AEdric was living about the year 1170, so that
the phrase can have no reference to events connected with the battle of
Hastings.

_Osmund the Waterman._--In his description of the _Flowering Fern
(Osmunda regalis)_, Mr. Newman observes, that "the rhizoma [root-stock],
when cut through, has a whitish centre or core, called by old Gerarde in
his _Herbal_, 'the heart of Osmund the waterman.' My lore is
insufficient to furnish my readers with the history of the said Osmund."
(_History of British Ferns_, by Ed. Newman, 2nd ed., p. 334.) Can any of
_your_ readers supply this deficiency?

_Logic._--What is the earliest printed book on logic? meaning the first
which gives the common theory of the syllogism. Does it contain the
celebrated words _Barbara, Celarent_, &c. The difficulty will probably
arise from this, that each book has some _undated_ editions which are
probably earlier than the dated ones. Of books with dates there is the
exposition of Petrus Hispanus by
