_Rev. J. Edwards on Metal for Telescopes_.--"T.J." informs the
correspondent who inquired (No. 11, p. 174.) respecting this valuable
paper, that it was printed in the _Nautical Almanac_ for 1787. E.B.
PRICE adds, "_A Treatise on Optical Instruments_, published about twenty
years ago by the Society for the Diffusion of Useful Knowledge, contains
much useful and general information upon this subject; and it is stated
in that work that Mr. Edward's treatise, which is now very scarce, is
republishing in the _Technological Repository_." While "G.B.S."
furnishes the information that the treatise in question may be procured
from Mr. Murray, of Albemarle Street.
_Ordination Pledges_.--In reply to the inquiry of "CLERICUS" (No. 10.,
p. 156.) for manuals containing a complete list of Ordination Pledges,
may be mentioned Johnson's _Clergyman's Vade Mecum_, 2 vols. 12mo., and
William's _Laws relating to the Clergy, being a Practical Guide to the
Clerical Profession on the Legal and Canonical Discharge of their
various Duties_, 8vo. The author of this useful work, which appears not
to have been seen by Lowndes, says, in his advertisement, "The works
which are already extant on Ecclesiastical Law, being either too diffuse
or too concise for ready reference and practical use, the compiler of
this volume has endeavored to remedy this defect by the publication of
the following compendium."
