[Now that the serial issue of this Index is approaching completion,
we take the opportunity of announcing that we propose to
issue it in a separate form. Our plan has somewhat extended itself
as the work has proceeded, and no one can be more fully aware
than we are ourselves of the numerous imperfections in our records,
especially in the early part of the alphabet. We hope, therefore,
that everyone who can will kindly send us any corrections or
additions they may have noted as to what has already appeared, as
well as any information as to names not as yet reached. We propose
bringing the work as completely as wc can down to date at
the end of the present year, and issuing it early in 1891, bound in
cloth, at 3s. (5d. per copy, to subscribers whose names are received
before publication, the published price being G.s. Intending subscribers
should send their names, but not the amount of aubbcription,
to the Editor of this Journal, care of the Publishers, 5-1, llatton
Garden, E.G. Due notice will be given when the volume is ready
for distribution.]
