_Mounting Photographs_ (Vol. ix., p. 282.).--J. L. S. will find the
"Indian-rubber glue," which is sold in tin cases, the simplest and cleanest
substance for mounting positives; it also possesses the advantage of being
free from the attacks of insects.

_Books on Bells_ (Vol. ix., p. 240.).--Add to MR. ELLACOMBE'S curious list
of books on bells the following:

"Duo Vota consultiva, unum de Campanis, alterum de Coemeteriis. In
quibus de utriusque antiquitate, {311} consecratione, usu et effectibus

in praxi, hac de re occurrentium decisionem, non injucunde adducuntur.

I have here given the full title of a pamphlet of 112 pages, exclusive of

Bodleian catalogue, nor was it in Mr. Douce's library.

_Medal in Honour of Chevalier St. George_ (Vol. ix., p. 105).--A. S.
inquires about a medal supposed to have been struck in honour of Prince
James (Chevalier St. George); but his account of it is so vague, that I am
unable to answer his question. If he will describe the medal, or state the

_Dean Swift's Suspension_ (Vol. ix., p. 244).--I am surprised that ABHBA
should express a belief that the circumstances of Swift's college
punishment have not been noticed by _any of his biographers_, when every
syllable of his communication is detailed (with original documentary
proofs) in Dr. Barrett's _Early Life of Swift_, an
