nearly six hours), when, much to my chagrin, I found on their removal that
they had all, more or less, become browned, or, rather, had taken on a
dirty, deep, nankeen colour, those that had been first floated being
decidedly the worst. I had previously thought that the papers _must_ be
left _at least_ two and a half to three hours, a longer period having no
other effect than that of softening the papers, or, at most, of allowing
some slight portion of the iodide to fall off from their surface, whereas,
from the above-described discoloration, an evident decomposition must have
commenced, which I am quite at a loss to account for; neither can I
conjecture what the chemical change can have been. I have several times
before prepared good papers in trays filled with water from the same
stream, but from the quantity running in the brook in the spring months, I
never before have had the chance of floating them in the stream itself.

An explanation of the above difficulty from some obliging and
better-informed photographist would be very thankfully received by

HENRY H. HELE.

Ashburton, Devon.

P.S.--The pool of water was well shaded, consequently not a ray of bright
sunlight could possibly impinge on the papers while floating.

I have always understood that _pure_ iodide of silver was quite insensible
to the action of light, or to any other chemical change, as far as the
action of atmospheric air was concerned.

_Bishop Frampton_ (Vol. iii., p 261.).--For some account of this excellent
man, see chapter xxxi. of Mr. Anderdon's _Life of Bishop Ken_, where are
given some very interesting letters, that are printed from the MSS. in the
possession of Dr. Williams, Warden of New College, Oxford. Frampton appears
to have been at one time chaplain to the British Factory at Aleppo.
Mandeville, in the Dedication prefixed to his _Journey from Aleppo to
Jerusalem_, makes honourable mention of him, and attributes the highly
creditable character of the society to the influence of that incomparable
instructor. When the funeral procession of Christian, Countess of
Devonshire, halted at Leicester, on the way to Derby, a sermon was preached
on the occasion by Frampton, who was then chaplain to the Earl of Elgin,
the Countess's near relative. In sending these scraps, allow me to express
the hope that MR. EVANS has not laid aside his intention of favouring us
with a Li
