ON BOOKS, &c.

ABREDONENSIS _must be referred to the_ Philosophical Transactions, vol.
xliii. p. 249., _for a reply to his Query. It will be sufficient here to
state, that the Willingham Boy was at his birth of gigantic form, and an
object of great curiosity to the philosophical world. It is not stated how
long he lived, or what education he received, so that we cannot ascertain
whether he distinguished himself in any "department of literature or art."_

H. N. _will find in our_ Seventh Volume, p. 192., _that the quotation--_

"Perhaps it was right to dissemble your love," &c.,

_is from J. P. Kemble's Comedy of_ The Panel, _altered from Bickerstaff's_
'Tis well 'tis no worse.

MR. POLLOCK'S PROCESS.--"_In answer to_ N. T. B., _a saturated solution of
hypo. saturated with iodide of silver._

"21. Maddox Street. HENRY POLLOCK."

T. B. (Coventry). _Paper positives are seldom varnished. The glossy
appearance which they possess may depend either upon their being printed on
albumenised paper, or upon their being hot-pressed. The latter process
always much improves the picture. Where the size has been much removed, it

gold, and which are now mere shades._

C. M. M. (Abbey Road). _Your question as to the spots has been carefully
answered in a late Number. The film which you notice on the surface of your
nit. silver bath depends upon the remaining portion of ether in the
collodion being liberated, which, not being very soluble in water, causes
the greasy appearance. It soon evaporates, and is of no consequence._

T. COOK _is thanked for his offer of a cheap and easy method of obtaining
pictures for the stereoscope. We shall be glad to receive it._

DR. DIAMOND'S PHOTOGRAPHIC NOTES.--_We share in the desire expressed by_
W. C., J. M. S., _and many other Correspondents, for the speedy publication
of this volume. But we believe the delay is not to be regretted. It is a
very easy matter to write a book upon Photography; but it requires no small
labour, and great consideration, to produce such a volume as_ DR. DIAMOND
_proposes, in which it is his desire to explain everything s
