Notices to Correspondents.

J. M. G., _who writes respecting the Leigh Peerage, is informed that we

have a private letter for him. How can it be addressed to him?_

W. W. (Malta) _has our best thanks for his letter of the 25th of June. His

suggestion will be adopted; but we shall shortly have the pleasure of

addressing a_ private _communication to him._

SHAKSPEARE CRITICISM. _We have to apologise to many friends and

Correspondents for the postponement of their communications. As Soon as the

Index to_ Vol. vii. _is published, we shall take steps to get out of these

arrears._

C. P. F. _The_ Ch _in the name of _Ch_obham is soft. There is a _C_obham

within a few miles of the Camp._

IODIDE (June 24th). _There is much care required in iodizing paper; we have

no hesitation in saying at present the subject has not met with sufficient

attention. When the iodized paper is immersed in water, it is some time

before it assumes a yellow colour. This may be accelerated by often

changing the water. The brightness of the colour is by no means an index of

its degree of sensitiveness--on the contrary, paper of a bright yellow

colour is more apt to brown than one of a pale primrose. Too bright a

yellow would also indicate an insufficient soaking; and suffering the paper

to remain longer than is needful not only lessens its sensitive powers, but

does much damage by removing all the size._

H. N. (Kingston). _Violet-coloured glass, ground on one side, may be

obtained at 11d. per square foot of Messrs. Forest and Brownley, Lime

Street, Liverpool. It may also be had in London, but the price charged is

much higher. This glass obstructs just a sufficient degree of light, and is

most agreeable to the sitter; not much advantage accrues from the use of

large sheets, and it is objectionable for price. No doubt such an

application as you mention would be useful; but, from the difficulty there

is in keeping out the wet from a glass roof, it would be very

objectionable. Beyond a reference to our advertising columns, we cannot

enter upon the subject of the prices of chemicals and their purity. In

making gun cotton, the time of immersion in the acids must be the same for

twenty grains as for any large quantity: when good, there is a peculiar

crispness in the cotton, and it is_ quite _soluble in the ether. If our

Correspondent (who expresses so much earnestness of success) will forward

his address, he shall receive a small portion made according to_ DR.

DIAMOND'S _formulary, which we find extremely soluble; and he can compare

it with that of his own production._

F. M. (Malta). _1st. We are informed by_ DR. DIAMOND _that however

beautiful the results obtained by others in the use of Canson's paper, in

his hands he has found no certainty in its action, and, for iodized paper

for negatives, far inferior to the best English papers. If the salts of

gold are to be used, deep tints are very readily obtained by the French

papers. The propriety of using gold is very questionable, not only as

affecting the after permanence of the picture, but from the strong

contrasts generally produced being very offensive to an artist's eye.

2ndly. Xyloidine may be iodized precisely the same as collodion, but no

advantage whatever is gained from its use. A collodion for the taking of

positives on glass should be differently made to one for negative pictures.

There should be less of the iodides contained in it, and it should be more

fluid. When this is the case, the image is never washed out by the hypo.,

and the delineation is equal in minuteness to any Daguerreotype on metal

plates, as has been shown by the specimens of the reduction of printing

exhibited by Mr. Rosling at the Society of Arts' Exhibition, where the

letters were reduced to 1-750th of an inch, or less than half the diameter

of a human hair. If the protonitrate of iron_ properly prepared _be used in

the development, the deposit assumes the beautiful appearance of dead white

silver, having none of the reflecting qualities of the metal plates._

C. E. F. (June 13th). _The spots in the specimen sent depend upon minute

substances in your collodion not receiving the action of the nitrate of

silver bath; and you will find this upon looking through a prepared plate

after it has been in the nitrate bath, and previously to its ever having

been in the camera. They may be iodide or iodate of silver, or small

crystals of nitrate of potash. If the former, add a little piece of iodide

of potassium, say ten grains to two ounces of collodion; or if the latter,

it would depend upon a defective washing of the gun cotton by which all the

soluble salts have not been removed: thus more care must be used. We would

recommend you to use an entirely new bath and stronger, four ounces of

hypo. to a pint: it is evident that your very nice specimens have been

spoiled by the stains of the bath. Allow us again to draw your attention to

the process given by_ MR. POLLOCK; _we have seen most satisfactory pictures

produced by it._

R. H. CHATTOCK (Solihull). _The "freckled" appearance which you mention in

your positives in all probability depends upon the action of the light upon

the silver, which still remains in your proof. We have often found it to be

the case when old hyposulphite of soda is used, and when the strength of

the bath is becoming weak and doubtful. It is certainly a safe process to

soak the picture in clean water for an hour or two,_ the light being

excluded _previous to the immersion into the hypo.; and the water

extracting a large portion of the solutions remaining on the paper, the

after application of the hypo. need not be so long continued, whereby the

tone of the picture is not so much lowered. Your own observation, that a

piece of Whatman's paper being merely divided, and one point exhibiting the

defects and the other not, at once negatives the idea that the size in the

paper has been affected._

_The_ Index _to our_ SEVENTH VOLUME _will be ready on Saturday next, the

16th._

_A few complete sets of_ "NOTES AND QUERIES," Vols. i. _to_ vi., _price

Three Guineas, may now be had; for which early application is desirable._

"NOTES AND QUERIES" _is published at noon on Friday, so that the Country

Booksellers may receive Copies in that night's parcels, and deliver them to

their Subscribers on the Saturday._
