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 lath of 

 June. His suggestion loill be adopted ; but we shall shortly have 

 the pleasure of addressing a private comtnunication to htm. 



Shakspe^re Criticism. JVe 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 Chobham is soft. There is a 

 Cobham within a few miles of the Camp. 



Iodide (June 24th). There is much care required in iodizing 

 Doner ■ we have no hesitation in saying at present the subject has not 

 met with sufficient attention. When the iodized paper ts immersed 

 in water, it is some time before it assumes a yellow colour, litis 

 may be accHeraled by often changing the water. The brightness 

 of the colour is by no means an index of Us 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, 

 iut does ?nuch damage by removing all the size. 



H "V. (Kingston). Violet-coloured glass, ground on one side, 

 may be obtained at lid. per square foot of Messrs. Forest and 

 Brownley, Lime Street, Liverpool. Jt may also be had m 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 

 mich 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 m 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 t/ie acids must be the 

 same for twenty grains as for any large quantity: when good, 

 there is a peculiar crispness in the cot ton, and it is qmte soluble m 

 the ether. If our Corres^pondenl {who expresses so much earnest- 

 ness of success) will forward his address, he shall receive a small 

 portion made according to Dr. Dikmo^o' s formulary, which we 



find extremely solubles "fx^ ''^ <^"f* compare it with that of his 

 own production. 



F. M. (Malta). \sl. 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 certainly 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 aff.cling 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 pn 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 minute- 

 ness to any Daguerreotype on tnetal 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 tellers were reduced to 

 X-lhOth of an inch, or less than half the diameter of a human hair. 

 Jf the protonitrate of iron properly prepared be used in the de- 

 velopment, the deposit assumes the beautiful appearance of dead 

 white silver, having none qf 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 Ihc 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 catnera. They may be iodide 

 or iodate of silver, or small crystals of nilrate 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 taould 

 recommend you to use an entirely new halh and stronger, four 

 ounces of hypo, to a pint : it is evident that your very nice speci- 

 mens 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 tlie case when old hypo- 

 sulphite of soda is used, and when the strength of the bath is 

 becoming weak and doublful. 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, thata piece of Whatman's paper being merely di- 

 vided, and one point exhibiting the defects and the other not, at 

 once negatives the idea that the size in the paper has been effected. 



The Index to our Seventh Volume will be ready on Saturday
