Pasquin — Tobacco- smoking (Vol. x., pp. 46.48.). 

 — Was it not on the occasion of the Pope's pro- 

 hibition of tobacco-smoking, that Pasquin ap- 

 peared hohling on a scroll the following very 

 pertinent quotation from the Book of Job : 



" Contra folium quod vento rapitur ostendis potentiam 

 tuam, et stipulam siccam persequeris ? "

Talbotype Queries : — 



1. In iodizing paper according .to Dr. Diamond's in- 

 structions, as given in " N. & Q.," Vol. viii., p. 600., is it 

 absolutely necessary to wash it for four hours, or can the 

 time be reduced by often changing the water ? Does not 

 the long soaking remove the size ? 



2. In making the iodized paper sensitive, should the 

 gallo-nitrate of silver be blotted off immediately after its 

 application, or should it be allowed to soak in for some 

 time ; and if so, for how long ? 



3. If the sensitive papers are put into the dark slide 

 dry, is it necessary to wash the glasses before putting in 

 fresh papers ? 



4. What is the cause of brown spots appearing on the 

 back of the picture after developing, and how is this to 

 be prevented ? 



5. Can good pictures be obtained upon new paper, as I 

 cannot meet with any old ? R. 



[1. It may not be absolutely needful to wash the paper 

 for four hours, but it is safe to do so ; the better and more 

 compact the paper, the longer the soaking required. Cold 

 water does not appear to remove the size of the paper. 

 We have used perfectly good iodized paper, which has 

 been soaked twenty-four hours. 



2. After the paper has been well wetted with the gallo- 

 nitrate solution, it is not needful for it to soak, but im- 

 mediately blot it off. Take care that the solution is 

 applied perfectly all over up to the edges, which prevents 

 the paper from cockling up. 



3. When your glasses have been once well cleaned, 

 never wash them, but breathe and rub with a silk hand- 

 kerchief. Papers are better put in at once after blotting 

 off; they always lay flat when that is the case. 



4. The spots in all probabiUty arise from some of the 

 solution staining the back : or, if you develope a paper 

 which has been used for waxing the negatives, it some- 

 times causes it. New paper will act often in this way 

 from permitting the solutions to permeate through. 



_ 5. Pictures can be obtained on new paper, but we be 

 lieve much uncertainty then attends the process. Those 

 ■who have old paper should value it : often paper obtained 



from the ordinary stationers, is much better than that 

 made for photographic purposes. The stationers in local 

 towns have often old stock they are glad to get rid of, 

 and it is invaluable for photography. We recently pur- 

 chased a most valuable article in this way for our own 

 use.] 



Bromide of Silver. — The addition of bromide of silver 

 to the double iodide solution, as was some time back re- 

 commended by Dk. Diamond for increasing the sensi- 

 tiveness of paper prepared with it, cannot, I think, be any 

 advantage whatever, for not one particle of bromide of 

 silver is thereby introduced into the paper, as the follow- 

 ing experiment will show, namely : if a portion of bro- 

 mide of silver, prepared by precipitation from the nitrate, 

 is boiled in a nearly saturated solution of muriate of am- 

 monia, it will be found entirely to dissolve ; whereas the 

 precipitate, which forms on adding water to a solution of 

 iodide of potassium saturated with bromide of silver, will, 

 if treated in the same manner, be found to be altogether 

 insoluble. The precipitate in the latter case cannot there- 

 fore be bromide of silver ; and, as the only other elements 

 which the solution contained were iodine and potassium, 

 it must evidently be the iodide. But if farther proof is 

 required of this, the precipitate may be boiled in a little 

 strong nitric acid, when a piece of paper moistened with 

 starch paste, on being held in the vapour, will immedi- 

 ately assume a blue colour, indicating the presence of 

 iodine. It appears, therefore, that iodide of silver alone 

 is precipitated on adding water to a solution of the double 

 iodide of silver, which contains also bromide of silver. 

 What then can be the advantage of adding the bromide ?

Queen Anne's Farthings (Vol. x., p. 384.). — 

 It is perfectly astonishing to what an extent the 

 notion of there being but three farthings of this 

 queen (and their consequent excessive value) has 

 spread, even supposing it to have been derived 

 from the story mentioned by Mr. Akerman in 

 Vol. iv., p. 84. Mr. Gantillon's account ap- 

 pears to be a variety of this. Many a time have 

 I had one of the very common little brass pieces 

 of Queen Anne (perhaps a forgery of the six- 

 pence) brought exultingly to me as one of the 

 three, and very rueful has been the expression 

 when I have produced three or four others to 

 prove the contrary. There are five patterns of 

 the farthing : 



1. j^. Britannia as usual, with date 1713 in the 

 legend. Ex. blank. 



2. 5c. as last, but with date 1714 in the ex. 

 Both these are comparatively common, and were 

 probably current. They have a broad milled 

 edge, exactly similar to the farthings of Geo. III. 



3. " Q. ANNA . AVGVSTA." IJi. Peacc in a biga, 

 with an olive branch and the hasta pura or point- 

 less spear in her hand. Ex. 1713. 



4. Obv. as Nos. 1. and 2. Kev. Britannia seated 

 under an arch. Ex. 1713. 



5. Legend of both sides, indented on a broad 

 rim, like the early pennies of Geo. III. Bev.
