NOTES AND QUERIES. 



[No. 157 



effect is produced by the double wash, and by the 

 entire immersion of the paper in the solution of 

 iodide of potassium. 



It may be here observed that the solution of 

 iodide of potassium may be preserved, filtered, 

 and used again and again as long as any remains. 



3. Iodized paper cannot well be over-soaked, 

 but it is perfectly immaterial whether the water is 

 often changed or not, so long as the paper is freed 

 from the soluble salts. 



4. The superfluous aceto-nitrate of silver should 

 be well blotted off, but it is by no means ne- 

 cessary to make it perfectly dry, for the amber 

 varnish will effectually preserve the negative. 



5. Certainly. 



6. The fact of the picture having been suffi- 

 ciently saturated is determined by its showing 

 itself clear and transparent when held up to the 

 light. When it has not been immersed sufficiently 

 long, blotches will appear, which requii'e decom- 

 position by the hyposulphite of soda. A picture 

 may always be overprinted, as it may be toned 

 down by the hyposulphite. 



Uniformity of Tint in Collodion Pictures. — 

 This object, which has so long been desired by all 

 who practise photography, may be obtained by 

 developing with a mixture of fresh-made proto- 

 nitrate of iron (made according to the formula 

 given by Dr. Diamond in "N. & Q.," No. 152., 

 p. 295.) and pyrogallic acid, in the proportion of 

 six drops of pyrogallic acid to one drachm of 

 protonitrate of iron, which quantity will be found 

 in most oases sufficient to develope an ordinary- 

 sized plate. 



It may be added as another advantage from the 

 use of these definite portions, that the tint pro- 

 duced is of a bright silvery grey, whicb is equally 

 agreeable by candle-light as by daylight.

Collodion and its Application to Photography 

 (Vol. iv., p. 443.). — Some months ago a question 

 was asked in your columns as to the origin of the 

 name of collodion, and who first recommended the 

 use of it in photography, but which, I believe, has 

 never been replied to. As "N", & Q." has now 

 become a regular photographic medium, I hope 

 that somebody will answer not only your former 

 querist, but also Q. Q. 



Photographic Pictures for the Magic-lanthom. — 

 Your articles on " Photography" have much in- 

 terested and instructed me. Would you permit 

 me to inquire if any of your correspondents could 

 describe a method by which magic-lanthom slides 

 might be prepared photographically ? I have suc- 

 ceeded in copying by the collodion pi'ocess some 

 beautiful engravings, and should be glad to know 

 how to make them available as above. Could they 



not be copied from the glass pictures by the col- 

 lodion process in some such way as paper posi- 

 tives are taken from negatives — hy printing ? I 

 have made some attempts, and have succeeded In 

 getting impressions by gas-light in two seconds ; 

 but, unfortunately, have always damaged the film 

 in the operation. 



Would albumen answer better than collodion ? 

 Information on the above points would be highly 

 valued by, no doubt, many of your readers, as well 

 as by E. S- 



P.S. I do not know if I have expressed myself 

 quite clearly. — Having several glass pictures (col- 

 lodion photographs), I want to learn how I might 

 copy them, so as to use them in the magic-lanthorn. 

 At present, they show negatively when used as 

 slides — the lights and shades being reversed. 

 Copies printed from them would, of course, show 

 positively. How to get the copies is my difficulty* 



Manchester, Oct. 20. 1852. 



Shahspeare's MSS. (Vol. vi., p. 339.).— Henry 

 Earl of Southampton was the friend and patron of 

 Shakspeare, and it is very probable that, if inqui- 

 ries were made amongst the representatives of 

 the last Earl of Southampton, or his executors, 

 letters from Shakspeare, or some of his MSS., 

 might be found. G-. 



Authorship of " Bombastes Furioso " (Vol. vi., 

 p. 286.). — Allow me to inform your correspond- 

 ent Nemo that the farce of Bombastes Furioso was 

 published In 1830 by the late Thomas Rodd, who- 

 was not likely to be In error when he (sanctioned 

 by that gentleman) placed upon the title-page the 

 name of William Barnes Rhodes as Its author. 

 A slight biographical sketch accompanies the 

 ■vvrork. Thomas H. Lacy. 



The Oak of Reformation (Vol. vi., p. 254.). — 

 In reply to Tee Bee's question as to the existence 

 of the " Oak of Reformation," I can assure him 

 that It stands on the footpath of the turnpike road 

 leading from Wymondham to Norwich ; and 

 though the stem is hardly more than a mere shell, 

 it still throws out leaves every spring. Kett was 

 a Wymondham man, and there is a tradition that 

 on some occasion he hid himself from his pursuers 

 in the branches of the " Old Oak," as it Is always 

 called by the Wymondham and Hethersett people. 

 I believe that it is in this last-named parish that 

 the tree stands. East Anglia. 



Chantry Chapels (Vol. \i., p. 223.). —There is 

 at Swallowfield, near Reading, a sepulchral chan- 

 try chapel. It appears, from an extract from 

 Rymer's Feedera, vol. I. part ii., that a bull was 

 granted to John le Despencer, a. d. 1256, 40
