NOTES AND QUERIES.

PHOTOGRAPHIC COKBESPONDENCE. 



Precision in Photographic Processes. — I have 

 for a long period observed, and been much an- 

 noyed at the circumstance, that many of your 

 photographic correspondents are very remiss when 

 they favour you with recipes for certain processes, 

 in not stating the specific gravity of the articles 

 used ; also, in giving the quantities, in not stating 

 if it is by weight or measure. 



To illustrate my meaning more fully, I will 

 refer to Vol. viii., p. 252., where a correspondent, 

 in his albumen process, adds " chloride of barium, 

 7j dr." Now, as this article is prepared and sold 

 both in crystals and in a liquid state, it would be 

 desirable to know which of the two is meant before 

 bis disciples run the risk of spoiling their paper 

 and losing their time. 



How easy would it be to prefix the letter f 

 where fluid oz., dr., or other quantity is meant. 



Trusting that this hint may in future induce 

 your correspondents to be as explicit as possible 

 on all points, believe me to be an 



Amateur Photographer. 



Tent for Collodion. — As I have frequently be- 

 nefited from the hints of your correspondents, I 

 in my turn hasten to communicate a very simple 

 plan I have contrived for a portable tent for the 

 collodion process, in the hope it may be found to 

 answer with othei'S as well as it has done with me : 

 it is as follows. 



Kound the legs of my camera stand (a tripod 

 one) I have made a covering for two of the sides, 

 of a double lining of glazed yellow calico, with a 

 few loops at the foot to stake to the ground ; the 

 third side is made of thick dark cloth, much wider 

 and larger than to cover the side, which is fastened 

 at one leg of the stand to the calico. The other 

 side is provided with loops to fasten to correspond- 

 ing buttons on the other leg, and by bending on 

 my knees I can easily pull the dark cloth over 

 my head and back, fasten the loops to the buttons, 

 and then I can perfectly perform any manipulation 

 required, without the risk of any ray of white 

 light entering ; and certainly nothing can be more 

 portable. 



The simplicity of the thing makes any farther 

 description of it unnecessary, to say nothing of 

 your valuable space. Jan. 



Mr. Sisson's Developing Solution. — The Eev. 

 Mr. Sisson, in a letter I received from him a few 

 days ago, stated that he had been trying, at the 

 recommendation of a gentleman who had written 

 to him upon the subject, a stronger developing 

 solution than that the formula for which he pub- 

 lished some time back in your pages, and that it 

 gave splendid positive pictures with very short 

 exposure in the camera. 



Since I received his letter I have been able to 

 corroborate his testimony in favour of the stronger 

 solution, and have much pleasure in sending you 

 the formula for the benefit of your readers. It is 

 this : 1^ drachms of protosulphate of iron in five 

 ounces of water, 1 drachm of nitrate of lead, 

 letting it settle for some hours ; pour oif the clear 

 liquid, and then add to it 2 drachms of acetic 

 acid. J. Leachman.

Mr. Stewarts Pantograph. — Will some of your 

 photographic readers, who may know the proper 

 size of Mb. Stewabt's pantograph, give a detailed 

 description of it ? We should have focal length 

 of lens, size of box, and the length of the sliding 

 parts of it. Cannot the lens be made fast in the 

 middle of the box, provided the frames can be 

 adjusted for difierent- sized pictures? R. Elliott.

George Broicne of Shefford (Vol. viii., p. 243.). 

 — I observe that in your interesting publication 

 you have inserted the Query which I sent you 

 long since. A somewhat similar Query of mine 

 has already appeared, and been answered by your 

 correspondents II. C. C. and T. Hughes ; the 

 latter stating that my particulars are not strictly 

 correct, inasmuch as the individual styled by me 

 as " Sir George Browne, Bart." was in reality 

 simple " George Browne, Esq." I admit this 

 error ; but if I was wrong Mb. Hughes was so 

 too, for George Browne's wife was Eleanor, and 

 not Elizabeth, Blount, as appears by his affidavit 

 in the State Paper Office, wherein he deposes that 

 he " had by JEllinor, his late wife, deceased daugh- 

 ter of Sir Richard Blount, eight sons, namely, 

 George, Richard, Anthony, John, William, Henry, 

 Francis, and Robert, and seven daughters." 



The sons are thus disposed of : 



1. George, created K. B. at the coronation of 

 Charles II. ; married Elizabeth Englefield ; had 

 issue two daughters ; died 1678. 



2. Richard, a captain in the king's army, 1649, 

 and was dead in 1650. 



3. Anthony, who was " preferred to the trade 

 of a Merchant," 1650. 



4. John, a page to Prince Thomas, uncle to the 

 Duke of Savoy ; created Bart. 1665 ; married 

 Mrs. Bradley ; had issue. 



5. William, had a " reversion of a copyhold in 

 Shefford." 



6. Henry, died unmarried, 1668 ; buried at 

 Shefford. 



7. Francis, nine years old in 1651 ; and 



8. Robert, four years old in 1651. 



In that year (1651) Henry, Francis, and 

 Robert were living with their guardian, Mr.
