NOTES AND QUERIES. 



117 



The history of collodion is (as far as I know) 

 this. In Se])tember, 1850, Dr. Diamond invited 

 nie to meet Mb. Archer at his house, and for the 

 first time Mr. Archer produced some prepared 

 collodion, a portion of which identical sample Dr. 

 Diamond now has in his possession. 



Mr. Archer had then been trying it some five 

 or six weeks. His experiments then went on, and 

 in March, 1851, he published it in the Chemist 

 Let any of your readers procure that Number, 

 and compare Mr. Archer's claim with Le Gray's, 

 who, in 1852, states that he published it in 1850, 

 and gave " the best method that has been dis- 

 covered up to the present time ;" and yet, singu- 

 larly enough, in his edition of 1851, leaves out this 

 best incthod entirely. W. Brown.

Developing Paper Pictures with Pyrngallic Acid, 

 Sfc. — Have any of your photographic correspon- 

 dents tried developing their paper negatives with 

 pyrogalllc acid ? If so, perhnps he would favour 

 the readers of " N. & Q." with the result of his 

 experiments. 



In Dr. Diamond's process for paper negatives, 

 he says the paper, after the iodizing solution has 

 been applied, must be dried before soaking in 

 water. I wish to ask whether it may be dried 

 quickly by the fire, or must it be dried sponta- 

 neously by suspension, &c. ? Again, how long 

 must the paper remain on the sensitive mixture : 

 must it be placed on the sensitive solution, and 

 immediately taken off and blotted, or placed on 

 the sensitive solution, and after some time (what 

 time ?) taken off" and immediately blotted ? 



Have any of your readers substituted iodide of 

 ammonium for iodide of potassium, in preparing 

 paper, collodion, &c., and with what success? 

 And have they substituted nitrate of zinc for 

 glacial acetic acid, as recommended in a French 

 work, with any success ? H. J. F.

Waterloo (J iA. vii., p. 82.). — P. C. S. S. con- 

 ccives that it may be interesting to Philobiblion 

 to learn that the greatest man in the world was not 

 ignorant of the passage in Strada regarding Water- 

 loo, to which Philobiblion refers. From a diary 

 kept for some years, it appears that on Saturday, 

 the 30th of October, 1843, P. C. S. S., who was 

 then on a visit at Walmer Castle, had the pleasure 

 of directing the Duke of Wellington's attention to 

 the passage in question, as translated by Du Ryer 

 (Paris, 1665). He well remembers that the Duke 

 seemed to be greatly struck with It ; that he more 

 than once referied to it, in subsequent conversa- 

 tions ; and that on the following day he requested 

 P. C. S. S. to furnish him with a transcript, which 



he doubts not might still be found among the 

 Duke's papers. P. C. S. S. 



Your correspondent Philobiblion has been led 

 into a double error by a similarity of name. The 

 pagus Waterloeus mentioned by Strada is the 

 French village of Wattrelo, in the modern De- 

 partement du Nord, about six miles to the north- 

 east of Lille. J. S.

Irish Peerages (Vol.vi., p. 604.). — The book 

 alluded to by D. X. as professing to give pedigrees 

 of ennobled Irish families, may be the contempt- 

 ible Letters to George IV., by Captain Rock, a 

 miserable attempt at a continuation of Moore's 

 Memoirs of that mystic personage. Some half of 

 the former book contains libellous notices of the 

 " low origin " of the Irish nobility. Can your 

 correspondent refer me to the play in which there 

 is some sneer that " the housemaid is cousin to an 

 Irish peer?" H. 



Martha Blount (Vol. vii., p. 38.). — An engrav- 

 ing of this lady, from " an original picture, in the 

 collection of Michael Blount, Esq., at Maple- 

 Darham," is prefixed to the tenth volume of 

 Pope's Worhs by Bowles, 1806. W. A. 



In reply to Mr. A. F. Westmacott (Vol. vii., 

 p. 38.), I have, in my collection of engraved por- 

 traits, one of the subject of his inquiry, " Martha 

 Blount." It is in stipple, by Picart, after a picture 

 by Gardner. I have no idea the portrait is rare, 

 and think your correspondent may easily procure 

 it among the printsellers in London. J. Burton. 



Quotations wanted (Vol. vii., p. 40.). — Bacon, in 

 his Essay " Of Studies," has this sentence : 



" And if he read little, he had need have much cun- 

 ning, to seem to know that he doth not." 



which is perhaps the reference Miss Edgeworth 

 intended. 



" A world without a sun," is from Campbell's 

 Pleasures of Hope, Part II. line 24. : 



" And say, without our hopes, without our fears, 

 Without the home that plighted love endears, 

 Without the smile from partial beauty won, 

 Oh ! what were man ? — a world without a sun." 



I beg to add a parallel from Burns : 



" What is life, when wanting love ? 

 Night without a morning : 

 Love's the cloudless summer sun, 

 Nature gay adorning." 



See the song beginning : 



" Thine am I, my faithful fair."

 East Sheen, Surrey.
