NOTES AND QUERIES. 



[No. 228. 



An impression of Colonel Byrd's book-plate, given 

 by a friend, is enclosed. I must add that the 

 pictures at Brandon are at that mansion, through 

 the marriage of Mr. Harrison (a signer of the De- 

 claration of Independence) with the daughter of 

 the third Colonel Byrd. 



I have occupied much more space than I in- 

 tended, but I have said enough I hope to show, 

 1. That it is possible, from dates, from the cha- 

 racter, wealth, and position of Mr. Byrd and Mr. 

 Hill, together with the length of time the pictures 

 have remained in the respective families, for Van- 

 dyke to have painted these portraits. 2. That as 

 men who directed the energies, developed the re- 

 sources, of our infant settlements, who brought 

 hither the products of science, literature, and art, 

 who exhibited the refinements of birth, the graces 

 of good breeding, yet'were always ready to serve 

 their country in the. field or in the council, Mr. 

 Byrd and Mr. Hill are vastly more worthy of com- 

 memoration and reverence than all the Earls of 

 Dredlington that ever sat at his majesty's Board 

 of Green Cloth. J. Baech.

PHOTOGRAPHIC CORRESPONDENCE. 



Cyanide of Potassium It may be interesting to 



your photographic friends to know that cyanide of 

 potassium is capable of replacing hyposulphite of soda 

 in all collodion processes. If used of the strength of 

 five grains to one ounce of water, no danger need be 

 apprehended from it. Its merits are cleanliness, quick- 

 ness of operation, and the minute quantity of water re- 

 quired for washing the picture fixed therewith.

Mode of exciting Calotype Paper. — I forgot inserting 

 this plan of exciting in my paper : it is very clean and 

 convenient, simple and sure. Obtain a piece of plate 

 glass, two or three inches larger than your paper, level 

 it on a table with a few bits of wood, pour on it your 

 exciting mixture (say aceto-nitrate and gallic acid, 

 solution of each 20 minims, distilled water 1 ounce), 

 and spread it evenly over with a scrap of blotting- 

 paper. Float your paper two minutes, remove and 

 blot off; this ensures perfect evenness, especially if the 

 paper is large. You may thus excite half a dozen papers 

 with little more trouble than one.

The Double Iodide Solution — Purity of Photographic 

 Chemicals. — The observations of Ma. Leachman upon 

 the solvent powers of iodide of potassium (Vol. ix„ 

 p. 182.) are perfectly correct, but 1 believe our photo- 

 " graphic chemicals are often much adulterated. The 

 iodide of potassium is frequently mixed with the car- 

 bonate. Dr. Mansell writes me word, in a comment 

 upon your note upon his communication, " What I 

 used was very pure, having been prepared by Mr. Ar- 

 nold with great care : it was some that had gone to the 

 Great Exhibition as a sample of Guernsey make, and 



obtained a medal." I have this day used exactly seven 

 ounces avoirdupois to make a pint of the iodizing 

 solution, which, within a few grains, agrees with my 

 former results. Nitrate of silver, I am informed upon 

 a most respectable authority, has been adulterated 

 thirty percent., and without careful testing has eluded 

 detection ; but I am inclined to think our cheapest 

 article has come in for its largest share of mixture. I 

 have lately perfectly failed in the removal of the iodide 

 of silver with a saturated solution of what I purchased 

 as hyposulphite of soda, but which could have been 

 little else than common Glauber's salts ; for upon ap- 

 plying a similar solution of some which was made by 

 M. Butka of Prague, and supplied me by Messrs. 

 Simpson and Maule, the effect was almost immediate, 

 demonstrating how much we are misled in our con- 

 clusions, from believing we are manipulating with the 

 same substances, when in fact they are quite different.

Hyposulphite of Soda Baths. — Is there any objec- 

 tion to using the same bath (saturated solution of 

 hyposulphite) for fixing both paper calotype negatives 

 and positives printed on albumenized paper from glass 

 collodion negatives ? C. E. F.

Daughters taking their Mothers'' Names (Vol. 

 viii., p. 586.). — Buriensis asked for instances of 

 temp. Edvv. I., II., III., of a daughter adding to 

 her own name that of her mother : as Alice, 

 daughter of Ada, &c. Though I am not able to 

 furnish an instance of a daughter doing so, I can 

 refer him to a few of sons using that form of sur- 

 name some years earlier, but the practice seems 

 very limited. Thus in Liber de Antiquis Legibus, 

 published by the Camden Society, we have, among 

 the early sheriffs of London in 1193, Willielnius 

 filius Ysabelis, or, as in the appendix 222, Ysabel ; 

 in 1200, Willielnius filius Alicie; in 1213, Mar- 

 tinus filius Alicie ; and in 1233 and 1246, Symon 

 filius Marie, — the same person that, as Simon 

 Fitz-Mary, is known as the founder of the Hos- 

 pital of St. Mary Bethlehem Without, Bishops- 

 gate. W. S. W.

The Young Pretender (Vol. ix., p. 177). — Will 

 Ceyrep, or any other correspondent, furnish me 

 with particulars of the Young Pretender's marriage 

 with a daughter of the House of Stolberg ; her 

 name, place of burial, &c. ? She was descended 

 maternally from the noble House of Bruce, through 

 the marriage of Thomas, second Earl of Aylesbury 

 and third Earl of Elgin, with Charlotte (his second 

 wife) Countess of Sannu, or Sannau, of the House 

 of Argenteau. They had a daughter, Charlotte 

 Maria, I suppose an only child, who was married 

 in the year 1722 to the Prince of Horn. These 

 had issue Mary and Elizabeth, whom.also I suppose
