NOTES AND QUERIES.

than to my emblematical shelf, und may be worth 

 u separate Note hereafter. 



Under the name of Farlie, or Fairlie, Me. Corser 

 mixes up the titles of two distinct books ; they are 

 now before me, and divide themselves thus : 



1. " L^clinocavsia, sive Moralia Facvm Emblemata. 

 Light's Moral Emblems. Authore Roberto Farlajo, 

 Scoto-Britanno. 12mo. : London, Th, Cotes for M. 

 Sparke, 1G38." 



Containing fifty-eight emblems in Latin and En- 

 glish, each with a cut, with a dedication in Latin 

 to the Earl of Ancrum, and one in English to his 

 Countess. There are also complimentary verses 

 by J. Hooper, Christ. Drayton, Mr. Povey, Thos. 

 Beedome, and Ediu. Coleman. 



2. " Kalendarium Humanaj Vitae. The Kalendar 

 of Man's Life. Authore R. F., S.-13. 12ino. : Lon- 

 don, for W. Hope, 1638." 



With a Latin dedication to his patron the Earl of 

 Ancrum. The book contains verses upon the vari- 

 ous stages of man's life, under the heads of Spring, 

 Summer, Autumn, and Winter ; again subdivided 

 into moralisations upon the months, as correspond- 

 ing with the periods of life, as " August, or Man's 

 Youth," &c. This has also a variety of curious 

 cuts, and both have engraved emblematical titles, 

 the latter bearing on its face " G. Glover fecit." 



When book-rarities were in more request, these 

 were costly little volumes; and I shall be glad if 

 any of your correspondents can direct me where 

 to find any notice of Robert Fairlie, the author of 

 two of the most interesting of the emblematical 

 series. J. O. 



PHOTOGRAPHIC CORRESPONDENCE. 



[The following paper, wliich has been kindly com- 

 municated to us by Mr. Pollock at the request of 

 Dr. Diamond, describes a process which deserves the 

 especial attention of our photograpliic friends, for the 

 beauty and uniformity of its results.] 



MR. pollock's directions FOR OBTAINING POSITIVE 

 PHOTOGRAPHS UPON ALBUMEXISED PAPER. 



The paper should be carefully chosen, by hold- 

 ing up every sheet to the light, and only those 

 sheets which are homogeneous in appearance and 

 free from spots should be kept for use. 



The albumen should be obtained from new-laid 

 hens' eggs ; twenty-four is a convenient number to 

 u?e at a time : these will yield twenty-four ounces 

 of albumen, to which should be added six ounces 

 of distilled water (making thirty ounces in all) and 

 four per cent, of chloride of ammonium, viz. one 

 ounce and a quarter. 



The albumen water and chloride should be 

 whipped with a silver fork for several minutes, 

 and then put into a narrow tall jar, and allowed to 

 stand for not less than two days (forty-eight hours). 



In cool weather it v/ill keep well for eight days, 

 at the end of which time the upper half of the 

 albumen is to be poured off into a shallow vessel, 

 rather larger than the sheets of paper intended to 

 be albunienised. 



To put the Albumen on the Paper. — Take a sheet 

 by two opposite corners ; turn one up ; place the 

 sheet boldly on the albumen, the centre first com- 

 ing in contact with the albumen ; lower the corners 

 of the paper, gradually carefully excluding the air. 

 Let the sheet so placed remain four minutes : then 

 take it by the turned up corner, and rip it from the 

 albumen quickly, so as to carry up a quantity of 

 the albumen with it. Let it drain for a minute or 

 two, moving it so as not to allow the albumen to 

 run in streaks ; pin it to a piece of tape; and, when 

 dry, pass a very hot iron over the back. This 

 ends the albumenising process. 



To make the Paper sensitive. — Place the albu- 

 menised side downwards, for four minutes, on the 

 surface of a solution of nitrate of silver, of the 

 strength of ninety grains to the ounce of distilled 

 water ; pin it up by one corner to dry, and keep 

 it between pieces of blotting-paper. This must be 

 done by yellow light, or the light of a candle. 



T'o print from the Negative. — The simplest ap- 

 paratus to have is a number of pieces of plate-glass 

 a quarter of an inch thick, colourless, about twelve 

 inches by ten in size. 



The sensitive paper is to be placed on one of the 

 plates of glass, sensitive side upwards, and the 

 negative is to be placed firmly upon it, collodion 

 side downwards; and a second glass plate is then to 

 be placed on the negative, and the whole arrange- 

 ment exposed to the light. The time for exposure 

 is from three minutes to an hour. With a little 

 practice the negative can be lifted up, and the 

 positive viewed from time to time, without any risk 

 of displacement. 



The best rule is to print the lightest shade on 

 the positive very decidedly darker than it would 

 be wished that it should remain permanently. 



2'o fx the Positive. — On removing it Irom the 

 pressure frame, place it in a bath made as follows : 



Water 6 oz. 



Hyposulphite of soda - - - 1 oz. 



Nitrate of silver solution, 50 grs. 



to oz. - - - - - 15 minims. 



Iodide of silver, dissolved in a sa- 

 turated solution of hypo. - 10 minims. 



Chloride of gold - - - 2 grains. 



Chloride of silver (blackened by 



light) 5 grains. 



Acetic acid - - - - 2 drops. 



Mix these : let them stand some hours ; and 

 filter before use. If the chloride of silver is omitted, 

 the bath will do very well, but will very much im- 

 prove with age, as it will acquire chloride of silver 

 from the positives placed in it.
