jan. — mar. 1857.] Photographic Printing Process. 169 



ends lodged in squared hooks at intervals of 10 inches on the sticks 

 — the rods fitting the hooks — I have on a space of wall 12 feet long 

 dried 143 papers almost daily for months and find it most convenient. 



In conclusion I would mention what seem to me to be the ad- 

 vantages of the Process I have described. 



First. — The saving of time in not overprinting as required by 

 the old Hypo, processes. 



Second.- — The agreeable tone of the picture — its firmness and 

 the preservation of its half tones. 



Third.-— The comparative certainty of its working. 



Fourth and most important. — The permanence. Prints sul- 

 phuretted have been proved to be not so safe from fading as 

 Prints coloured by Gold. In this Process the toning is by 

 Gold only — and with subsequent care in washing this seems 

 to be as safe as Photographic Printing can be. 



I must not close without reminding you that neaily all of this is 

 given in Photographic works — and that I am merely bringing the 

 subject to your notice that you may benefit by it as I have done. 



The subjoined Table of " Formulae for preparing Albumenized 

 Paper," was communicated by Captain J. D. Scott, of the Madras 

 Artillery. 



" Similar Tables" he observes " might be drawn up for the 

 " Fixing and Toning Baths" &c. &c. 



" In England 1 Egg gives an ounce of Albumen, but in this 

 country, when the Eggs are very much smaller, I find that 24 

 Eggs give about 16 ounces of Albumen, i. e. 1 J Eggs are required 

 to give 1 ounce."
