76 THE WOMBAT. 



Each manufacturer gives a formula for working each 

 paper, and no doubt, if the worker sticks close to the 

 instructions given, the results will, in most cases, prove 

 satisfactory. 



But it is to be noted that these various formulae are 

 regulated principally by the climate where the paper is 

 produced, and, as the bulk of it is made in the United Kingdom 

 and on the Continent, where the temperature all round is 

 much cooler than here, I am convinced, from practical 

 knowledge, that a slight alteration in the weights and 

 measures for toning, &c, is advantageous in these colonies. 

 Every photographer knows that heat accelerates the action of 

 his chemicals, hence the necessity for diluting, &c. 



My method of working Gelatino Paper is as follows : — 

 Firstly, wash the prints in many changes of cool water, as 

 much depends on the first washing for after results, then 

 immerse in the alum bath 



Alum, \ oz. • 

 Water, 24 ozs. 



for from 7 to 10 minutes, then wash in several changes of 

 water, and start toning operations with the following formula : 



Sulpho-Cyanide of Ammonium, 25 grains. 

 Chloride of Gold - 2 drams or grains. 



Water - - 22 ozs. 



I have found this bath to give evenness of tone, and not 

 too vigorous ; and when the desired tone is obtained, whicfe 

 takes from about 5 to 10 minutes, it will retain its brilliancy 

 and delicacy of tone in the fixing bath, where a vigorous bath 

 and quickly toned print will loose greatly, and possibly give 

 those indications known as double toning. 



Finished toning, the prints are again washed in at least 

 3 changes of water. 



Then the all important item of fixing comes next. One 

 of the great causes of yellow prints, and want of permanency 

 is due to insufficient fixing, and want of accuracy in weights- 

 and measures. To ensure success, it is absolutely necessary 

 that the fixing bath should be made up with the same exact- 

 ness as any other of the baths, and that the proper time and
