80 Paper Process in Photography. [no. 1, new series, 



that the Sun has done what he was unable to effect. For the glass 

 plate of the printing frame becomes so hot as to transfer the wax 

 from the negative to the positive, through the coagulated albumen. 



Having said all that appears to be necessary on the subject of 

 un waxed paper, I will add what may be necessary to enable the 

 novice to use waxed paper. He will find at the outset that it is 

 much more difficult to immerse waxed papers in the iodizing solu- 

 tion, the difficulty is lessened when there is a good depth of solu- 

 tion, I have also found that the papers are more easily immersed in 

 a solution made with whey than in one prepared with water. In 

 exciting waxed papers, float twice the time directed for unwaxed 

 2:>apers. They will require about five thirds the exposure, and ge- 

 nerally, the development, fixing, and washing of waxed papers will 

 require a longer time. With these exceptions the manipulation is 

 the same as with plain papers. 



In conclusion I have only to add, that the method of manipulat- 

 ing is that followed by Captain Tripe and Dr. Neill, which will 

 recommend it more to your notice than anything I can say in its 

 favour. They do not soak their papers so long in the iodizing so- 

 lution as I recommend. It was an experiment with me, and the 

 result having proved satisfactory, I of course direct you to do that 

 which has succeeded in my hands. But I am not certain that such 

 lengthened immersions are necessary, though I am quite satisfied 

 they are not injurious. The iodizing compound contains nothing 

 new to Photography, but the proportions are different from any 

 published formula, I believe. How much of its greater rapidity 

 of action is due to that (or perhaps the longer immersion in the 

 iodizing bath,) I am not prepared to offer an opinion, because 

 neither my leisure nor circumstances permit me to enter into numer- 

 ous experiments. But I know it is considerably quicker than any 

 modification of the waxed-paper process that I have tried, it is 

 as quick as the Calotype, and I think is deserving of a more ex- 

 tended trial by Indian Photographers than an. Individual has the 

 power to give it. It is doubtless capable of improvement, and the 

 probability of this will increase with the number of hands that can 

 be induced to give it a trial.
