Wash thoroughly and tone through to the glass with the before 

 mentioned gold solution and wash and place the plate in water 

 acidified with sulphuric acid. This will loosen the film. When 

 free from the glass, raise ii up 3 holding it in place on the plan- with 

 the thumbs and rinse under the tap. 



Place an ordinary glass now in a tray with water, turn the picture 

 down upon this and allow it to floal off the plate glass. 



Center the film now on the glass in the water, raise the glass up, 

 holding the film in position with the thumbs, now take a piece oi thin 

 paper, immerse it in the water and lay it down upon the film. 



We will suppose that yon have in the meantime coated the block 

 with flake white with just enough Heinrich's gelatine to make- it 

 adhere to the block. This will he enough to make the picture also 

 adhere. 



Raise the paper up now with the film upon it and lower from one 

 side upon the block in such a way as to exclude air bubbles. 



Tut a piece of moist blotting paper upon it and place in a letter 

 press and put the pressure on for about two minutes, then remove 

 it. strip the paper off in such a way as not to lift up the film and 

 remove the surplus film from the edges and turn the block face down 

 in the mixture of ether and alcohol; this will remove the pyroxylin 

 and leave the image on the wood. 



This process also makes an exquisite collodion transfer on paper.
