In my process The pos & neg images are not seen as you imagine at oppos. sides of the plate but both on the same side, in changing from 1 kind to the other altntly accg to ye directn of ye light – in ye manner of ye images on a Dtype plate
They have ^indeed a gt deal resblce to Dtype picts so that sometimes it especlly when a black cloth is held behind them, but they have not ye slightest resemblce to ye paper photogrhs to wch y allude, wch bear a posve image on 1 side & a negve on ye other

I thank your for your Courtesy in sending me a copy of your letter to the Athenæum. <1> I shall request the Editor if he inserts your Letter, to insert also my a reply from me
I am happy to inform you that there is not the least resemblance between my Amphitype process and that described by you in 1845, except that I employ the iodide of iron (not the syrup of it, which does not answer) –
In my process the positive and negative images are not seen as you imagine at opposite sides of the plate but both on the same side, in changing from one kind to the other alternately according to the direction of the light – in the manner of the images on a Daguerreotype plate They have indeed a great deal resemblance to Daguerreotype pictures so that sometimes it especially when a black cloth is held behind them, but they have not the slightest resemblance to the paper photographs to which you allude, which bear a positive image on one side and a negative on the other
