My dear Sir/

I have been going on with experiments in the Callotype ^<1> & have had some very good results as to depth of Colour. I never get the paper so yellow as that which you have been good enough to send me I will try it directly. I hardly think y [sic] Iodite [sic] of Potassium is strong enough –

believe me yours very sincerely
L. L. Boscawen Ibbetson.
