H. Fox Talbot Esq.
Dear Sir
I have a large transparency on glass and a small one on opal ready for you, and will send them off per rail to day
They would have been done sooner but we found rather a difficulty with the opal glass as it is a new substance to us – I hope they may suit your purpose of experiment & should like much to have a print when done
Wishing you every success in your process
I am
Dear Sir
Yours Truly
John Moffat
