23, Alfred S^t Islington,
Nov. 18, 1858.

D^r Sir,

I am in some doubt as to whether I understand you or not. My portraits plates are all negative collodion on glass, and from these I get the prints which I publish. The prints of course are positives, in one sense, but I am not certain but that you require positives on glass.

If you want sharp prints only I will send you some at once, but you will perhaps apprise me first if these will be of any service, or whether by copying or any other process they may be made available for your purpose

D^r Sir Yours very sincerely
Herbert Fry

H. Fox Talbot Esquire
