Apr 28 / 56

D^r Sir

I entertain a strong opinion that no person has a right without your licence to use Gelatine mixed with Bichromate of Potash applied to a surface in the dark and then to take a picture by the Camera or otherwise by the aid of light and then to wash off by water the parts not acted on by light.

Yours v^y truly

William Carpmael
