Observatory. Clifton Bristol
Decem 21st 1842
having been for some time as an Amateur engaged in photographic pursuits I shall feel obliged if you will inform me upon what terms I may be allowed to practice the Calotype or introduce it to the Bristol public.<1> there is in the City the Daguerreotype by a license of the patentee<2> already so that any profit I fear for –
I Remain Sir Your most oblged St
To H. F. Talbot Esqre
W. H F. Talbot Esqre
1. West had been selling prepared photogenic drawing paper in Bristol - that process was not patented.
2. Although Daguerre's invention was purchased by the French government and was supposedly free to the world, his agents attempted to patent it in England.
