_Towgood's Paper._--A. B. (Vol. ix., p. 83.) can purchase Towgood's
paper of Mr. Sandford, who frequently advertises in "N. & Q." With
regard to his other Query, I think there can be no doubt of his being at
liberty to publish a photographic _copy_ of a portrait, Mr. Fox Talbot
having reserved only the right to paper copies of a _photographic_
portrait. Collodion portraits are _not_ patent, but the _paper_ proofs
from collodion negatives are.
