My dear Sir
Your facts are very important and when such like have been multiplied & closely examined we may be able to form some idea of the manner in which the poisonous particles are differentiated at present we can only suppose a manner[.] Nevertheless the facts if confirmed are equally important for if the presence of a body causes injury it is not necessary to wait until we know how it does so before we dismiss it[.]
Ever My dear Sir | Yours Very Truly | M. Faraday
F.O. Ward Esq | &c &c &c
Endorsement: Reply to note about the “Emerald green“ i.e the arsenio-acetate of copper, now used as a pigment - certainly with injury to workmen employing it - probably with danger to the occupants of rooms decorated with it.
