D^r Sir

I have seen in various publications some slight notices of your having discovered by means of spectrum analysis a new metal called Thallium thus verifying a prophecy I made in 1826 (Brewsters Philosophical Journal vol. V p. 81) As I am not in the way of seeing the scientific journals here, I should be glad if you would inform me where a more detailed account of your discovery has been published? and if you have any separate copies printed of any paper I should be very glad of one. I suppose the name Thallium is derived from [Greek text] on account of the green ray.

I remain Yours very Truly
H. F. Talbot
