Mr Maskelyne
Wedny night
Dr Sir
As my witnesses may possibly be detained some hours on Monday, 1 I have thought it desirable to engage a room for their accommodation at the Guildhall Coffeehouse corner of Gresham St and King St, close to the Guildhall. 2 If you please to enter there enquire for Mr Talbot’s room –
We have made some pictures by the Calotype process, on compound sheets of paper viz. half iodised paper and half paper coated with iodised Collodion
This shows to everybody that the latter paper is a substitute for the former
Yours Truly
H. F. Talbot
