I have now to inform you, with reference to our previous correspondence, that owing to our limited space and the large number of Fellows expected at the meeting for discussion on Colour Photography, the President and Council do not see their way to depart on the present occasion from the standing regulation that visitors can only be admitted on the introduction of a Fellow, each Fellow having the privilege of admitting two.
I am, yours faithfully,
Asst. Sec. R.S. [Assistant Secretary, Royal Society]'.
