In reply to your letter of the 8th inst. [instant], with reference to the figures illustrating your paper on Constant Standard Silver Trial Plates, I have to say that the five diagrams will be reproduced in the Proofs which are issued for the convenience of Fellows at the meeting, and will therefore be easily accessible for reference at the meeting.
I am, yours faithfully,
R [Robert] Harrison
Asst. Sec. R.S. [Assistant Secretary, Royal Society]'.
