|Description||'Dear Dr Sanderson,|
There is no way of adding to an old certificate: but, by a statute quite recently passed, you can, if you please, take out a supplementary certificate which, however, has to be signed by six Fellows, in addition to the signatures already attached to the original certificate. I note what you say about Prof. Ewert's paper and the two certificates of Professors Ewart and Gotch have been re-suspended.
I am, yours truly,
Asst Sec RS [Assistant Secretary, Royal Society]'.
