I have to acknowledge receipt of your letter of the 13th November and the accompanying manuscript entitled "Postulat d'Euclide". It is a strict rule that all papers intended for reading before the Royal Society must come "communicated" by a Fellow of the Society. Your paper does not comply with that regulation, and I have, therefore, to return it to you herewith (by registered book post).
I am, yours faithfully,
Asst. Sec. R.S. [Assistant Secretary, Royal Society]'.
