To Charles Renard   28 May 1870

Sir,

I beg leave to thank you for your very courteous letter of May 20^th. in which you announced to me that the Imperial Society of Naturalists of Moscow has conferred on me the distinguished honour of electing me an Honorary Member.¹ This morning I received your Diploma²

I hope that you will express on my part to the Society how deeply I feel gratified by this honour. In accordance with your suggestion I have directed my publisher to forward to your Society the last edition of my Origin of Species and my Journal of researches during the Voyage of the Beagle³

With my sincere thanks | I have the honour to remain, | Sir, | Your most obedient Servant | Charles Darwin
