My dear Sir,

I greatly regret that I was absent when you called to-day—¹ I am usually here soon after 12 o’clock—but if it would suit you better I could come in at an earlier hour on any day that you named—

Now that the election for the Royal Society has taken place, I hope that I may be forgiven for expressing the great gratification I feel in the circumstance that you did me the great honour of placing your name on my certificate—² I assure you that the remembrance of this will always be a source of pleasure and an incentive to work to me

Believe me to remain | Yours very faithfully | John W Judd.

C. Darwin Esq.
