Dear Sir,

I received some time ago from M^r. Scott in Calcutta a large parcel of worm-castings from S. India.¹ These are of extreme interest to me.

M^r. Scott informs me that you were so kind as to collect these specimens, & that you had some notes respecting them. I have heard with much regret that you have come home on account of your health, & therefore I scruple to trouble you. But if you are well enough to send me these notes, I shd feel grateful. Otherwise, I beg that you will not acknowledge this note, & in any case, accept my cordial thanks for your kindness.

Hoping that your health may improve, I remain | Dear Sir | yours faithfully | Ch. Darwin
