To William Lonsdale   14 April [1841]

My dear Lonsdale

I send you the accompanying paper for the disposal of the Society.—¹ It is not so long as it looks, from the largeness of copyist’s hand & width of lines.—

I have sent two or three foot notes on separate pages.—

I believe you look over Papers before they are read, so will be able to decide what maps are required to illustrate it.— I should think a rough outline in large of Eastern parts of Tierra del Fuego & Chiloe ?? would be advantageous— I send you two maps (for no old ones are accurate) which will you please take care of, when you have looked over my paper— I hope to improve the English, should it be ordered to be printed, & perhaps curtail it, but I thought I would give my facts in detail, as no boulders have been described in any part of S. Hemisphere.—

It has been the work of such hours, as I have been well enough during two last months!— Will you be so kind as to write me a line whenever it is to be read, as although I shall not be able to attend myself, I will get my cousin to be present to tell me whether there is any speaking on the subject.—

My dear Lonsdale | Most truly Your’s | C. Darwin Wednesday
