From Cuthbert Collingwood   30 March 1868

Dear Sir

Engaged as you must be in the great work upon which you have entered, I fancy you will find little time for the perusal of the book which I have had the pleasure of sending you.¹ Still as one who has endeavoured to a certain extent to follow in your footsteps, I felt I could not do less than send you my journal of Researches—begging you however to kindly remember that I had but 18 months experience of travel.²

I very much regret that owing to a mistake the book should arrive a week or so after date & beg you to be kind enough to excuse it—

I am dear Sir | very faithfully yours | Cuthbert Collingwood

Charles Darwin Esq F.R.S.
