To Catherine Darwin 5 July 
Rio de Janeiro. | HMS Beagle
My dear Catherine
I have only of an hour to write this—Sullivan1 will put it in his parcel, so that it will only cost common postage.— I have received your letter directed Monte Video & previous to it one from Caroline from Maer.— Tomorrow we sail for Mon: Video.— If the wind is not directly against us, we shall touch at Cape Frio, the celebrated scene of diving for the Thetis wreck.—2 They have fished up 900000 dollars.— If we are lucky enough (& it is very probable) to have a gale off St Catherines we shall run in there.— I expect to suffer terribly from sea-sickness—as we are certain to have bad weather.— After lying a short time at MV: we cruize to the South—but not I believe below Rio Negro— The geography of this country is as little known as interior of Africa.— I long to put my foot, where man has never trod before— And am most impatient to leave civilized ports:— We are all very anxious about reform; the last news brought intelligence that Lord Grey would perhaps re-continue in.— Would ask Erasmus to add to the books—Pennants quadrupeds3 (if not too late) in my bedroom.—& Humboldt tableaux de la nature.—4 You cannot imagine what a miser-like value is attached to books, when incapable of procuring them.—
We have been 3 months here: & most undoubtedly I well know the glories of a Brazilian forest.— Commonly I ride some few miles, put my horse & start by some track into the impenetrable—mass of vegetation.— Whilst seated on a tree, & eating my luncheon in the sublime solitude of the forest, the pleasure I experience is unspeakable.— The number of undescribed animals I have taken is very great—& some to Naturalists, I am sure, very interesting.— I attempt class after class of animals, so that before very long I shall have notion of all.— so that if I gain no other end I shall never want an object of employment & amusement for the rest of my life.— (Sullivan only gives me 5 minutes more—).— I am now writing in my own snug corner.—& am as comfortable as man can be.— I am only obeying orders in thus writing a short letter.— When on the deserts coasts of Patagonia.—you will be a long time before hearing from me.— My journal is going on better; but I find it inconvenient having sent the first part home on account of dates—
Give my very best love to my Father & all others. | Most affection | Chas Darwin.—
