My dear Sir

I received Henslow’s letter last night too late to forward it to you by the post, a circumstance which I do not regret, as it has given me an opportunity of seeing Captain Beaufort at the admiralty (the Hydrographer) & of stating to him the offer which I have to make to you: he entirely approves of it & you may consider the situation as at your absolute disposal: I trust that you will accept it as it is an opportunity which should not be lost & I look forward with great interest to the benefit which our collections of natural history may receive from your labours

The circumstances are these

Captain Fitzroy (a nephew of the Duke of Graftons) sails at the end of September in a ship to survey in the first instance the S. Coast of Terra del Fuego, afterwards to visit the South Sea Islands & to return by the Indian Archipelago to England: The expedition is entirely for scientific purposes & the ship will generally wait your leisure for researches in natural history &c: Captain Fitzroy is a public spirited & zealous officer, of delightful manners & greatly beloved by all his brother officers: he went with Captain Beechey¹ & spent 1500£ in bringing over & educating at his own charge 3 natives of Patagonia:² he engages at his own expense an artist at 200 a year to go with him: you may be sure therefore of having a very pleasant companion, who will enter heartily into all your views

The ship sails about the end of September & you must lose no time in making known your acceptance to Captain Beaufort, Admiralty hyd^r I have had a good deal of correspondence about this matter, who³ feels in common with myself the greatest anxiety that you should go. I hope that no other arrangements are likely to interfere with it

Captain will give you the rendezvous & all requisite information: I should recommend you to come up to London, in order to see him & to complete your arrangements I shall leave London on Monday: perhaps you will have the goodness to write to me at Denton, Darlington, to say that you will go

The Admiralty are not disposed to give a salary, though they will furnish you with an official appointment⁴ & every accomodation: if a salary should be required however I am inclined to think that it would be granted

Believe me | My dear Sir | Very truly yours | Geo Peacock

If you are with Sedgwick I hope you will give my kind regards to him
