My dear Sir

I am sorry that I have caused you any inconvenience by having Krusentern’s atlas2 in my possession.—

Sulphur Isld is laid down in the chart of the Loo Choo Archipelago in

27o 56’ N

128 . 27’ E. of Greenwich. (as near as I can take the degrees off with compasses) There is, also, in the general chart of the northern Pacific a Sulphur Rock (Position Doubtful) in 31o 28’ N. and 142o 18’ E. Greenwich—

There is (in the plan of Japan and adjacent islands) a “I. du Volcan”, in 30o 44’ N. 130o 24’ E of Greenwich as near as I can take them with compasses which would give nearly the same longitude, when corrected to Paris obser; as that you mention.— I have an indistinct recollection that this isld was formerly called Sulphur isld

I presume you will find a full account of Krusentern’s authority for these positions in his memoir3 of 1827—which I have not here, but is at the Geograph. Soc.

Believe me | very truly yours | Chas. Darwin

P.S.| Of course if you want Krusentern, I will return it immediately.—

I believe there is a copy at the Admiralty should you want to see it, before I can return that belonging to the Soc.
