          from [Karl Friedrich Philipp von] Martius. I shall probably undertake
a synopsis Algaruum at a future time when my
exotic collection is more extended & with this
view use collection from all poarts of the world
as it is I possess the finest herbarium of Alga
in this country.

Before I dismiss the subject of my own 
concerns I am about to make you a proposal.
I knoow not whether you have got a copy
of Hooker & any Icones Filicum but for the moment
I suppose you have not. We only receive a
few plain copies each for all our labor & I 
have exchanged them with different correspondents
for books or plants. I have a copy left & would
have no objection to sent it you in exchange
for plants. But let me tell you how I am
situated. I commenced my herbarium upon
too small paper & unfortunately l glued down
many plants upon it. Two years ago I revolutionized
my collection - introduced a large fine
thick paper & have been at the trouble of
recollecting many British & European specimens.
So many of my American ones (mostly due to
your kindness) are in the same predicament that
I am anxious to procure others. If therefore
my proposal be agreeable to you let me know.
