of magnesium however I would [?] with pleasure. I forgot to mention
that altho' I prefer cryptogamia I am very partial to all the graminoid 
cyperaceaeypera etc. many of cour carices were acquisitions to me. It is a
genus I am very fond of. No orchideous plants can come amiss. America
possesses some very fine ones. It is very uncertain when this
packet will go but I shall send it by the first opportunity.

Remember me very kindly to [DeKay?] who I believe has an unaccountable
stiffness in his fingers which probably saves him much ink & paper. 
I thank him for his postscript however & for the introduction in which he
very wittily says began at the end. He says he will write me a whole letter
soon. I do not let him accuse me of a bull if I say his whole is likely to
be but a part.

I remain [?]
yrs very truly
