Dear Sir,

I rcvd. your letter & parcels by Mr. Wright, &
am much obliged to you. I will forward the parcels
to Dr. Porter. I am surprised that he sends you bad
plants or badly preserved. It is said that his Herbarium
is a wonder of neatness & elegance, on which he
has employed years [crossed out: ?] upon a few plants. Direct a
box to Dr. Robbins for me, with a letter in it for
Hitchcock, so that I may know it is for him, &
I will get it & forward it to him. He is a particular
friend of mine. Tho' I can not often send to him, yet
I can get it to him.

That Gray Augite, Tremolite, Zoisite, is Scapolite, it seems.
It is not Augite it never could be Zoisite, tho' Prof. Hall
calls it so, & I never did &, I doubt very much about
its being Scapolite, for one. It may be but it melts often
exactly like Tremolite, enamel porous, etc.

I want you to look carefull at those impressions
in that Fetid Lime. If they are not shells, what are they?

That "curious Talc," certainly exfoliates wonderfully, & no
description tells so much. Indeed that amount of Talc [needs?]
amendment.

That Cornelian, called Pitch by Nuttall, did not
occur in the Serpentine. I never saw anything like it in
Serpentine. it was not near the Serpentine rocks - but a
solid rock in a stone wall [never?] [even?] [smelt?] of Serpentine,
& when you get Magnesia out of it, I shall like to see it.

You are greatly mistaken about that Pinite it is
Pinite, altered by action of air & water at least, it is not
