Dear Sir,

Your valuable boxes came safely & the package
of plants also. And my first object is to return my thanks
for them. Many were new to me, & [valuable?] about them
I want to ask a few questions.

["Sphinc".?] Is it Lilico-calc. oxyd of [Litanum?] of Cleaveland?
["Cevine?] on Actynote" [Actinote?] - what is it in Cleaveland? _ or is it new?
"Albite", what is it, & also Loboite, & [Rothossit?]?
"Ziolithe [parineaux?]", is it Mealy Z. in Cleaveland?
"Spinelli,"_ is it those smoky or bluish smoky crystals - I had
no idea, it had such an appearance.

"Gahnite"_ is the same in Cleveland? "Fahlunite" is a syn
onym of Gahnite, but may be different _ but the
Fahlunite is the Gahnite of Cleavland, & seems to me
to be in Talc, passing into [Steatite?] _ [?] it is not
Chlonite Slate.

That mass from Schoolcraft. The white & green is [Prchn
ite?], & not quartz - boils vehemently before blowpipe, cuts 
glass, etc. & must be P. I have not had time to examine
the brown part as I wish, but it looks like Petrosilex, & I
suspect it to be so it melts into a black or [?]
glass, which Pet. does sometimes, & with difficulty is
hard, or so on & I suspect you will make it out. To
be sure, I have spent only a minute on it & would not
write this, if I was like to get time to [task?] it before this
letter must go. The Ore from [Con?]. I have not tried it
all. I am excessively hurried, while our Prst., Dr. Griffin
is coming on. But as Mr. Wright is going to N. Y., I must
write & send to you. I send only 3 or 4 minerals, for I have
lately rcd. nothing new from this quarter. Such as I have
sent, I hope you will like, tho' they are small - for they
are good.

I send also some plants - among which are the
new ones found here this season, & also some of  
those more rare, which you have often asked for, &
some of which I have sent before, & some I have not
before sent, because I could not find them. I have
sent Aspidium obtusum? but it can't be it but
what is it? That is the point. I have sent A. dila
tatum, as you call it I believe. That Galium  what
is it? Fruit, perfectly glabrous. One of the specimens I send,
has some marks on it it is not pubescent or villose.

I am greatly hurried & have time only to do a little at
