in the manner of De Candolles davis analytica in the H. Francaise.
In Mineralogy I have not heard of anything. Brewsters' discoveries 
you will doubtless have seen or heard of, respecting
the connection between the primitive forms of chryotals & the
number of their axes of double refraction. He now in describing
a mineral gives the optical as well as its other charactors.
tryed by this test Haug's arrangement is in many respects
false & the one lately proposed by Professor Mohs most
correct but it is singular to see how correct both have
been in most cases, considering the Wernerian Soc. memories (to
which I have just completed the index) you will find 2 papers
on this subject by Brewster. With regard to Zoology—this

work on [insert: the] Birds of this country ever published in Great Britain, it
is by a gentlemen of Fortune (W. Selby of Fruzel house Northumberland)

L5-5-0 colored. 2 fasc: appear annually tell DeKey it is dog cheap &

is little chance of the Phil. Journal being continued under their joint
names. Brewster will take it to himself & Jameson I suspect is
thinking of a Journal of Nat. hist [Natural history] to be published quarterly. it will
succeed if he does it properly—at the beginning of next year one of two
other gentlemen & myself think of editing a periodical work on nat. hist. [natural history] not a journal, but only plates & descriptions of new or rare
objects—but tho we have consulted the Engravers & it is not
