new species.—Hooker has also commenced a very useful work 
called the Botanical Miscellany [10]. There is an excellent work 
entitled The Magazine of Nat!. History [50] edited by Loudon, in 
London—It comes out every two or three months, is quite cheap & 
contains much botany.—You probably have seen the enormous, 
but most excellent book by the same editor, entitled ‘“‘ Encyclo- 
pedia of plants” [49]—comprising an account of all plants culti- 
vated in Britain, together with the natural species—a single vol. 
of nearly 1300 pages, very fine print, large 8 vo.—with 1,000 cuts in 
excellent style, of about 10,000 species. The work was prepared 
by Lindley, who has filled it with interesting matter—The price 
is $25 or $26. Lindley is preparing an introductory work on the 
. Natural Families of plants [45]. He has lately pub. a Synopsis 
of the British Flora [47],’ containing description of the phenog. 
plants and filices of Gt. Britain, in nat. orders.—Hooker has 
ready a British phenog. Flora according to the Lin. Syst. [32]. 
The plants &c. sent home by Dr. Gates are worth but little— 
they comprise a few things which he collected very early last 
spring near N. Orleans, and some given to him by a collector who 
picked them up in the same district. Le Conte and I divided them 
by lot among our subscribers. Almost the only interesting articles 
among them are a new (or perhaps Mexican) species of Campanula, 
allied to C. simplex—and some good specimens of what I take to be 
your Thelephora coccinea—Syn. fung. car. inf. I find it to yield 
a beautiful scarlet to alcohol or water, which may be used as a 
dye, that resists both acids and alkalies. Dr. G: lost the whole 
of last season by severe and long protracted sickness, but he 
will remain another seasonein the country, and believing himself 
to be now acclimated, he hopes to be successful in making large 
and valuable collections before next autumn.— 
Yours truly, 
Joun TORREY.
