apniversary is thus ably commemorated in a place which, within the 
memory of persons still living, was regarded as scarcely an “ out- 
post of civilization,” is an object of peculiar interest ; and the state of 
useful arts there is sufficiently indicated by the beautiful paper and 
typography of this discourse. Detroit, with its dawning literature, 
has, however, the honor of affording a retreat to a venerable and ac- 
complished scholar, jurist and poet; the only survivor of a brilliant 
circle, who adorned the early literature of their country, which will 
never forget the names of Trumsuti, Dwicut, Humenreys and 
Bartow, the first of whom only survives; clarumet venerabile nomen.* 
26. Encyclopedia Americana.—The fifth yolume of this work is 
just published. Our impression, derived from an examination of a 
few articles in this volume, relating to Natural History, Chemistry, 
General Physics, &c., is equally favorable as that expressed in rela- 
tion to the first volume. As specimens in these departments, in the 
Present volume, we would refer our readers to the articles Galvan- 
‘sm, Geology, Granite, Feldspar, Fluor and Garuet. The minera- 
logical articles, in particular, are drawn up with precision and skill, 
ate sufficiently full, for such a work, and are brought down to the 
Present time. A great amount and variety of useful knowledge are 
®ompressed in this Encyclopedia, which deserves and cannot fail to 
have an extensive circulation. 
_ 27. Crystallized Carbon.—Dr. C. C. C. Cohen, of New York, 
in company with Mr. J. Boston, while passing vapor of alcohol 
through an ignited iron tube, for the purpose of forming pure carbu- 
feted hydrogen gas, obtained a large deposit of charcoal, among 
Which “ were several specimens of perfectly bright needles of crys- 
tallized carbon,” resembling that obtained while passing carburetted 
hydrogen gas over ignited iron, for the purpose of converting it into 
Steel, and described in Henry’s Chem. 11th ed. Art. Carbon.— 
(Letter to the editor, March 22, 1831.) 
28. Horticulture.—This elegant and useful art is constantly re- 
ceiving increased attention in this country, and in many places has 
eady attained great excellence, as appears from the rich display of 
*sculent, as well as ornamental productions, made at the horticultu- 
ral exhibitions. + 
* Which Mr. Walsh has recently applied, with equal felicity, to another literary 
and legal ornament of his country and of his age. 
' That of Philadelphia, in June, 1830, which we saw, was very splendid.
