Miscellanies, 167 



anniversary 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 Trumbull, Dwight, Humphreys and 

 Barlow, the first of whom only survives ; clarum et venerabile nomen.^ 



26. Encyclopedia Americana. — The fifth volume 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- 

 ism, Geology, Granite, Feldspar, Fluor and Garnet. The minera- 

 logical articles, in particular, are drawn up with precision and skill, 

 are sufficiently full, for such a work, and are brought down to the 

 present time. A great amount and variety of useful knowledge are 

 compressed in this Encyclopedia, which deserves and cannot fail to 

 have an extensiv^e 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- 

 retted 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 

 already attained great excellence, as appears from the rich display of 

 esculent, as well as ornamental productions, made at the horticultu- 

 ral exhibitions.!

 and legal ornament of his country and of his age. 



I That of Philadelphia, in June, 1830, which we saw, was very splendid.
