THE LONGEVITY OF TREES. 
Tue “ Histoire des Arbres Forestitres de ? Amérique Sep- 
tentrionale”’ of the younger Michaux is chiefly known in 
this country through the English translation made by Mr. 
Hillhouse, under the superintendence of the author, who 
added some new plates, and information not contained in the 
French edition. It was published in Paris in the year 1819. 
We have no intention of formally reviewing, at this late day, 
a work of such long-established reputation as the Sylva of 
Michaux. It has been the standard treatise upon the subject 
ever since its publication; and it well deserves the rank it 
holds. We wish rather to offer our grateful acknowledg- 
ments to the memory of the late Mr. William Maclure for 
his liberal endeavors to render this important and quite ex- 
pensive work more generally accessible in the country, the 
noble forests of which it is designed to illustrate. In fur- 
‘therance of this object, Mr. Maclure, if we are rightly in- 
formed, purchased in Paris the copies which remained unsold 
the year after its publication, and sold them in the United 
States at a very reduced price. With liberal forethought, 
he bought also the original copperplates of this book, and of 
several other expensive works of science and art; intending 
to have them reprinted in this country in a cheaper form, so 
as to insure them a wider circulation.2__ During the last twelve 
years of his life, or from the time of the total failure of the 
‘ oreat social experiment” made at New Harmony, Indiana, by 
the celebrated Robert Owen and himself, down to his decease 
in 1840, Mr. Maclure resided in the city of Mexico. The

Naturelle des Oiseaux de l’Amérique Septentrionale ” ; and Audebert’s 
“ Histoire Naturelle des Oiseaux,” etc.
