great interest which he still felt in the advancement and dif- 
fusion of scientific knowledge in this country, was manifested 
by his continued and munificent benefactions to the Academy 
of Natural Sciences at Philadelphia.’ It was his desire also 
that some competent person, at his expense, should collect 
additional information respecting the forest trees of North 
America, and prepare a new and augmented edition of 
Michaux’s Sylva. Although this generous plan was not car- 
ried into execution in Mr. Maclure’s lifetime, we understand 
that he left testamentary instructions for its accomplishment, 
or at least for the reprint of Michaux’s original work. 
Mr. Maclure’s munificent intentions are — fulfilled, shall 
we say? by the edition now before us, printed at New Har- 
mony, Indiana, upon wretched, flimsy, whity-brown paper, of 
texture scarcely firm enough to receive the impression of the 
worn-out type, which seems to have done long service in the 
columns of some country newspaper. The engravings, to do 
the work full justice, are very good, at least in the colored 
copies ; being impressions from the original plates imported 
by Mr. Maclure, and colored after the French edition. The 
subscription price was high enough to pay for the best typog- 
raphy and paper; and so popular a work would surely have 
found a ready sale at any reasonable price, as the Paris edi- © 
tion had been long out of print. We are bound to suppose 
that the testamentary instructions of the late Mr. Maclure 
have been literally fulfilled. How far his generous inten- 
tions have been answered, or to what extent defeated, by the 
wretched character of the reprint, are questions which we 
shall not attempt to answer, except by stating that, far from 
having obtained the wide circulation which Mr. Maclure 
desired, these volumes have entirely disappeared from the 
shelves of our booksellers, where, so far as we can learn,

the choicest works in natural history, antiquities, the fine arts, voyages 
and travels, ete., and many smaller contributions to this flourishing insti- 
tution, of which he was president for more than twenty years, Mr. Ma- 
clure presented to it, in the latter part of his life, the sum of twenty 
thousand dollars. See Dr. Morton’s “ Memoir of William Maclure,” 
Philadelphia, 1841.
