14. American Botanical Register—The nature and object of this 
work, were announced at p. 160, of our last volume, to which ne- 
tice, we refer our readers. 
We have now to state, that in accordance with the plan, No. 1 of 
the work has appeared, and the numerous colored engravings beau- 
tifully executed, have fully redeemed the engagements of the editors 
on thathead. We trust that the work will prove useful to the ad- 
vancement of botanical knowledge. pl: 
15. Encyclopedia Americana.—The seventh volume of this val-

Navy Yard at Gosport, for the very useful tables named above 5 
from their source we cannot doubt of their accuracy, and every thing 
of this kind is particularly. interesting, in a country which is eminent-

V7. Science in the West.—Useful knowledge is advancing in these 
favored regions with the general progress of society. We have 
already mentioned the Detroit Lyceum, and, in a large, handsome, 
and well arranged newspaper,—The Detroit Journal and Michigan 
Advertiser, —we observe a discourse or lecture, pronounced in May 
last before that institution, by Mr. Schoolcraft; it is interesting and 
‘asttuctive, and replete with the personal knowledge, acquired by 
that gentleman in his extensive travels, in the interior of this conti-
