180 : Miscellanies. 
Although it is intended to elucidate the Molluscous animals, of 
all North America, yet it is proposed to introduce those of the Uni- 
ted States chiefly, into the first part of the work, so that those sub- 
scribers who may wish to limit their inquiries or expenditures to the 
shells of this union may be accommodated. : 
We have no doubt the able author will redeem his pledges, if sus- 
tained by an adequate subscription on the part of the public, and we 
sincerely hope that a scientific work, so likely to prove creditable to 
the country, will not be suffered to languish or die, for want of the 
required assistance. 
We regret that Mr. Say has not thought it better to publish the 
species of each genus together. When the work shall be finished, it 
will not present any systematic order, unless the whole be taken to 
pieces and rearranged. - For the sake of making the rarer and more 
doubtful species known, we should have preferred that those should 
have been described in the early numbers, and such species as Oliva 
literata, Paludina decisa, &c. well known, and in most of our cabi- 
nets, left until towards the conclusion of the work. The plates at 
executed with great accuracy, and we must not withhold our praise 
from the fair artist who has so. happily delineated the illustrations 
Were we disposed to censure any partof the work, it would fall oa 
the compositor and pressman, who might be a little more careful, and 
free the work from inaccuracies and blemishes, which are not credit 
able to the present state of the American press. 
3. Prof. Griscom’s address to the Newark Mechanies Associt- 
tion.—This discourse, delivered in January, 1831, is replete with 
sound sense, with exact and valuable knowledge, and with the most 
important moral and practical views. It is lucid and attractive; 
and must have given much satisfaction to the very respectable wei 
ciation to which it was delivered. ‘That association, situated m # 
flourishing and beautiful town, appears from the report, appended 
the published discourse, to be in a prosperous and eflicient conditio? 
and, we trust, will prove eminently beneficial to the members of the 
institution, and to the spread of useful knowledge in our countly: 
4. Gen. Cass’s address before the Alumni of Hamilton Collegs 
August, 1830.—A chaste, eloquent and beautiful production; N° 
in valuable thoughts and facts, and in sound views of classi? i 
learning. Gen. Cass is a fine example of the union. of Jiteratut? . 
with active habits both in the field and in civil life.
