10. Fossib Shells of the Tertiary Formations of the United States, 
by T. A. Conrap. No. 2. J. Dobson, Philadelphia—We have 
/much pleasure in announcing the second number of this. valuable 
work, with eight lithographic plates, illustrating seventeen species of 
our tertiary fossils. It is really cheering to observe that this depart- 
ment of American geology, is now in a fair way to be fully elucida- 
ted; and we must confess our surprise that such interesting facts, such 
multiplied materials for geological reseach, should not sooner have 
called forth the talent and attention they so justly merit. Mr. Con- 
rad’s second number contains five species of Crassatella, one of Tur- 
binella, four of Ancillaria, four of Ostrea, a Macta, and a Pholado- 
mya. These fossils are taken indiscriminately from the upper and 
middle tertiary deposits, and from localities widely distant, New Jer- 
sey, Virginia, the Carolinas, Alabama, &c. Mr. Conrad is now ona 
tour in the southern states, collecting materials for the continuation 
of his work; from this cause the third number may be delayed until 
April or even until May. Those persons who feel interested in the 
geology of our country, may look forward with pleasing anticipations

‘11. Anthracite in Wrentham, Mass.—Specimens of this mineral 
have been forwarded to us by Mr. S. Day, in a letter dated Provi- 
dence, R. I. Oct. 11. It is stated to be newly discovered—that the 
boring-has been carried to eighty feet and the excavation or shaft, to 
sixty ; that the coal lies in strata of different depths, interspersed with 
slate, and that it is proposed, should the prospect continue fair, to pe- 
tition the legislature for a charter of incorporation, and in the spring 
to push their enterprise with vigor. = 
The coal appears like the European anthracite, and resembles 
that of Rhode Island more than that of Pennsylvania. The latter 
State possesses such vast resources in this mineral, and of such admi- 
rable quality and easy acquisition, that prudent men will look well to 
every undertaking, which must depend, in a degree, upon successful 
competition. * 
12. Comparison of weights and measures of length and capacity, 
reported to the Senate of the United States by the Treasury Depart- 
ment in 1832, and made by Ferd. Rod. Hassler, M.A.P.S., &c. (Doc. 
No. 299.) Washington, 1832.—On the 29th of May, 1830, the 
Senate passed a resolution requiring a comparison of the weights and 
measures used in the several custom houses in the United States,
