5. The Plough, the Loom and the Anvil; T. S. Sxuvner, Editor.— 
This monthly periodical of practical and economical science, comes to 
mon 
United States, and is by H. C. Carey. It surveys the products of the 
country in these different departments with much valuable statistical 
detail, stating in tables the productions for successive years, of iron, coal, 
lead, woollens, &c., &c., and also illustrating the same by means of 
diagrams ; and exhibiting a wide comprehension of the interests of the 
Country in its various economical departments. Cotton Mills by Cotton 
Growers, Irish Peat, Charcoal and Sanitary Reform, are the subjects 
of other papers; and besides these, there are many shorter articles of - 
Practical value to the farmer and mechanic.

partments of Reptiles and Birds. The sketches are forcible and char- 
acteristic, illustrating the habits and haunts of the animals as well as 
orms. 
7. Foster’s Geological Chart.—It has been represented to us that 
the Geological Chart noticed in our last number had not been finished, 
—although the copy received was varnished and mounted in the usual 
finished style ; and that therefore it was not a fair subject for criticism. 
A revise copy, as now ready for publication, having the signatures of 
Professors E. Emmons and V as been shown us by the 
author. It has undergone important changes, though not all we should 
Wish to see made. Figures of American fossils have been substituted 
to a considerable extent for foreign ; misplaced fossils in the formations 
and the succession of rocks have been set right, and the names of the 
New York series of Rocks have been introduced,—together with the 
Taconic formation of Professor Emmons.
