ard by which to study and compare the strata of all the Northern, 

 Eastern, and Western, States, and by which to unravel all the 

 main features of American palaeozoic* geology. The New- York 

 Reports have been text-books for observers elsewhere, and the 

 same local names given in them to the various strata are known 

 and used ovei; almost half the continent. 



This Geological Cabinet is intended, when completed, to 

 exhibit specimens of all these rocks, and especially of their 

 organic relics ; which will be made accessible also to the scien- 

 tific world at large, by being fully figured and described in Pro- 

 fessor Hall's work on the Palaeontologyf of New- York, now in 

 its third volume.
