. * Reduced by Humboldt's observations. 



t Height estimated. When a place is said to be at the level of tide water, the height of 

 the instrument is assumed at 50 feet. 



{ Mean temperature as observed, reduced to the level of the sea. 



Note. The observed temperature of Nain, Cincinnati, Philadelphia, Natchez and Ha- 

 Tana, was taken from a table in the Rridgewater Treatises; that of VVashington and New- 

 port from the Meteorological Register of the U. S. A ; that of Quito from Rees' Encyclopae- 

 dia, and that of places in New-York from the Regents Report. 



BEDS OF OYSTER SHELLS ON THE HUDSON RIVER. 



Having occasion to visit Rockland county not long since, I went 

 ashore at Slaughter's Landing, near the great ice depot. The 

 shore at this place is quite steep, and closely skirted by the great 

 range of greenstone columns, resting upon, and interlaminated 

 with beds of the new red sandstone. This place is interesting on ac- 

 count of the effects which the greenstone has had upon the subja- 

 cent rocks, particularly for the remarkably distinct signs of pow- 

 erful igneous action. But the facts which I propose to speak of, 

 are the beds of oyster shells some sixty or seventy feet above the 

 nver. These beds are just below the surface of the soil in which
