ITS PHYSICAL CONSTITUTION, ETC. 



LET us transport ourselves to the sea-shore, 

 to which the valley where we have lingered so 

 long conducts us. What matter of thought and 

 investigation lies before us in this restless and 

 majestic element, whose waves cast themselves 

 at our feet, shedding their salt spray over our 

 persons ! Are the principles of chemistry in 

 movement throughout this mighty deep, as we 

 have seen them on the earth and in the air, 

 producing their slow but ceaseless changes of 

 form and matter? This inquiry it is our pre- 

 sent object to satisfy. It may, however, be 

 premised that the chemistries of the ocean are 

 few and simple, far more so than those of earth 

 or air ; but they are not less interesting nor less 

 important.
