The results of the above experiments shew,, that the water 
of the ocean, from north latitude 61® 52' to north latitude 78® 
85' does not differ essentially in the quantity of saline matter 
which it contains ; the smallest quantity being 3.27 per cent., 
the greatest 3.91 per cent,. The average quantity of saline in- 
gredients in the water within these latitudes is 3.5 per cent. 
If the experiments of Pages be correct,, the saline substance 
contained in'the water of southern latitudes,^ is greater than that in 
the water north of the equator. At south latitude 20° the saline 
ingredients amount to 3.9, and at south latitude 46° to 4.5 per 
cent. ; while the greatest quantity in the water of the north seas, 
according to my experiments, is only 3.91 per cent, in water pro- 
cured at north latitude 78° 25', upwards of 30 degrees farther 
distant from the equator than the southernmost latitude at which 
F^es collected the water on which his experiments were performed-
