THE OCEAN WOULD. 
sulphates of magnesia, potassa, lime, and other substances which the 
water of various seas is found to contain. 
In the year 1847, I made an analysis of water taken a few leagues 
from the coast at Havre, which gave the following result, from one 
litre (1 pint ‘760773):* 
Grammes 
Chloride of sodium 25 704 
Chloride of magnesium 2*905 
Sulphate of magnesia 2*462 
Sulphate of lime 1*210 
Sulphate of potassa 0*094 
Carbonate of lime 0*132 
Silicate of soda 0*017 
Bromide of sodium ... 0*103 
Bromide of magnesium 0*030 
Oxide of iron, carbonate and phosphate of mag-1 Only 
nesia, and oxide of manganese . / traces. 
32*657 
The water of the Mediterranean contains more salts than that of 
the ocean. 
The following are, according to M. Usiglio, who was one of a 
commission sent to examine the different kinds of salt water in the 
south of France, the component parts of one hundred gallons of 
Mediterranean water : 
lbs. 
Chloride of sodium 
29-524 
Chloride of potassium 
0-405 
Chloride of magnesium . 
3-210 
Sulphate of magnesia 
2-477 
Chloride of calcium . 
6-080 
Sulphate of lime . 
1-557 
Carbonate of lime 
0114 
Bromide of sodium 
0-350 
Protoxide of iron . 
0-003 
Total . . . 43-735 
We conclude, from the quantity of sea salt contained hi the water 
of the ocean, that, if it were spread over the surface of the globe, it 
would form a layer of more than thirty feet in height.
