3. Analysis of Arctic Sea Water. 



The numbers are from the tickets pasted on the bottles. 

 No. 2. Four feet below ice (with alkaline reaction). 

 No. 7. Ten fathoms, spring tide (with alkaline reaction). 



Composition of Arctic Sea Water, calculated from the preceding 



Table. 



These waters are characterized by the presence of a larger quantity of Car- 

 bonates of Lime and Magnesia, particularly of the latter, than is usual in sea- 

 v.ak-r; no doubt due to the proximity of rocks containing these earths. The 

 \vaters possessed a strongly alkaline reaction, derived from the influence of these 

 earths in their soluble condition.
