368 C..A. Goessmann on the Onondaga Mineral Springs. 
entific public now more apt to give a hearing to our theory, we 
intend to publish a series of articles, giving the properties of 
the chemical elements as functions of their atomic weight, this 
expressed as in the few instances given in §30. We hope to 
prove that the unity of matier is as real as the unity of force— 
‘both being the creative work of one all-pervading being.

III. How does carbonate of lime act upon a solution of chiorid of 
magnesium ?—I boiled for sixteen hours two grams of finely pul- 
eblorid of caleium; while freed magnesia enters into com- 
bination with the main bulk of its chlorid, forming a soluble 
oxychlorid. The duration of treatment and the temperature 
influence, to some extent, the degree of change, which in itself 
peratures, 
IV. How does carbonate of magnesia act upon chlorid of caleium ? 
—A solution of 0-7660 grams of chlorid of calcium in 50 cub. 
cent. of water was boiled for nearly an hour with an excess of 
carbonate of magnesia, equal to 10264 oxyd of magnesium when
