C. A. Goessmann on the Chemistry of Brines. 81 
Analysis No. 1 is from the brine of a particular well at Syra- 
' cuse, and represents that brine, as far as figures have been given, 
in its original composition ; analysis No. 1 is obtained from that 
same brine after being brought simply to the point of saturation ; 
analyses Nos. 111, IV, V, are from mixtures of brines from different 
wells; they were collected at different stages of concentration and 
the subsequent separation of the crystallized chlorid of sodium, 
The discrepancies in regard to the varying relative propor- 
tions of the chlorids of calcium and magnesium observable in the 
foregoing statements are due to some slight differences in the 
composition of the original material subjected to evaporation. 
stated on a former occasion that within a certain limit these brines 
differ somewhat in regard to the relative proportions of the deli- 
other hand, varies in quantity in the different layers of crystals
