The analysis shows that this rcsembhmce in tasto is due to a 

 great siniihirity in chemical composition. The watei* for analysis 

 ■was collected at the spring by myself during the first week in 

 August. 



The analysis of the German Seltzer Water was made by Kastner, 

 and reported for one pound of Avater : for comparison it has been 

 recalculated for one gollon. 



In one gallon of 231 cubic inches are contained — 



Saratoga Soltzer. German Seltzer. 



C. P. Chandler. Kastner. 



Chloride of sodium 234-291 grains. 132-673 grains. 



Chloride of potassium .. . 1-335 " 0-469 " 



Chloride of lithium 0-562 " 0-003 " 



Bromide of sodium 0-630 " 0-001 " 



Iodide of sodium 0-031 " 



Fluoride of calcium trace. 0-012 " 



Sulphate of potassa 0-557 " 2-217 " 



Bicarbonate of baryta trace. 



Bicarbonate of strontia .. trace. 0*083 " 



Bicarbonate of lime 89-869 " 19-288 " 



Bicarbonate of magnesia . 40-339 " 22-354 " 



Bicarbonate of soda . .... 29-428 " 77-295 " 



Bicarbonate of iron 1-703 " 0-919 " 



Bicarbonate of manganese, 0-027 " 



Phosphate of lime trace. 2-328 " 



Alumina 0-374 " trace. 



Silica 2-561 " 1-905 " 



Boracic acid trace. 



Total 401-680 grains. 259-574 grains. 



Carl)onic acid o-as 324-08 cubic in. 228*736 cubic in. 



From these analyses it appears that the Saratoga Seltzer con- 

 tains a few substances not found in the German, and although 

 these substances occur in very small quantities, they undoubtedly 

 add to the value of the water. 



In strength, the Saratoga Water is superior to the German, as 

 well as in the quantity of carl)onic acid gas. 



The peculiaHty of the Saratoga Seltzer, in which it differs from 

 all the other Saratoga waters, is, that while it is mild and pleasant, 

 and can be used as a beverage, alone or with wines, as the German 

 Seltzer is used, it contatns a sufficient quantity of mineral matter —
