calcium and magnesium, were detected. Crenic and apocrenie 
acids were in vain sought. A trace of organic matter was found 
dissolved in the water. The only alkali present is soda in the 
state of chlorid of sodium. No trace of potassa was discovered 
after a careful search. Mr. H. C. Lawrence kindly undertook 
the concentration of eleven and a half wine gallons of the arte 
sian water, which were boiled down to half a gallon; a coneél
