214 CC. A. Goessmann on the Onondaga Mineral Springs. 
1000 parts of this water left at 200° to 212° F., 08906 parts of 
solid residue; one gallon would consequently leave 3°36525 
grams or 51°9849 grains. 
b. Water taken from a well sunk from the top of Prospect 
Hill, to a depth of seventy-five feet, i. e., the level of Salina street 
at the corner of Lock street. Prospect Hill lies about midway 
between the well which furnished the water for Analysis a, and 
the northwestern termination of the high embankment (80 or 
40 feet) around the eastern and southeastern shores of Ononda- 
ga Lake and its adjoining low lands. Prospect Hill consists 
mainly of gravel and is covered with numerous boulders, and 
underlaid with the red clay of the Onondaga Salt Group. The 
gravel is here and there interspersed with layers of cemented 
gravel (hard pan) and of a red loamy soil. These layers are of 
varying extent and apparently without any order of succession. 
The water subjected to analysis was taken from the first quanti- 
ties drawn from the well soon after its completion (April, 1868). 
Quantitative tests for carbonic acid and iron, being under exist- 
ing circumstances of no value, were omitted.
