306 GEOLOGY OF OHIO. 
water issuing from the ice at that point would be left undisturbed, and 
would be preserved to the present time. The obliqueness of the strati- 
fication, and the sudden changes in the kind and arrangement of mate- 
rial making up the strata, together with an occasional mass of unassorted 
glacier clay included in the stratified portions, not only indicate the 
force and direction of the torrents of water and an interrupted supply of 
Drift, but also the presence and agency of thick glacier ice at the time 
of deposition. 
Wells and Springs.—There are in the county a number of copious, 
strongly sulphurous springs, the best known of which are those at Dela- 
ware, and near Sulphur Spring Station. _ Besides these, others are found 
in various parts of the county, styled chalybeate, and others magnesian. 
The most frequented is that on the grounds of the Ohio Wesleyan 
University, at Delaware, which is strongly sulphurous. Of this, Prof. 
H. Mitchell, in giving his analysis of the water, says, according to 
Howe’s Historical Collections of Ohio, 1848: 7 
‘*Of gaseous products, I find that one wine pint of the water, taken immediately 
from the spring, contains, of sulphuretted hydrogen gas, 12 cubic inches; of carbonic 
acid gas, 3 inches. One hundred grains of the deposit, which resulted from evapor- 
ating several gallons vi water, yielded, on analysis, of muriate of soda, 48 grains; of 
lime, 20 do.; sulph. magnesia, 16 do.; sulph. lime, 8 do.; carbonate of soda, 5 do. ; 
total of the above, 97 grains. The above results show that these waters approach as 
nearly to the well-known waters of Aix-la-Chapelle and Harrowgate, as those do re- 
spectively to each other. They are directly deobstruent, and calculated to remove 
glandular enlargements, as well of the liver as of the other viscera. In cases of slow 
fever, disturbed state of the functions of digestion, or more confirmed dyspepsia, 
morbid secretions from the kidneys or bladder, gravel, or chronic eruptions on the 
skin, I can strongly recommend their use; and, though last, not least, their power of 
subduing general constitutional irritation, and quieting and restoring tone to the sys- 
tem when it has been necessary to have recourse to the frequent and long-continued 
action of calomel or other mercurial preparations, is, | am persuaded, of the greatest . 
efficacy.” 
The sulphur springs at Delaware, located near the Ohio Female Wes- 
leyan University, and on land of G. W. Little, are of the same general 
character. 
The same may be said of the very copious sulphur spring in the left 
bank of the Olentangy, on Mr. Wm. Case’s land, in the southern part of 
the county. This, however, presents°the most copious natural flow of 
highly sulphurous water known in the county. | 
The artesian sulphur spring at the Reform and Industrial School for 
Girls, at Lewis Center P. O., was formerly a place of much resort. This 
well was drilled in 1820. The water rises from the depth of about ninety
